How to Estimate Diamond Carat Weight

Diamond weight can be estimated from measurements using the formula: Carat = Length × Width × Depth × Shape Factor. The shape factor varies: round brilliant uses 0.0061, princess cut uses 0.0083, and emerald cut uses 0.0080. Measurements are in millimeters. This provides an estimate — actual weight may vary based on cut proportions.
