KurtHeckman.Diamond - Round Brilliant

The Round Brilliant Diamond Weight calculator computes theRoundBrilliant.png approximate weight of a round brilliant shaped diamond based on the average diameter (vertical and horizontal can be entered in case the diamond face isn't precisely circular), depth and girdle thickness factor.

INSTRUCTIONS: Choose units and enter the following:

  • (L)  Vertical Length:  This is one measurement across the face of the Round Brilliant diamond.
  • (W) Horizontal Width: This is a perpendicular measurement from the vertical length and can differ in case the diamond is not symmetrical.
  • (D) Depth:  This is the depth of the diamond
  • (T) Girdle Thickness Factor:  This is a factor of the girdle  (middle) of the diamond.  Uses the pull-down menu to select the appropriate girdle factor.

Carat Weight (Wt): 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.
