Each cut possesses different weights depending upon its size. To find its weight, multiply the length, width and coefficient value. Here we have mentioned the coefficient of all the diamond cut. Substitute the values in the diamond weight estimation formula and replace the coefficient value from the given value.


Diamond Carat Weight (D) = Length x Width x Depth x Coefficient


Round Brilliant Coefficient = 0.0061
Princess Cut Coefficient = 0.0082
Asscher Step Cut Coefficient = 0.008
Cushion Brilliant Coefficient = 0.00815
