THE 411 ON DIAMOND SELECTION

Why Consumers Need to Know about GemEx and Light Performance

The way a diamond plays with light is called light performance.  We also call it the "GaGa Factor" because it's what makes a ring truly gorgeous. Consumers care most about the ring's brilliance, fire and sparkle; after all, it's what makes the ring stand out in a crowded room!

GemEx has a powerful, patented tool (BrillianceScope™ Analyzer) that measures the way your diamond reflects and refracts light. The trademarked GemEx^® Certificate shows the diamond's performance from five different light views and accompanies each GemEx'd stone.  The five light views simulate a diamond in motion, like it is worn in real life.
