What Does a “925” Mark Mean When Stamped on a Silver Ring?

Many wonder.  What does a 925 mark mean when stamped on jewelry?

Like many jewelry markings, the 925 stamp is something which those outside of jeweler circles may find mystifying.

While the answer is simple, the history behind it is much more fascinating.

If you’re curious, then read on.  We will answer the question – what does a 925 mark mean when stamped on jewelry?  Then we’ll give you a breakdown of the history behind the 925 hallmark.

So, what does a 925 mark mean when stamped on jewelry?

The 925 stamp indicates that the piece of jewelry you’re holding has been created with sterling silver.

Sterling silver is an alloy that is made of 92.5% actual silver, with the rest of the metal made up of base metals like copper.

The reason behind this alloy is that it’s much harder than the 99.9% required for “fine” silver, which makes it better for practical objects. Jewelry can also benefit, particularly rings and bracelets which are more often exposed to getting dented or scratched than pendants or earrings.

The vast majority of sterling silver contains copper as the alloying material. That said, there are plenty of other additives that see use but still meet the sterling standard.

Still, in the bulk of cases, the 925 stamp indicates what you’re holding is 92.5% silver and 7.5% copper by weight.  In order for a silver to be classified as sterling silver, it must meet at least a 92.5 purity, AKA 925. So, as you can see: 925 silver is the same thing as sterling silver.

Sterling silver allows for easy working, while still maintaining the majority of white shine that typifies the precious metal.

What Do Other Stamps Mean?

For the most part, it’s relatively easy to figure out the meaning of a mark.

While many of the European nations have their own stamps, numbers are becoming more common to indicate purity in the interest of international trade.

Usually, you can simply add a decimal beforehand in order to figure out what the numbered stamp means. A 999 stamp would, for instance, indicate that the metal was fine silver instead of sterling.

What Does a “925” Mark Mean When Stamped on a Silver Ring - Luxuria Diamonds
CHART 1: What does a 925 mark mean when stamped on jewelry?  This chart shows common marks for Silver, Gold, Platinum and Palladium.  Markings may differ, depending on which country the jewellery originates from.   For example in the USA gold is typically stamped 10K (or 10kt), 14K, 18K or 22K.  Gold plated jewelry is commonly stamped GP, GEP, RGP, HGE, or HGP. Silver may also be stamped STER, STR, SS or Sterling.

International standards on silver vary by a lot and many pieces are sold unmarked.

It’s a good idea to make sure that you know what you’re buying as silver from some areas is notoriously impure. German silver, for instance, is only 80% silver. Egyptian silver, perhaps the most notable example of near-fraud, is only required to be 60% silver.

Sometimes jewelry makers will seek to get around standards by not stamping metals in countries where it’s not required and will only indicate the origin of the metal instead of the actual purity.

Beware of silver jewelry that is not stamped! The absence of a unattested fineness mark means the metals are not identified. Frequently such product takes a cheap base metal and plates it with a thin layer of silver.

Luxuria Diamonds

The quickest way to identify sterling silver is to look for a mark or stamp, called the “fineness mark.” The fineness of a precious metal object (like silver) represents the weight of fine metal therein. Certified sterling silver will be stamped or marked with the word “sterling” or “925.”  

You may often come across alternative hallmarks such as “STG” “SS” or “STER”.  Though rarer these if probably used are also authentic notations of sterling silver.  Furthermore older British jewelry from the mid 19th century to the mid 1970’s may have a forward facing Lion Passat standard mark.  This also represents silver. See the above chart.

As a consumer, it’s your job to make sure that you’re getting what you pay for. The precious metal trade is rife with fraud to this day, but a savvy customer can get along without getting ripped off in the meantime.

925 Silver Testing

If there are no silver stamps on the jewelry then this may indicate the jewelry is plated.  It may be best to have such a piece tested.

Jewelers do such tests by applying acid to a very small piece of material taken from the jewelry.  Silver is a precious metal and its authenticity should be verified.

A Nitric Acid Test is typically used to check if silver is pure or plated. To do so, jewellers file a small part of the item in a discreet area where it cannot be seen. Jeweller then apply a few drops of nitric acid. If the area turns into creamy white, the silver is pure or sterling. If green, it is probably fake or silver-plated.

The History of Stamping Metals

Stamps have existed since ancient times as a way to show the purity of precious metals. In many ways, these were actually among the first forms of consumer protection.

In Europe, the tradition of hallmarking stems from the simple fact that frauds have always been rampant anywhere that money can be made. The assaying process assured consumers that they were getting what they paid for and not a similarly colored metal.

The British had a very intricate method of stamping their metals. These include a stamp from the assay office, with different offices in different towns having their own stamps, a date mark, and the assayer’s mark indicating purity. Added to this was the maker’s own stamp.

The system used in England has changed over time and the assay office town stamp is no longer necessarily an indicator that the town in question was actually where the item was assayed.

While not entirely standard, the early United States didn’t adopt their own standards until the 1860s. Before this, the vast majority of silver was obtained by melting coinage and there were no formal assay offices. Instead, pieces were marked with “COIN” or “PURE COIN” to indicate the origins of the silver.

The US adopted the sterling standard in the 1860s. Unlike the intricate marks used in Europe the majority of items that met the sterling standard were simply marked “STERLING” or “STERLING SILVER”.  Many vintage marks, but far from all, include the name of the manufacturer.  These stamps can offer good insight into the origin of a piece.  In very rare instances, American silver from the period of the 1860’s to the 1970’s was marked only 925.

Hallmarking is a complex subject, especially when it was done before modern times. The assays range from complete destruction of part of a batch of objects to simple touchstone processes. How things are done largely depends on the office and origin.

Which countries have a Hallmark System?

A hallmark is an official mark or series of marks struck on items made of metal. The purpose is to certify the content of precious metal. Precious metals include platinum, gold, silver and in some nations, palladium.

Many countries, including the U.S., do not have an official hallmarking system.  Further, hallmarks of one country can vary dramatically from another.

In many places, especially Europe, it’s required that a maker register their mark at a hallmarking or assaying office so it can be tracked.

In most European countries, including France and Great Britain, an item is not legal for sale without a hallmark. Germany doesn’t have hallmarking, but it’s the exception.

A few countries, like Austria and Norway, have optional hallmarking. Italy doesn’t require hallmarking but it has better registration of the maker, a specific number, so what you see as an Italian mark was placed there by the maker. It’s a little more formal than any other maker’s voluntary marking.


What do other Symbols stamped on jewelry mean?

