De Beers Group Industry Services is proud to offer ground-breaking, low-cost testing services designed to strengthen confidence in diamonds.
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.
Consumer confidence is at the heart of everything we do. Our fundamental promise of accuracy, knowledge and expertise allows us to stand confidently by our results. Our 130 years of diamond expertise ensure the quality of our service is the best in the business.
