Advanced Cut and Price Analysis for Round Cut Natural Diamonds

Retail Diamond Price Report for September 8th, 2025

Prices in this report reflect the asking price that a retailer would always be prepared to accept for a single diamond, paid via cash or wire, including worldwide, insured, overnight shipping and "no questions asked" free returns with a seller-provided insured shipping label.

You should never pay more than this, and you can definitely pay less. However, the very best cut diamonds within the specifications will likely cost close to these amounts.

Only round natural diamonds for sale on this date with the following specifications are included in the calculation:

  1. Graded by Gemological Institute of America (GIA)
  2. Cut, Polish, and Symmetry all graded "Excellent"
  3. Depth >= 58.5° and <= 63.5°
  4. Table >= 55% and <= 62%
  5. No Fluorescence
  6. No "Extremely Thin", "Extremely Thick", or "Very Thick" Girdle
  7. No ".00" sizes for 1.00 carats and larger
  8. At least 0.3 carats
