Traditionally, once they are shaped, but before they are mounted, diamonds are rated by the “4 Cs” — clarity, color, carat, and cut. Modern gemology, however, grades finished diamonds by a more accurate standard: light performance. The quality of how a diamond innately captures and “plays” with light separates a superior gemstone from a flawed one. Supporting 10 million people and recording a profit of $1,010 billion in 2006, but facing a global supply crunch and competition from gem-quality synthetic diamonds, the diamond industry must get superior stones on the market quickly and reliably. For quality assurance, many firms have turned to the BrillianceScope™ Analyzer from GemEx (Mequon, WI) to measure the light performance of finished diamonds in a comparative test against some of the industry’s highest-rated stones. GemEx utilized the RGS™ Rapid Guide Screws from Kerk Motion Products (Hollis, NH) to maintain the precision of the BrillianceScope’s testing mechanism.
