AGS Diamond Quality Document

Why It’s Great

The AGS Diamond Quality® Document (DQD) is the first grading report to offer a complete analysis of the 4Cs, including cut, from a premier diamond grading Lab. Cut can affect the value of a diamond by as much as 50% or more; that's why this document is important.

The DQD provides you with the most detailed information available on a diamond. Plus, the Diamond Quality® Document is the industry’s only grading report that offers a three-dimensional performance-based cut grade for the Round Brilliant, Square Princess, Emerald, Oval and Cushion-shaped diamonds. The Diamond Quality® Document is also offered in a “Platinum” option.