In addition to raising the question of what does a 925 mark mean when stamped on jewelry – we are often asked other 925 ring stamps?   What do other symbols stamped on jewelry mean?

Other than the 925 jewelry stamp the other key stamp is the makers mark.   The makers mark is the stamp representing the jeweller, manufacturer or brand which made the ring.

The makers mark is a unique stamp placed on jewelry to identify who made it.   The mark sometimes referred to as the sponsors mark also ensures the authenticity of the manufacturer.

Makers marks or stamps are typically made up of the manufacturers initials, often two or three letters.   However they can also be a logo, brand name or some other unique representative symbol.  Identifying this mark is very important and a key step in determining provenance and value.

We also have a page we are building on contemporary makers marks.  We find Hallmark directories and guides are useful for antique jewelry.   However Maker’s marks aren’t nearly as well documented as hallmarks.


Is 925 Mark Silver a Good Choice for Rings?

Absolutely. Sterling silver is one of the best materials around when it comes to ring construction. It has a traditional precious metal feel while remaining hard enough that you won’t have to worry about damaging it in normal use.

Sterling silver is still a standard in jewelry, few pieces are ever made with fine silver since it’s so soft. Those that are made of fine silver are generally fine pieces made as pendants or earrings.

It’s long-lasting, tarnish-resistant, and easily cleaned in the event that it does antique. There’s a reason the sterling standard exists: except for purity it’s superior in almost every way to fine silver.

Looking for a Sterling Silver Engagement Ring?

Now that you know the 925 stamp’s origin and what it means for the metal involved you likely feel a bit more confident in your ability to select silver.

Many people are opting for sterling silver as the base metal of rings these days. It’s hard, long-lasting, and costs less than gold.

      Hello Leonard, It means the necklace is most likely gold Vermeil, in which the base metal is 925 silver over which a gold plating is applied. Please note the gold plating is usually very thin, can be damaged and will wear off with use over time.

    • Ralph Ede

      Hello Tina,

      In reply to your question of what does NVC 7 and 925 mean when stamped in a silver ring we reply as follows

      NVC is the makers mark. This mark belongs to a manufacturer who was commissioned by AVON Products Inc. of New York to make rings and other jewelry items for the brand. In the mid 1970’s AVON had established itself as the world’s largest costume-jewelry producer. While this is no longer the case today AVON continues to subcontract manufacture of jewelry globally. The vendor who manufactures for AVON is usually identified by a two or three character (usually letters) additional mark on the jewelry. The NVC mark on a ring is typically followed by a number. This number is the USA ring size, so NVC 7 means it’s a USA size 7 (average for women) ring. See photos below of NVC 6 and NVC 7 stamped rings.

      The 925 found on the other side of ring band is the millesimal fineness mark for silver. Therefore the metal content of the ring is likely to be 92.5% silver which is alloyed with some other base metal to strengthen it typically copper but could include zinc and nickel.

      925 NVC 7 stamped on jewelry meaning NVC ring
      Photo: NVC 7. NVC refers to a manufacturer commissioned by AVON © to produce jewelry for them. 925 rings stamped with NVC will usually be followed by a number which refers to USA ring size. So NVC 7 means a US size 7 ring.

      Without sighting and testing the ring it is difficult to be sure Rachael. If the ring is gold in colour we’d say it is most likely gold vermeil. If the “gld” was in capitals i.e. “GLD” it could represent a makers mark (usually the initials of the maker / designer) or a brand mark. But as you’ve mentioned gld is in lower case we assume that’s attempting to communicate its gold but when used in combination with 925 i.e. “gld 925” we’d take it to mean a 925 silver ring plated with a layer of gold. Hope that’s useful.

    • Ralph Ede

      Hello Nathan,

      When 925 is stamped on Jewellery it usually means the metal material is silver alloy. Sterling silver is usually 92.5 per cent pure silver and 7.5 percent copper, but other metal(s) are sometimes used in place of copper, for example nickel. We are not familiar with the “MA” inscription. “China” simply means the jewelry is made in China.

      With respect to worth, it really comes down to the material content. Silver is a precious metal and its value – along with gold – has surged in recent times, reaching its highest peak in 6 years. Recent spot prices are over US$20 per oz. Many investors currently see precious metals as a safer store of value in these uncertain times. However, we’ve seen many made in China rings which were stamped 925 but in fact were silver plated over a base metal. These have no market value.

    • Ralph Ede

      Ra, From your description we’d say it’s almost certain the jewelry is plated. Jewelry is often plated with a very thin layer (measured in microns) of 925 silver in order to keep prices low.

      The metal alloy could be anything but usually consists of cheap base metals, for example brass which is an alloy of zinc and copper. Mass-produced fashion jewelry often contains copper or copper alloys.

      Much of the time the contents of the metal alloy aren’t disclosed. Some alloy’s include nickel which if it comes in contact with skin can cause allergic contact dermatitis, with symptoms including rash or bumps on the skin, itching, redness or changes in skin color.

      You don’t provide much information on the ring so it’s difficult to make a determination. In general , silver makers marks are characterized by two or three letters and/or an identifying symbol which we can look up in a Jewelry hallmark publication.

      An “L” following a “925” purity stamp is not a maker’s mark that we are aware of and therefore gives no clue on who the maker is. We suspect the “L” in this instance is actually intended to identify the ring size. L is a UK ring size (the letter size code is also used in other countries such as Australia and New Zealand ) and is the equivalent of USA ring size 5 ¾ . Does that make sense to you?

    • Ralph Ede

      Hello Janie, regarding your question of what does BY 925 mean when stamped on a ring, we reply as follows.

      The BY in the BY 925 ring stamp is the makers mark. This mark belongs to Bijoux Continental of Montreal, Quebec . Bijoux Continental was a maker of gold and silver chains, rings, earrings, bangles and fashion jewellery until their manufacturing closure in 1998.

      Another possibility is the BY mark has also used since the 1970’s by Benson Yazzie, a Native Indian (Navajo) maker of custom / handmade jewelry usually using Sterling Silver and Turquoise. This however seems a little less likely because Benson Yazzie typically uses STERLING rather than 925 as a millesimal fineness mark, i.e. the ring would more likely have a BY STERLING stamp rather than BY 925. Another point of differentiation is that Benson Yazzie’s work is typically hand stamped or engraved thus the jewellery marking looks somewhat less tidy than the BY 925 mark used by Bijoux Continental jewelry.

