In partnership with the GGTL Diamond Laboratory based in Liechtenstein and Geneva, Cullinan Diamonds provide a CULLINAN DIAMOND REPORT™ for their quality diamonds.
The Cullinan Mark
Having a diamond with the CULLINAN DIAMONDS™ seal of quality combined with the unique identification of the CULLINAN DIAMOND REPORT™ is the pinnacle in diamond quality for one of the most precious and unique treasures in which we can participate in the time and history of our planet.
Mark Cullinan (MRC) and Cullinan Diamonds (CD) have hallmarks registered in the London Assay office and the Edinburgh Assay office for the hallmarking of gold, silver and platinum with the relevant assay markings. These markings certify the purity of the precious metals used. They are also compliant with National and International regulations.
