The value of a diamond is primarily determined by the four Cs: cut, color, clarity, and carat, with cut having the biggest impact on visual beauty and perceived value. Weigh cut first for brilliance, then color and clarity depending on your budget and viewing distance; carat increases price exponentially, so balance size with quality.
Key Facts
- Cut affects sparkle most; an Excellent/Ideal cut looks brighter than a larger poorly cut stone.
- Color and clarity influence appearance until certain thresholds (e.g., H color often appears near-colorless to most observers).
- Price per carat increases non-linearly; doubling carat weight often more than doubles price.
- $3k–$7k: ~0.5–1.0 ct, VG–E cut, G–I color, VS2–SI1 clarity
- $8k–$15k: ~1.0–1.5 ct, Excellent cut, F–G color, VS1–VS2 clarity
Summary
Cut is the most important factor for beauty; balance color, clarity, and carat to match your visual goals and budget. Use certification (GIA/IGI) to confirm specs.
