Certified Diamonds

“Ever since I purchased my first GemEx certified ring, I have not bought any more diamond jewelry without it! I am truly convinced that diamonds bought without a GemEx certificate aren’t worth the other papers that diamond may have.”

Stephanie Karen Munn – Diamond Consumer

Why certification matters

When shopping for a diamond you can make your dollar go further by trading rarity for size and beauty. Diamonds are priced based on the 4C’s: Color, Clarity, Carat Weight and Cut. But this information doesn’t help you differentiate between a beautiful diamond and a diamond with inferior brilliance, fire and sparkle.

Light Performance

The GemEx Certificate

With a GemEx Certificate, you know exactly how your diamond performs in real life lighting situations. The Certificate lets you choose the most appealing combination of brilliance, fire and sparkle.
