The Best of Excellence

Kwiat Tiara™ Diamonds are brighter, appear bigger and always receive the GIA's Excellent Cut Grade. But not all Excellent Cut Grade diamonds meet Kwiat's standards and earn the Kwiat Tiara™ Logo.

The GIA has published a series of charts to help diamond cutters understand what combination of diamond angles and proportions will earn the Excellent Cut Grade. This is one such chart.
