AGS Labs to Issue Oval Cut Grade Reports

The American Gem Society Laboratories on Wednesday said it has begun issuing diamond grading reports with cut grades for oval cut diamonds.

This is the industry’s first cut grade for the oval cut, AGS Laboratories said.

“We are pleased and proud to announce the roll-out of this popular cut,” says Frank Dallahan, president and chief executive officer of AGS Laboratories. “The oval cut is very popular with consumers and the addition of a cut grade to the AGS Laboratories grading reports for oval diamonds will add more objective and useful information for consumers to make decisions.”
In 2005, AGS Laboratories released its Performance-Based Cut Grading System for both the round brilliant and the princes—the first-ever cut grading system for a fancy shaped diamond. Soon after, the Lab released a cut grade for the emerald shaped diamonds.

“The Lab continues its research into cut grade for fancy shapes, and more shapes are expected to come on-line soon,” Dallahan added.

The American Gem Society Laboratories provides diamond-grading reports based on the highest standards of diamond grading and offers the only scientifically peer reviewed, objective and repeatable cut grade method in the industry.