  • Charles Wheeler

    Ive ran across a tennis chain and marking on the clasp is DA then 925 is upside down. Could these be diamonds. Its large 32 grams and guessing 10 plus carats if so. Thanx in advance

    • Ralph Ede

      Hello Charles,

      We’ve seen DA 925 stamped on a wide variety of jewellery.

      DA or more commonly D-A is used by Norwegian design house David Andersen. While the house has employed a number of different modernist designers over more recent decades, its signature styles don’t really encompass and embrace tennis chains so we doubt your piece originates from there.

      DA 925 can also be found stamped on mass produced made in China silver and silver plated jewelry. For tennis chains diamond simulants, largely cubic zirconia, is commonly used in place of natural diamond. We doubt your chain has natural diamonds as gems are more usually set in more precious and stronger metals such as gold. Only testing could provide a definitive answer though. Finally, please be aware that even if the stones turn out to be diamonds they will most likely be only of non certified promotional grade. Hope that helps and all the best.

    • Ralph Ede

      As a rule of thumb, virtually all silver rings or other silver jewelry marked or stamped 925 or sterling 925 are modern.

      The 925 standard mark became the international convention in millesimal expression (i.e. 925/1000) in 1976 when it was jointly agreed to by Europe, England and the United States.

      That said, the 925 standard mark was also very rarely used in vintage American silver. However, the vast majority of US jewelry circa 1860’s to 1970’s is marked STERLING or STERLING SILVER and often includes the name of the manufacturer.

  • Joel Holland

    I like buying vintage Native American pieces. But what does the “EDE” stand for on the .925?
    Also, how old is it usually if it’s marked 92.5?

    Thank you…

    • Ralph Ede

      As you are a collector of native American jewelry we’d urge you to consider the purchase of books like Hallmarks of the Southwest by Barton Wright. This particular book (there are other options to) appears to be a very useful tool for identification of individual hallmarks. It was originally published in 1989 so it doesn’t cover more recent silversmiths but for jewelry to be considered “vintage” it needs to be about 30 years old anyway.

      We are not specialists in this area and our current hallmark guides don’t cover this niche. A quick glance online suggests the EDE .925 hallmark or EDE 92.5 hallmark is modern and possibly of Navajo tribal affiliation but the jewelry designs we’ve seen have more of a mass produced rather than handcrafted feel and this observation is supported by their low asking prices. Furthermore, the hallmarks we’ve seen in photos of are modern 925 stamps pressed into silver raising further doubts that some of the vintage native American jewelry advertised – is vintage.

      Bottom line? Sales of fake native American jewelry are on the rise. Hopi, Navajo and Zuni style jewelry offered for sale in various marketplaces is actually being manufactured offshore in Asia. It’s not uncommon for plastic or synthetic acrylic resin or dyed Howlite to be used in place of natural turquoise, so please take care.

  • Lee

    Are these type of rings worth anything? I’m not selling mine as it is my engagement ring AND a family heirloom but I’m just curious.

    • Ralph Ede

      If your ring is silver and stamped 925 then absolutely the ring has value because silver is a precious metal.

      Silver is valued in USD per ounce. In fact the price of silver has increased by over 40% year to date in 2020. Some investors who want protection against inflation buy silver and gold as inflation hedges and this precious metal demand drives up value.

      If the 925 mark ring is also set with precious and/or semi-precious gemstones these will also add to the rings value. A qualified jewelry valuer is the best place to have the ring assessed if you have an interest.

      Of course being a family heirloom, the sentimental value trumps everything else.

    • Ralph Ede

      The SO mark which appears in our hallmark guides, though is typically framed, is the hallmark of Austrian jeweler, Salomon Ordner. However, you mention the use of fake diamond which is a recent advent so we can discount that maker’s mark. Further, makers marks are typically in capital letters and yours appears in lower case which means its unlikely to signify a specific jeweller and therefore very difficult to identify.

      In summary, what we can say is for “so 925” the “so” is likely to be a manufacturers stamp of a costume jewelry manufacturer. It’s also possible, that the “so” refers to a location with SO being a provincial code of Sondrio, Italy. If that holds true though we would have expected to see for ITALY marked or stamped on the silver chain too. 925 of course is the stamp for sterling silver, which likely means that your chain is 92.5% silver.

    • Ralph Ede

      Checking our hallmark guides the AM hallmark has been used by numerous jewellers over the past 100 years. Focussing on silversmiths we note AM was the makers mark used by various jewellers from central Europe (notably Austria) and the UK, some dating as far back as the late 1800’s. More recently AM is also the makers mark for Danish jeweller Anton Michelsen and costume jewelry manufacturers from Mexico and China have also used “925 AM” mark.

      The use of the 925 stamp is an indicator that the ring is not particularly old because the 925 stamp is a relatively recent mark. In America, most silver jewelry made between 1860 to 1970 and especially items made before 1940–are marked “sterling” or “sterling silver. The general rule is that virtually all pieces marked 925 or sterling 925 are relatively modern so we are confused by your comment that the ring has been handed down generations. Perhaps you could send us a photo?

  • Lizzie

    I have a silver ring stamped 925 with a round Symbol next to it but I can’t make out what the symbol is ? It also has 5 fake/real ? Diamonds on. Looks amazing but is it fake ?
    Thank you

    • Ralph Ede

      Hello Lizzie. As the symbol next to the 925 is unclear we are not able to look up our hallmark guides to identify the maker. As to whether the 925 stamped ring is mounted with natural or fake diamonds – only testing by a qualified jeweller could provide a definitive answer. If we were to take a guess we’d say the diamonds are actually simulants or at best very low grade diamond because its rare to set natural diamond into sterling silver. Real diamonds of any substantial value are usually mounted in either Platinum or gold because these are more durable and precious metals.

    • Ralph Ede

      Hello Julia, Re your question on GP 925 13, as noted in our blog “What does a 925 mark mean when stamped on jewelry”; GP usually means gold plated, 925 means 92.5% silver so GP 925 would typically mean the jewellery is gold plated over a sterling silver base.

      As for the 13 it may indicate a size or length – for example if this piece of jewelry is a ring the GP 925 13 may indicate a USA size 13 (mans sized) ring. Another more remote possibility is that the 13 refers to the karat of the gold plating. 13k gold is 54.17% Gold and 45.83% alloy.

    • Ralph Ede

      Hello Pam,

      In a possible answer to your question on what does 925IRRTH means when stamped on jewelry, we’d likely break it down to 925 IRR TH with 925 being the fineness mark for sterling silver – in this case being the precious base metal, IRR likely being the jewelers makers mark and TH being the country of manufacture. TH is the country code for Thailand. The 925 stamped earrings will be relatively recent as both the 925 stamp and the TH stamp are considered modern.

