Diamond Grading Laboratory- AGS Laboratories Home Page
There are certain things you can count on. A quality grading report from AGS Laboratories is one of them. Its always reassuring to have the opinion of an expert unbiased third party who can verify the quality of the diamond you are purchasing. AGS Laboratories can give you that assurance. Grading is not just our business at the American Gem Society Laboratories. Its our mission: we were established to protect the consumer. Thats why we are the only grading laboratory to offer a unique zero to 10 grading system that provides easy-to-read clear and accurate information about each diamond we grade. With an AGSL grading report you are assured that youre buying an appropriately valued product graded with the gemological industrys highest standards of evaluating the 4 Cs: cut color clarity and carat weight. So even if your stone is not the benchmark of excellent quality the triple zero youll know that the value equals the quality. Thats the kind of assurance a grading laboratory should always give. It is the AGS Laboratories practice.
