Formula:

Diamond Carat Weight (D) = Length x Width x Depth x Coefficient Where, Round Brilliant Coefficient = 0.0061 Princess Cut Coefficient = 0.0082 Asscher Step Cut Coefficient = 0.008 Cushion Brilliant Coefficient = 0.00815 Heart Brilliant Coefficient = 0.0059 Trillion Brilliant Coefficient = 0.0057 Marquise Brilliant Coefficient = 0.00577 Pear Brilliant Coefficient = 0.00597 Oval Brilliant Coefficient = 0.00645 Emerald Step Cut Coefficient = 0.00993 Radiant Brilliant Coefficient = 0.00825

Example:

Calculate diamond weight for heart brilliant coefficient having length of 12 mm, width of 6 mm and depth of 18 mm.

Solution:

Diamond Carat Weight (D) = Length x Width x Depth x Coefficient
D = 12 x 18 x 6 x 0.0059
= 7.6464 cts
