Mr. Atlas and his lab is known for its diamond cut grading system. The AGA 1A cut grade for round diamonds is even narrower than that allowed by AGS for its "0" cut grade, and the Accredited Gem Laboratory is, at this time, the only lab with a cut grading system for fancy shaped diamonds. Thus, the AGA cut grading charts are used as a reference tool for fancy shaped diamond proportions by much of the industry.