  • Phil Dick

    Is there a way of determining genuine Blue John?
    Any simple way of testing it?
    I have a ring which appears not to be old and the ‘gem’ has been polished and wonder if it’s Blue John?

    • Ralph Ede

      The very first observation we’d make is that its relatively rare and certainly not recommended to have this unique Fluorite gem mounted in a ring. This is because Blue John is fragile and brittle and being rated at only 4 on the Mohs hardness scale – is unsuitable for most jewelry use, especially rings. Even in earrings and pendants the gem needs a protective setting.

      So the fact your gem is ring mounted is a strong indication it might not be Blue John. Further, if it was a real Blue John we’d expect to visually see surface scratches if the piece has been worn.

      As for testing you need a refractometer to at least first establish the gem is a Fluorite. Fluorite’s very low RI (1.432-1.434) and dispersion (typically around 0.007) can quite easily distinguish it from many other gems.

      Furthermore some (but not all) fluorites display fluorescence under ultraviolet light (UV), but we’d caution that the presence of fluorescence is not conclusive for gem identification.

      Conclusive testing requires a qualified jeweller or gemmologist.

    • Ralph Ede

      Hello Tedi. We’ve seen the STE◇BEE mark on some jewellery, sometimes with the STE BEE being encircled by an oval. Given the description you’ve provided we’d guess the ring, possibly an anniversary band, is gold plated over 925 sterling silver with the 7 diamond simulants likely being cubic zirconia (cz).

      STE is sometimes used, incorrectly we feel, as a short form for Sterling. If it’s necessary to convey sterling it is more usual for the stamp to be STER, STR or SS. In ages past STERLING was engraved.

      BEE is likely the makers mark / brand. Looking up our Hallmark guides we see the mark is used by a few different makers / manufacturers and its difficult to assess to which your ring belongs without sighting the ring. For example Bee is the maker mark for an Australian jewellery manufacturer, Bee Jewellery PTY Ltd. We discount them because the 925 Bee stamp used generally is with lower case e’s in the Bee mark. More likely your ring is from a mainland Chinese manufacturer of costume jewellery which uses the capitalised BEE jewelry stamp. If this is the case please be careful as various descriptors like “vintage” and material fineness i.e. 925 / 1000 are not always true.

    • Ralph Ede

      Hello Angela, while the 925 stamp on jewelry is self-explanatory being a mark of material fineness, the 8J in front of the 8J925 is an interesting mark. Instinctively one would think the 8 refers to USA size 8 ring size but you’ve discounted that.

      Looking up our hallmark guides we find no reference to the 8J stamp on jewelry. This typically means the ring is modern, not from a reputable or well established / known maker or brand and usually (but not always) low cost, mass produced costume jewelry.

      However, are you perhaps misreading the 8J 925 mark? Instead of an 8J925 ring stamp could it be a BJ925 or BJ 925 ring stamp? BJ is a common maker’s mark / designers mark from China, usually of reasonable quality though sometimes misrepresented as being of Native American Indian origin.

    • Ralph Ede

      Hello Heather, rings stamped 925A or marked “925 A” are very common. Unfortunately the 925 A marking in the band is not enough for us to identify ring beyond hinting the ring is set in 925 sterling silver (92.5% actual silver, with the rest of the metal made up of base metals like copper) and that the ring stones are more likely to be zircon, cubic zirconia (cz) or some other diamond simulant, rather than natural diamond.

      Further, as there are no other markings other than 925A the absence of a makers mark or brand mark together with the abundance of 925 A mark rings suggest the silver ring is mass produced. Over 90% of 925A jewelry is manufactured in China or Thailand. Sometimes this is affirmed by an additional location of workmanship stamp such as 925A CHINA or 925A CN or 925A THAILAND or 925A Thai or 925A TH.

    • Ralph Ede

      Hello Jason, regarding your ring marked AE 10 925, the signed AE 10 925 marks or stamps can probably be broken down as follows.

      AE is the makers mark, i.e. the jeweller, manufacturer or brand responsible for the rings design or distribution. We’ve seen the AE mark in a circle as well. The AE 925 mark is used by several designers – a quite common one being American Eagle from New Mexico in the South Western United States. American Eagle Outfitters jewelry is usually signed ae or aeo. American Eagle Jewelry may also be stamped with AE in capitals or have the brand stamped in full i.e. “american eagle”. AE / AEO brand jewelry is mostly manufactured in China and India and has little commercial value.

      Another user of the AE mark is Art’s Elegance Inc. of California. This is less probable because they mostly work in 14k gold and gold plating over 925 silver and are better known for pendants and bracelets. Arts Elegance jewelry can be made from silver of gold or a mixture of both and sometimes includes natural semi-precious gemstones. Their jewelry often contains a copyright mark ©. Further sometimes the AE is contained inside an oval. Unlike American Eagle which is largely cheap costume jewelry Arts Elegance is often demi-fine jewelry. See photos of ae 925 mark and AE 925 mark below.

      Finally, the 10 in the AE 10 925 mark is likely reference to the ring size i.e. USA 10. The 925 mark when stamped on a silver ring indicates the fineness of the material, in this case 92.5% precious silver.

    Hello…. I have a silver ring with, what I would describe as, an art deco design. Large rectangular black stone, surrounded by chipped black stones. The stamp on the inside has what appears to be a capital “A” followed by 925. Im new to vintage identification but I believe I understand the “925” silver stamp. Would like your input on what the “A” means and also how to go about dating this piece. Thank you

    • Ralph Ede

      Hello Jill, Thanks for your question re a ring with a capitalised A925 marking / A925 stamp. The large rectangular black stone may be Black onyx, Black Spinel, Black Tourmaline or Zircon all of which are quite common. If the A is stylised – for example the crossbar is missing from the A i.e. something like Λ , it’s possible the ring maker is Anchalee Products of Bangkok, Thailand.

      Anchalee specialised in mounting semi-precious gemstones into 925 silver and used a stylised A – Λ925 stamp to assert their work. Impossible to date the piece from the information given but possibly late 1980’s to 1990’s if our assumption on the maker is correct.

      Hello Dustin, In reply to your question on what 925 LA TH and 925 LA CN means when stamped on jewelry we reply as follows.

      Breaking it down, 925 is millesimal fineness mark for silver. Therefore the metal content of both necklaces is likely 92.5% silver which is alloyed with some other base metal to strengthen it, typically copper but could include zinc and nickel.

