About this tool
This estimator uses approximate price-per-carat tables derived from publicly available diamond pricing data (Rapaport-style ranges). Prices are adjusted for carat weight thresholds, cut quality, shape premiums, and the natural vs lab-grown distinction.
The output is a range (±15%) to reflect the real-world variance between retailers, certification bodies, and individual stone characteristics like fluorescence, table/depth percentages, and symmetry that this calculator does not capture.
For the most accurate pricing, always request a certified stone (GIA, IGI, or AGS) and compare listings from multiple vendors.
