Diamond Authenticity Testing
The International Institute of Diamond Grading & Research
These services fully test all goods to verify diamonds, identify synthetics and simulants, and then return them in tamper evident sealed parcels with clear labelling as to the nature of their contents.Our laboratories are in three global locations: Antwerp, Surat, and Maidenhead. At all our facilities, our experts use comprehensive analysis using a variety of different in-house and proprietary equipment to ensure that every diamond we assess is natural.