      The LA in 925 LA is the makers mark. The maker mark identifies the manufacturer, jeweler or brand responsible for the jewelry design. LA in this instance probably refers to L.A. Gem and Jewelery Design Inc of Los Angeles, USA. Nowadays you see this 925 LA mark product marketed under various pseudo brands some examples being ShineTM and “Love is ForeverTM”. The A in the LA 925 stamp is often stylized as can be seen in the photos below of typical jewelry signed LΛ 925.

      Finally the TH & CN stamps likely refer to the country of manufacture – i.e. where the jewelry is physically made. It is not uncommon for a piece of 925 jewelry to be designed or branded in one country, but manufactured in another so as to reduce costs. On this basis it is probable the 925 LA TH jewelry is manufactured in Thailand and the 925 LA CN jewelry is manufactured in China (PRC).

      Hello Jerry,
      Regarding your question on what does SK mean when stamped inside a sterling silver diamond ring we respond as follows.

      SK refers to the mark of the maker or the jewelry manufacturer, which is likely to be Scott Kay Inc. of New Jersey USA. Scott Kay specialised in bridal, sterling silver and fashion jewelry some of which is marketed via QVC / Home shopping network and under different brands / marks including 925 SK, SK 925, SK COBALT, SCOTT KAY, ARTISTE and many others. Under new ownership the company is moving toward the luxury market. The SK signed silver ring (SK 925) is more likely to have Diamonique ™ cubic zirconia or some other form of diamond simulant rather than real mined diamond.

      Hello Janie, regarding your question of what does BY 925 mean when stamped on a ring, we reply as follows.

      The BY in the BY 925 ring stamp is the makers mark. This mark belongs to Bijoux Continental of Montreal, Quebec . Bijoux Continental was a maker of gold and silver chains, rings, earrings, bangles and fashion jewellery until their manufacturing closure in 1998.

      Another possibility is the BY mark has also used since the 1970’s by Benson Yazzie, a Native Indian (Navajo) maker of custom / handmade jewelry usually using Sterling Silver and Turquoise. This however seems a little less likely because Benson Yazzie typically uses STERLING rather than 925 as a millesimal fineness mark, i.e. the ring would more likely have a BY STERLING stamp rather than BY 925. Another point of differentiation is that Benson Yazzie’s work is typically hand stamped or engraved thus the jewellery marking looks somewhat less tidy than the BY 925 mark used by Bijoux Continental jewelry.

  • Marcy Telford

    I have a 925 sterling silver and CZ ring which is marked “925 BEE” inside the ring band. The 925 BEE stamp on the jewelry is all in capitals. Could you tell me what the 925 BEE jewelry marking means and where it might be from?

    • Ralph Ede

      Hello Marcy. The 925 BEE mark may be broken down as follows.

      925 is a standard mark for silver. It simply means that the silver content in your ring is 92.5% with the remaining 7.5% being made of other alloyed elements.

      BEE is the makers mark. The mark with the 925 BEE all being in typeset capitals belongs to a costume and silver jewellery manufacturer based in Ningbo, a sub-provincial city in northeast Zhejiang province, People’s Republic of China.

  • Marcie S

    Hi, I have a 925 silver necklace that has a monogram circle with the letters IDB & 925 INDO . Can you please reply with who the maker might be (I know that’s kind of a random question due to there being an enormous amount of possibilities so if you have knowledge of who it might be, that’ d be awesome to know). And I am thinking the “iNDO” could possibly stand for Indonesia.¿ Please correct me if I am incorrect in my assumption. Thank you for your help! Marcie S

    • Ralph Ede

      Hello Marcie,

      We’ve checked our makers mark guides and unfortunately drawn a blank with respect to a jewellers markers mark with of a monogram circle with letters IDB inside.

      Is it possible the marking is actually IBB? Sometimes with age and wear a B can look more like a D.

      IBB is a very common makers mark, often contained within an oval or other shapes, like a rounded three leaf clover / shamrock, the mark belongs to International Bullion and Metal Brokers (USA) Inc., a corporation based in Florida. IBB is a distributor of jewelry including 925 silver necklaces, rings, earrings, bracelets, bangles, chains, anklets, and pendants. Manufacturing is done in multiple offshore locations.

      As far as the 925 INDO marks are concerned, 925 is the millesimal fineness mark for silver, so the maker is claiming the necklace is made of precious silver. The INDO appearing after the 925 likely refers to the country of manufacture, 925 INDO likely indicates the silver necklace is manufactured in Indonesia, though this is far from certain as larger Indonesian jewelry items usually use the country name in full i.e. INDONESIA.

      Comparatively, IBB CN identifies manufacturing in mainland China and IBB TH for manufacturing in Thailand are both more common though we regularly see 925 silver chains with IBB ITALY mark on the clasp or finding. Typically IBB 925 INDO stamped jewelry products have a handcrafted rather than mass produced look and feel to them.

  • Tracey larkin

    Hello I have my mother’s amethyst cocktail Ring she got it in the 1980s in CA and used to wear it quite a bit it was her favorite. It’s gold an very large. Looking inside it’s stamped 925 then a makers mark I guess and china. I was surprised that it was plated because it still looks like gold. Is there a way to find our who made it . The mark is a square with either a 0 or circle in it.

    • Ralph Ede

      Hello Tracy. Your description is an Amethyst gemstone ring, set in 925 sterling silver which is plated in gold and marked as being manufactured in China and signed / stamped with a square with a circle or 0 inside of it and obtained in the 1980’s.

      While our research is inconclusive we feel there is a good chance the square mark with the 0 inside or a square mark with a circle or dot inside identifies this ring as being made by a Chinese manufacturer and supplier on behalf of AVON Products Inc. of New York.

      AVON as you may be aware has its roots as a perfume company going all the way back to 1886. David H. McConnell founded the California Perfume Company in New York City and with the help of a clever businesswoman named Persis Foster Eames Albee; he developed a multi-level marketing business type that empowered women to work for themselves, selling fragrances and toiletries to other women across the United States. AVON did not produce costume jewelry until 1963 but by 1975 it was already the world’s largest costume-jewelry producer.

      Whilst AVON products were largely costume jewelry i.e. of little material value being manufactured in cheap base metals and decorated with resins, plastics and faux gemstones or simulants this was not exclusively the case. AVON used many manufacturers globally for supply and some set rings in precious 925 sterling silver and used natural gemstones. If yours is such an example then it’s considered demi-fine jewellery (vermeil plating + natural gemstones) rare and highly collectable. Of course there is also a chance your ring may contain a faux amethyst i.e. purple infused faceted glass, CZ or rhinestone. Only gem testing would prove conclusive.

