How does the CutGrade calculator estimate diamond prices?

CutGrade uses the 4Cs (carat, cut, color, clarity) with market-weighted multipliers to create an independent price estimate. It is a guide for comparison, not a certification or grading service.

Which diamond characteristics impact price most?

Cut and carat weight have the largest impact on diamond price. Cut affects brilliance and can change price by 15-30%. Carat weight increases price exponentially. Color and clarity have less impact but can be optimized for value.

What 4C combination gives the best value for a diamond engagement ring?

The best value combination for a diamond engagement ring is: Excellent or Very Good cut (never compromise on this), G or H color (near-colorless, 20% savings over D-F), VS2 or SI1 clarity (eye-clean at lower cost), and slightly below common weight thresholds (0.9ct instead of 1ct saves 15-20%). This combination delivers luxury appearance at significantly reduced cost.

Q: Is CutGrade affiliated with any grading lab?

Q: What is a good price for a 1 carat diamond?

A good price for a 1 carat diamond ranges from $3,000-$8,000 for natural diamonds with G-H color and VS2-SI1 clarity. Lab-grown 1 carat diamonds of similar quality cost $500-$2,000. Round brilliant cuts command a premium; fancy shapes like oval or cushion cost 20-30% less.

Q: Should I buy a lab-grown or natural diamond?

Lab-grown diamonds cost 50-70% less than natural diamonds of identical quality. They are chemically identical, just as hard, and have the same brilliance. Natural diamonds have better resale value. For maximum beauty per dollar, lab-grown diamonds offer exceptional value. For long-term investment or tradition, natural diamonds are preferred.
