The Weight of a Oval Brilliant Diamond calculator computes the approximate carat weight of an oval brilliant shaped diamond using the length, width, and depth of the diamond and a girdle thickness factor.

INSTRUCTIONS: Choose units and enter the following:

• (L) Length (measurement across the face of Oval Brilliant diamond)
• (W) Width (perpendicular measurement from length)
• (D) Depth
• (GTF) Girdle Thickness Factor:  This is a factor of the girdle  (middle) of the diamond. 

Oval Brilliant Diamond Carat Weight (W): The calculator returns weight of the diamond in carats.  However, this can be automatically converted to other weight units (e.g. grams) via the pull-down menu.
