Natural Diamond Assurance Protocol

Our specially designed Diamond Protocol ensures that you only source natural diamonds. This assurance is given by using several devices and methods. These methods inculde looking at the nitrogen diamond type differentiation, examining the luminescence properties and performing photoluminescence and raman spectroscopies. The different devices used for these tests are the D-screen, the M-screen+ and the DFI.

All diamonds are checked on their natural origin when arriving at our office before entering our stock, even when those incomming diamonds left our office just one minute ago. Each diamond size has its own protocol:

      1. Stones starting from 3.7mm (0,20ct) color range D to J are first checked with the D screen device.
      2. Stones ranging from 1 mm to 3.7mm color D to J are first checked with the M screen device.
      3. Stones smaller then 1mm and stones in color K to Z and referrals from previous 2 steps are checked with the DFI set up.


Don’t hesitate to contact us if you would like to receive more information about our protocol.
