Embee Diamonds uses AGS Laboratories to grade Sirius Star®...the world's brightest diamond® and have selected to offer a Properietary Platinum Diamond Quality® Document or Diamond Quality® Analysis to accompany each of its diamonds.
Working closely with AGS Laboratories's research department, a performance-based cut grade was developed for each of the Sirius Star® Diamond shapes. All the diamond's characteristics plus the patented computer-generated Light Performance map unique to each diamond are what make the Properietary Platinum Diamond Quality® Document the ultimate grading report.
AGS Laboratories uses a scientifically vetted cut-grading system, based on optical physics and the American Gem Society’s proprietary ray-tracing software. This three-dimensional analysis is the ultimate test for evaluating the performance of light in a diamond, which is the cornerstone of the Proprietary Platinum Diamond Quality® Document.
The AGS Diamond Quality® Analysis is a pocket-sized document for smalled diamonds. The Diamond Quality® Analysis offers a complete grading evaluation of the diamond's characteristics, and also includes the patented computer-generated Light Performance map unique to each diamond.
Each Sirius Star® Diamond (sizes 0.39ct+) is inscribed with its AGS Laboratories report number and the Sirius Star® logo.
