Diamond Identification Report

2 carat round brilliants ready for diamond identification reports

An identification report documents everything visible about a diamond without using destructive testing. Each natural diamond has a colour grade, transparency level, cut style, dimension and vibrancy.

Various inclusions and nicks on a stone may be natural or created by buyers, wholesalers and diamond cutters. Marks that are visible with a 10x loupe display the way a diamond travelled through the diamond world to TrefuGems and are marked on the identification report as a mark added in transit to TrefuGems.


Diamonds that are cut by a gem cutter and then giving directly to a client may not have these industry marks and will require an identification report to start the diamond’s provenance.