      Most AVON jewelry is stamped ©AVOп or with AVOп inside an oval. This identifies the brand. It does not identify who designed or manufactured the piece of jewelry for AVON. The vendor who manufactures for AVON is usually identified by a two or three character (usually letters) additional mark on the jewelry. However, we’ve also seen AVON manufacturer markings matching and similar to your description, some have the appearance of being signed or marked with a 0 inside a box or a solid dot inside a box [the outer box may be rounded] and typically stamped on the inside band of the ring. We attach below examples of this marking which sometimes is not complete or clear due to age and wear, especially if the jewelry is plated.

      Hello Vanessa, regarding your ring marked 925 1BB, we’d be reasonably confident in saying the stamp is actually 925 IBB. Anyhow, what does it mean when a ring is marked 925 IBB? The 925 stamp indicates that the piece of jewelry you’re holding has been created with sterling silver. The IBB stamp is the makers mark and likely indicates your ring is made for the International Bullion and Metal Brokers (USA) Inc., a corporation based in Florida. IBB is a distributor of jewelry including 925 silver necklaces, rings, earrings, bracelets, bangles, chains, anklets, and pendants. Manufacturing is done in multiple offshore locations.

      To the second part of your question you want to know with the 925 IBB signed ring is set with a real diamond? In answer we’d say it’s unlikely. While there are some makers that set low grade diamonds into 925 silver settings; most natural diamond is set in more precious and stronger metals such as gold and platinum. Only testing by a qualified gemmologist or jeweller could provide a definitive answer though.

      Finally, some 925 IBB mark jewelry contains additional marks or stamps including CN or TH [see below photo]. These indicate the country of manufacture – i.e. where the jewelry is physically made. IBB CN 925 for example means jewelry by IBB was manufactured in China and set in 925 silver.

      Hello Grisha. We note you have forwarded us a photo and the three stamps on the ring are 9K 925 and PT. We also note the ring has a makers mark clearly inscribed; Dyadema.

      So what does 9K 925 PT mean when marked on a ring? Rings marked 9K 925 PT should consist of a combination of three separate metals.

      First, 9K gold or 9-karat gold which contains 9 parts of pure gold and 15 parts additional metals. Common alloyed metals include silver, copper, platinum, palladium and zinc. In Europe 9k gold is more usually referred to as 375 reflecting its gold purity which is 37.5%. Gold has to be mixed with harder metals to give it strength and shape.

      Second, 925 which usually is the millesimal fineness mark for silver.

      Third, PT which is the material mark for platinum. While it varies by country jewelry stamped PT must contain a high level typically 950 parts per thousand (ppt) of platinum to legitimately have the PT mark without a fineness qualifier. Of the three metals in the ring Platinum is by far the most valuable.

      We can’t guarantee the markings or our interpretation are accurate and it’s possible the ring is essentially 925 and merely plated in gold. We say this because it’s rare to have platinum and silver on one ring. Further, we doubt the ring is 92.5% Platinum which is another possible meaning for the 925 PT mark. Only actual metallic content testing would be conclusive.

      Looking at your ring the 9K is likely the rose gold coloured outer bands. Given the quantity, the stones are likely to be crystals or cubic zirconia. The design is reminiscent of a spinner ring common to Israel.

      Finally, the makers mark seen is Dyadema. Dyadema S.R.L was founded in 2014. We are not familiar with Dyadema but understand it is located in Loria, a comune in the Province of Treviso in the Italian region Veneto, located about 50 kilometres northwest of Venice. Jewellery products from Dyadema are mostly sterling silver and said to be made in Italy and distributed in Italy, the USA, Canada, England and Australia. We understand that Dyadema have manufactured products in other locations too such as Portugal and Israel.

  • Colin McKenzie

    Hi. I have a metal chain bracelet with a similar clasp to the photo under 26 April above. It’s stamped 925 in 3 places (including the same place on the clasp as in the photo), but there are no other marks. Can I count on it being real silver? If not, what would be the best way to test it?
    Thanks very much.

    • Ralph Ede

      Hello Colin. Whilst most jewelry stamped 925 is indeed 92.5% silver the 925 millesimal fineness mark is not a guarantee. Unfortunately the 925 mark can easily be stamped onto any metal and the frequency of fake 925 silver has increased significantly in recent years.

      Silver is a precious metal and the value of silver which is priced in USD and measured per troy ounce has significantly inflated over the past 1 year. Silver is measured in troy ounces. Each troy ounce contains about 31.1034768 grams of silver, which is slightly higher than a standard ounce which has only 28 grams. Spot prices for silver have increased by over 50% in the past 12 months.

      The fact you are unable to locate a makers mark or any other symbol on the jewelry is a concern. Reputable manufacturers of 925 sterling silver items usually mark them with their trademark or brand mark.

      Honestly, the best way to conclusively test silver content is to take the chain bracelet to a jeweller. They will use a small jeweler’s file to make a discreet mark to reveal if the silver is just plated. The underlying metal or the filed sample pieces can then be tested with a nitric acid. As the acid sinks into the piece a resulting color will indicate the metallic content. Blue for example indicates the metal is nickel which is a common base metal for silver plated jewelry. It is possible to buy test kits online too if you wanted to try silver testing yourself. Some of other DIY silver tests you read online are not accurate.

    Hi! I have a ring stamped JL S925 and am wondering if you can give me any information about it! It is some sort of faux diamond sterling silver ring.

    • Ralph Ede

      What does JL S925 mean when stamped on a ring? We break it down as follows.

      JL is the makers mark. We suspect the JL mark on your ring identifies the ring as being designed and manufactured by Jewellista. Jewellista Co., Ltd is located in Sam Phran, the southernmost district of Nakhon Pathom Province in Thailand, about 40 minutes drive from Bangkok.

      Jewellista has been a manufacturer, distributor, ODM (Original Design Manufacturing) and OEM (Original Equipment Manufacturer) of jewelry since 1987. Its customers include Walmart Inc, USA which is perhaps where your ring was originally purchased. Via ODM they also supply jewelry to Disney and Argos Limited who is a catalogue retailer operating in the United Kingdom and Ireland.

      Jewelry signed JL 925 may use plain or stylised JL characters for the makers mark. See photo below of the stylised JL logo.

      Finally, the S925 mark means the jewelry maker is attesting that the jewelry is made from precious Silver of 92.5% purity.

      Hello Krissy, With respect to your question on what does N 925 CN mean when stamped on a ring we reply as follows.

