Weight (Carats) = Length (mm) × Width (mm) × Depth (mm) × Coefficient
- Length: Longest dimension (mm)
- Width: Widest dimension (mm)
- Depth: Height from top to bottom (mm)
- Coefficient: A specific factor based on the diamond's shape and cut.
Our calculator uses industry-standard coefficients for various diamond shapes to provide the most accurate estimation.
