Diamond Tutorial: What is Table Percentage?

This is the final Diamond Tutorial for October, I hope the information and thoughts we’ve provided through the month have helped in some way. One last lesson today concerns ‘Table Percentage’

Diamond Tutorial: What is Table Percentage?

Table Percentage: This is the value representing how the diameter of the table facet compares to the diameter of the entire diamond. As such, a diamond that shows a 50% table has a diamond table which is 50% as wide as the outline of the diamond. Professionals in the industry calculate the actual table percentage by dividing the diameter of the “table” (measured in millimeters) by the average width (or girdle) diameter. Popular confusions are that a small table percentage (50% to 53%) does not make a round diamond any more brilliant than a diamond with a larger table.
