American Gem Society™ Granted Three Patents

FOR IMMEDIATE RELEASE
AMERICAN GEM SOCIETY™ GRANTED THREE PATENTS
Recognition follows years of research on diamond cut grade
LAS VEGAS - The American Gem Society™ announced today that it was recently granted three patents from the United States Patent and Trademark Office (USPTO); they are the first in the trade organization's 74-year history.
The patents recognize the AGS Performance-Based Cut Grading System, which was developed by the American Gem Society Laboratories® Cut Grade Research team after years of research.
"We are thrilled with this acknowledgment of the American Gem Society's longtime research and leadership in the arena of diamond cut grade technology," said Ruth Batson, executive director and CEO of the Society.
"Peter Yantzer [AGS Laboratories' executive director] and his team of researchers have worked for several years to ensure the American Gem Society helps provide the trade with better-performing diamonds - and consumers with the confidence they're purchasing the most beautiful diamonds possible within their price point."
The first patent, number 7,336,347, was granted on Feb. 26, 2008 and recognizes computer ray tracing technology that helps determine a gemstone's light performance. This includes the AGS Performance Grading Software® and Angular Spectrum Evaluation Tool (ASET®).
The second - patent number 7,355,683 - was issued on April 8, 2008. It relates to systems and methods that, according to the abstract, "can be used to determine the dispersion of a diamond relative to an observation point, which can then be used to provide a map or other indicator" of the gem's fire potential.
Patent number 7,372,552, granted on May 13, 2008, recognizes systems and methods that illuminate a diamond with multi-angle, color-coded light rays in order to determine the location from which the gem gathers light.
The American Gem Society began researching its diamond cut grade methodology in 2000 and began delivering the new technology on its Laboratory reports in 2005, with the introduction of its Performance-Based Cut Grading System. American Gem Society members and AGS Laboratories use this system to assess cut grades on round brilliant, princess, emerald, and oval cuts; Batson said additional fancy shapes will be available from AGS Laboratories in the future.
