The following tables are to be used to determine the stone's quality
of cut. Apply the 3 parameters from the "quality of cut" section
here to arrive at the correct cut grade. The final grade is based
on the lowest denominator. For example : If a round stone you checked
yielded two "goods" and one "fair", the price should be based on
the "fair". Or, if a diamond's girdle runs from very thin to extremely
thick it's cut grade should be based on the lower (extremely thick)
grade.
The following are the recommended total depth percentage, table
size percentage and girdle thickness for determining cut quality
for diamonds in the advanced comparison search.