      N will likely be reference to the brand, manufacturer or maker of the ring. Unfortunately, as you might imagine, N is a very common jewelry mark. There are lots of different manufacturers signing jewelry with an N or N925, so it is difficult to be certain which one made your ring. If the N is stylised in a font similar to the below photo then we suspect the ring may have been made for NES Jewelry Inc, which is based in New York.

      NES Jewelry, Inc. designs, manufactures and wholesales jewelry. The Company offers bracelets, earrings, necklaces, pendants and rings mostly made in 925 sterling silver, stainless steel, brass and alloy metals. Manufacturing is done offshore with NES having offices in Qingdao, Yiwu and Zhuhai, China. Final products are sold via retail partners consisting of large format retail stores such as Walmart, department and specialty stores, specialty chain, TV shopping networks, internet retailers and boutiques internationally.

      As to the balance of the N 925 CN mark, the 925 stamp is a declaration by the maker that the rings metal content is 92.5% silver and the CN stamp indicates that the country of manufacture for the ring is China.

    • Ralph Ede

      Hello Mr. Lambert, a ring stamped 975 and signed franz is an interesting find. To start with 975 silver is rare. As I’m sure you are aware jewelry stamped 975 is claiming the metallic content to be 97.5% pure silver and 2.5% alloy to make it stronger. Fine silver (.999) is pure in form and too soft to be used in most jewellery and certainly not practical for hardwearing jewelry like rings.

      Sometimes, 975 is misread with the actual silver content being 925. It’s not uncommon for the 925 jewelry stamp to wear with time and if the base of the 2 disappears it can look more like a 7.

      Franz is likely the makers mark. Without sighting the jewellery and confirming the makers mark from our database we can’t be certain of the manufacturer / brand. If the Franz mark appears in standard typeset characters and in capitals i.e. FRANZ it may identify it as belonging to a brand based in Berlin, Germany which produced jewelry in precious stones and precious metals decades back but no longer does so.

  • Dee Leadingham

    I have scoured the internet- maybe you can help! I have a 925 ring with a stamp DI on the inside of the ban. Any information would be greatly appreciated!!
    Thank You.

    • Ralph Ede

      Hello Dee, So you have a 925 ring with a DI stamp on the inside band. The DI stamp is almost certainly the makers mark i.e. a reference to the jeweler, manufacturer or brand responsible for design and/or the production and/or the distribution of the ring.

      Looking up our jeweler database we find several using the DI mark on jewelry. There is Diamonds International based in Brisbane Australia which uses the DI mark contained in an indented oval. See the below photo. We don’t think your ring is their work because they mostly work with natural diamonds set in 18k gold.

      A more likely source for your ring is (confusingly) also called Diamonds International but this one is Diamonds International LLC, a New York limited liability company with its principle place of business located in Bronx County, New York. Diamonds International LLC does business in New York, Alaska and Florida within the United States of America and over one hundred locations (port cities) throughout the Caribbean, selling primarily to cruise ship passengers. Much of their range is set in 925 silver. They use various jewelry markings include a typeset DI stamp and a DI stamp including a diamond shape. So jewelry signed DI 925 or DI .925 may have been manufactured for them.

      I hope that helps. We can’t be more definitive without sighting the ring.

    I have gold earrings with THAILAND in one spot and 925 stamped in another spot? Could they be worth anything?

    There are three diamonds: small at the post, center bar diamond and larger diamond at the bottom.

    • Ralph Ede

      Hello Carrie, regarding your gold earrings stamped 925 & Thailand, they will absolutely be worth something. It is likely the metallic content of your earrings is 925. This 925 base will likely have been plated with gold, hence the earrings color. The 925 stamp attests to the purity of the silver, i.e. 92.5%. Silver is a precious metal and has an intrinsic value.

      The three stones are more likely to be diamond simulants rather than natural diamond or if they are natural diamond they will likely be of “promotional quality”, i.e. I-1, I-2, or I-3 clarity diamonds and heavily included (internal imperfections).

      The THAILAND stamp indicates the country of jewelry manufacture. Thai silver is typically high quality. Thailand is a major global producer of silver jewelry and is also a supply source for many precious and semi-precious gemstones too.

  • Alysia

    Hello my bracelet is stamped LA CN and nothing else. What does this mean. I don’t know where the bracelet is from. Thank you for any help!

    • Ralph Ede

      Hello Alysia, In reply to your question on what LA CN means when stamped on a bracelet we reply as follows.

      Breaking it down, LA is the maker’s mark. The maker mark identifies the manufacturer, jeweler or brand responsible for the jewelry’s design and/or distribution. We suspect the LA mark in this instance identifies the bracelet designer or brand owner as being L.A. Gem and Jewelery Design Inc of Los Angeles, USA. Their older jewelry is signed 925 LA and newer jewelry uses various pseudo brand marks such as LA ROCKS which has brand showrooms in Los Angeles and New York. Most of L.A. Gems products appear to be set in 925 sterling silver and accordingly the jewelry is stamped 925.

      Finally, the CN stamp likely refers to the country of manufacture – i.e. where the jewelry is physically made. It is not uncommon for 925 jewelry to be designed or branded in one country, but manufactured in another where the labour and/or material costs are cheaper. Jewelry signed LA CN will likely be manufactured in China (PRC). See photos below of the jewelry marked LA CN.

    Hi there I have a gold colored ring with the exact word “bee 375” stamped on it. It also looks like a dark blue or green sapphire stone (I’m guessing) almost like a black.

    • Ralph Ede

      Hello Sophie. Regarding your gold coloured ring which is stamped bee 375 we have a reasonable level of certainty that the ring is designed and manufactured by or for Bee Jewellery Pty Ltd of Mascot, New South Wales, Australia. The bee maker’s mark is used by them on a wide range of 925 silver and gold rings. Many Bee Jewellery rings are set in 9 karat gold which is represented by the 375 mark on your ring. 375 is a purity mark signifying the gold is 37.5 per cent pure. The remaining proportion of your product will therefore be an alloy of other typically non-precious metals such as copper or zinc.

      The dark blue, almost black central stone may be a natural black sapphire gemstone. Black sapphires come mainly from Australia and are mined in large quantities. This variety of sapphire is cheap and generally considered low grade. So in sum ring signed “bee 375” is likely the work of Bee Jewellery Australia. An example of the bee 375 marking can be seen in the below photo. Does that look the same is stamped on your ring?

      Hello ILyana. Regarding your ring stamped EA 925 we break it down as follows.

