AGS Graded Loose Diamonds
AGS, also known as American Gemological Society, is located in Las Vegas. The AGS diamond grading scale is considered to be as stringent and consistent as that of GIA. AGS was the first diamond grading laboratory to come out with a cut grading system for the round brilliant diamond, modeled on the mathematical formula designed by Marcel Towlkowsky. Known by AGS terminology as “Ideal” cut, these round cut diamonds are designated as such according to face up light performance, ideal symmetry and ideal polish.
In an effort to measure a diamonds light refraction and face up light performance, AGS researchers introduced the ASET scope technology, which pinpoints and reports a diamonds light refraction, distribution, and intensity. Combined with a personal evaluation by an experienced and knowledgeable diamond vendor, consumers shopping for diamonds can gain an extra measure of confidence that they are purchasing a high-quality diamond.
