#### 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
