Diamond Cut Information

There are many differing opinions regarding perfect cut proportions, each faction favoring its preferred combination of percentages of depth and table, vying over which mathematical formula makes a diamond most beautiful. The two most widely accepted "formulas" are the Tolkowsky model (widely recognized by a majority of the jewelry industry as the "ideal" proportioning for the modern round brilliant cut diamond) and the GIA 60-60 rule.

Tolkowsky Ideal Cut
Depth%
60.1-62.8%
Table%
53-57%
GIA "60-60" Rule
Depth %
58-63%
Table %
53-61%

These charts are intended as a basic guide to aid you in selecting the finest proportions. There are other technical factors that could be debated, but the percentages listed below are the ones we feel you should focus on. Remember, to fully understand the relationship between cut and proportions you also need to read the information we provided on fancy cut and round diamond cut guidelines. Depth and table percentages are important characteristics, but overall measurement is equally significant.
