Helvetic Diamond Exchange
We select the best certified diamonds available on the market, and we offer them to a select clientele at the Rapaport® Diamond Report price.

AN INNOVATIVE IDENTIFICATION SYSTEM
All of our diamonds' Gemological Certificates have a unique Quick Response Code (QR Code), generated and validated by our system.

The owner of the gem can, at any moment, recall the original purchase price, verify the current selling price as well as check the actual realizable value.
