Understanding the AGS Light Performance Diamond Quality Document

The Light Performance Diamond Quality Document (DQD) available from the American Gem Society Laboratory (AGSL) is the most complete diamond grading report available at this time.  This tutorial describes the various sections of the DQD and provides detailed insight which will help you make a better diamond buying decision.  The Light Performance DQD pictured above is for a 1.380 carat, F-color, VS-1 clarity, Hearts and Arrows Diamond from the Brian Gavin Signature Collection, it’s got me drooling!
