Where can I buy GemEx certified diamonds?

The GemEx Certificate

With the GemEx Certificate, you know how your diamond performs. 

Each and every diamond has been scientifically measured for its Light Performance┬« certificate.  The Certificate lets you choose the most appealing combination of brilliance, fire and sparkle.  

The 5 diamond images on the front of the certificate are the actual images of the diamond that you own or are going to purchase.  These images from the BrillianceScope are used to evaluate the percentage of white light and color light that the diamond returns and the number of points of light that turn on and off as the diamond moves.  GemEx ensures accurate brilliance, fire and sparkle results by measuring every diamond at multiple light angles.   

The Bar graphs show how your diamond compares to all others in the world in each category.  If your diamond is round, it is compared to other round diamonds.  If your diamond is square, it is compared to square diamonds, etc.  GemEx developed the scales for each shape by measuring tens of thousands of diamond to determine the range of brilliance, fire and sparkle possible.  

The IdentiView image reveals the craftsmanship and symmetry of the diamond.  Use this image to positively match your diamond and its Certificate.
