Gemex Brilliance Technology


Glennpeter Jewelers & Gemex Systems, Inc. — Using advanced optics to take the guesswork out of diamond buying!

The Science of Beauty — GemEx technology makes it easy to buy the right diamond. 

GemEx Systems, Inc. is a company committed to applying the latest in digital optics technology to the worldwide diamond industry. The industry has often been accused of applying highly subjective (and often confusing) standards to determine a diamond's value. GemEx represents a new approach to determining diamond quality. For both consumers and the industry, the solution is technology. Consumers can access this technology free of charge through a rapidly expanding list of qualified jewelry retailers.

Why should I care about GemEx and Light Performance?
When you shop for a diamond you would like a beautiful diamond that gets noticed in a crowd and that you can be proud of. What makes a diamond beautiful and gets noticed is the way it plays with light, or the Light Performance.
The traditional 4C information does not help you to separate a beautiful diamond from a diamond of inferior appearance. Three of the 4 C's, Color, Clarity and Carat weight have very little effect on the appearance of the diamond. These 3C's determine the rarity of the diamond. The 4th C' cut does affect the appearance, but it is not well defined and it ignores the light characteristics of the diamond material. Even so called "ideal cut" diamonds do not guarantee you great light performance.

GemEx is independent and objectively measures the light performance and allows you to compare it to every other diamond in the world. It is easiest and surest way to choose a diamond that you will be proud of for eternity.

GemEx invented the concept of measuring the light performance of diamonds, and patented the instrument that measures it. Others have tried to copy GemEx, but a reliable light performance measurement is nearly impossible without violating the GemEx patent. Only GemEx measures each and every diamond, reviews and validates the results of every diamond, and then provides you, the consumer, a reliable Light Performance Report.
