Las Vegas—The American Gem Society's (AGS) new Performance-Based Cut Grading System has received its fourth patent, the AGS announced.

Issued by the United States Patent and Trademark Office (USPTO), the patent, No. 7,382,445, is for "methods for grading gemstones, apparatus for grading gemstones and systems that utilize such methods and apparatus," according to the patent's scientific abstract.

AGS Laboratories Executive Director Peter Yantzer and his team developed the patent, which was granted on June 3.

"It's certainly exciting for us to receive another patent. It's a wonderful acknowledgment of the work performed by the AGS Laboratories research team," AGS Executive Director and CEO Ruth Batson said in a media release. "But the motivation behind our research is, and has always been, to contribute to the body of gemological knowledge in a way that enriches and protects the jewelry industry and its consumers."

The announcement follows the AGS' recent news that in the first half of 2008 it had received three patents for its new cut-grading system, a first for the organization.

Those patents—Nos. 7,336,347, 7,355,683 and 7,372,552—are on file, along with the fourth patent, with the USPTO.
