Diamond giant De Beers’ International Institute of Diamond Grading and Research (IIDGR) subsidiary on Tuesday unveiled a synthetic screening device to test multiple stones in set jewellery at once without the need for a probe. Synthdetect, which also has a low referral rate of around 0.05%, uses the group’s patented luminescence technology to rapidly and simultaneously screen stones set in jewellery pieces, including rings, earrings, bangles, broaches and necklaces.