      Finally, as I’m sure you are aware jewelry stamped 925 is attesting that the purity of metal used is 92.5% silver. We hope the reply helps you.

    Hi! I have a silver ring with an A stamped on it. The A has a little hat, kind of like an upside down bracket [ with the two short ends facing down. Then it says 925. Then it says D10 in a rectangle. Any chance you know the maker of this ring?

    • Ralph Ede

      Hello Miranda,

      What an interesting 925 ring you have. The ring stamped 925, D10 and A with a symbol affixed on top of the A, a bit like a diacritical mark.

      We break down the meaning of each mark as follows.

      The 925 stamp is a millesimal fineness mark for silver. The fineness is stated in parts per thousand (Arabic numerals) so the 925 mark attests that your ring is 92.5% silver.

      The D10 stamp inside a rectangle is a year mark or date code stamp. The year mark is a voluntary marking that indicates the year of manufacture by means of one letter followed by a numeral or numerals. From the D10 year mark we can tell you two things. First, this 925 ring comes from the Kingdom of Sweden and second the 925 ring was manufactured in 1978.

      The letter A with a diacritical like mark above it is a town mark. A town mark is a voluntary mark that indicates the residence of the manufacturer or the importer. In Sweden, town marks were standardised in 1912 and the town mark consists of one letter that’s usually the first letter of the town’s name, though there are some exceptions. The letter typeface and frame also differentiate one town from another. The A (as described) identifies the ring was made in the city of Västerås. Västerås is a city in central Sweden on the shore of Lake Mälaren in the province of Västmanland, about 100 kilometres west of Stockholm. Västerås is one of the oldest cities in Sweden and Northern Europe.

      Unfortunately your ring appears to be missing a makers mark or a producers trademark so we can’t identify the jeweller or manufacturer of the ring. The makers hallmark is typically either two or three letters, often initials of the makers name or an abbreviation of the name of the maker or company. The absence of a Swedish jewellers makers mark is rare but more common with modern period Swedish 925 jewelry. The absence of a makers mark combined with the absence of Swedish Control Mark to show that the quality of the metal has been analysed by the proper authorities, may hint this particular ring was not made for commercial purposes or to be sold.

      See photo below (lower photo) of a complete set of Swedish hallmarks. This includes (from left to right) a town mark, the Swedish Control Mark, being a small national coat of arms (three crowns) in a trefoil-shaped shield, an S in a hexagonal shield to indicate certification for silver, a date mark [D10 = 1978], a makers mark [SOK = Stina Sökjer Petersen] and a 925 stamp.

    Hi Ralph I read all your replies and hope you can help me out. I got a ring from my grandfather about ten years ago before he passed and it may have been my grandmothers wedding band but I’m not sure based on the stamps inside. She claims it was but I’m thinking the dates don’t line up. They were together throughout the 1960s.

    One side of the ring says CHINA OG (if you could also explain what OG means you’ll be a legend. I cannot get any answers on this) and the other is 925 with a capital M inside a diamond, the M is fully inside and doesn’t touch the edges of the diamond. The closest makers mark I can find is Marathon Co but it is slightly different. Thanks so much for your time!

      Hello Dawn,

      Regarding the 925 ring you got from your grandfather which is stamped 925 CHINA OG and is signed with a capital M inside a diamond shaped border or otherwise marked with the letter M enclosed within a diamond, we reply is follows.

      The 925 stamp represents the millesimal fineness mark for silver. This means the maker is claiming the ring is 92.5% silver.

      CHINA or 925 CHINA is a location mark and means the ring is manufactured in China, PRC.

      OG in the context of your ring most likely means Overlay Gold, often referred to as rolled gold plate or RGP. The OG marking is not likely to be strictly correct as stamped here because Gold Overlay is done by forging a new alloy with a base metal like brass, copper, an alloy of copper or silver core. Given the 925 base and the two color tones visible your ring is more likely to be GP (gold plated) or Gold Vermeil, which has sterling silver as the base material, plated in at least 10k (10 karats) gold and have a thicker level of gold plating than typically found on GP rings. Strictly speaking the 925 OG stamp – if genuine – should be accompanied by another stamp indicating the gold purity fused to the base / core metal.

      We’ve looked at the photos you sent us and M stamp inside a diamond matches a later edition marking of Marathon Co of Attleboro, MA. (see photo below). Marathon Co which has been in existence in various guises since the early 1900’s uses various maker’s marks. In addition to versions of the M inside a diamond stamp / mark some of their jewelry uses MARATHON spelt out capitals. See below photo of a 14K GF Marathon stamp. A lot of Marathon Co jewelry is marked GF (Gold Filled).

      Finally, we don’t think the ring was your grandmother’s wedding band because the 1950’s / 1960’s relationship date you mention makes no sense. Perhaps this ring was a later replacement? We say this because both the 925 and CHINA marks are modern marks. The 925 stamp is rarely used before the mid 1970’s and China’s open door policy didn’t commence in scale for offshore manufacture / ODM / OEM of 925 jewelry until the 1980’s.

      Hello Gayle,

      You’ve asked what 925 Italy 7 means when stamped on a ring.

      One possible answer is that your ring is designed and / or manufactured in Italy using 925 silver metal content. 925 marks in Italy are usually contained within an oval cartouche. The 7 likely refers to the ring size. Italian ring size 7 roughly equates to a USA size 4.

      However, as your ring appears to lack an Italian silversmith makers mark it is also possible the 925 ITALY simply means the silver which is used in the ring is sourced from Italy and actual manufacturing is done elsewhere. If that’s the case the 7 stamp is more likely to reference USA size 7.

      Hello Joe,

      The marking on your ring is most likely to be SAI © 925, i.e. SAI followed by a copyright symbol located on the inside band of the ring, with 925 stamp usually adjacent.

      SAI © is the makers mark. The SAI jewellers mark belonged to Samuel Aaron Inc, of Mount Vernon, NY. The Aaron Group, founded as Samuel Aaron Jewelry in 1950 was a third-generation family run business that had expanded from a single jewelry store in New York into a true international operation with factories, partnerships and hundreds of employees in Mumbai, London, Hong Kong and Guangzhou, China. The Group was acquired by the Richline Group – a wholly owned subsidiary of Berkshire Hathaway in January 2017.

      Your ring stamped SAI 925 if it’s a 925 ring with diamond simulant such as cubic zirconia would likely have been marketed under the DIAMONLUXE brand and made in China (PRC) in the early 2000’s. The DiamonLuxe brand was widely distributed in the USA via large department store chains such as KOHLS. We include photos below of the SAI © 925 jewelry marking.
