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:
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.
The common gem cutsthat are specific to diamonds and diamond cuts including the following:
The equations and data used in vCalc's jewelry library and calculator were reviewed by a certified gemologist. The equations are based on industry recognized formulas and data. The table below shows a comparison of computations between vCalc and an industry accepted application (Quantum Leap).
The length, width and depth are in millimeters (mm), and the Quantum Leap and vCalc measurements are in carats (cwt).
The largest variance, an oval faceted alexandrite, which can be seen in the last row above, has been double checked against several source equations which tend to support vCalc's accuracy.
