Calculation Notes

Round diamond weights are approximate and are based on the supplied round-diamond size chart. Exact 0.1 mm selections are mapped to the corresponding size band.

For Round diamonds, 5.9 mm is calculated at approximately 0.80 ct, 6.0 mm at 0.85 ct, and 6.1 mm at 0.90 ct.

Fancy-shape measurements and approximate carat references are based on the supplied layout measurement chart.

When the reference chart provides a carat range, this calculator preserves the range and calculates a minimum-to-maximum total.

Actual diamond weight can vary because of proportions, depth, girdle thickness, cut and manufacturing tolerance. Use this calculator for approximate planning only.
