RAPAPORT... Mumbai's Bharat Diamond Bourse (BDB) is considering allowingsynthetic-diamond trading on the exchange premises, its president told RapaportNews this week. Some members have asked management to reconsider its 2015ban on selling lab-grown diamonds anywhere in the BDB's vast office complex,Anoop Mehta said. The bourse will consult with members after the Diwalivacation season, and could call a vote in the first quarter of next year, he added. "One of the prime reasons [for outlawing lab-grown diamonds]was that detection was a major problem at that time," Mehta explained. "Detectionhas come a long way, so we will relook at it." Most diamantaires are unlikely to back the change as itwould damage their business, according to a trader at a member company, who wasnot aware that the matter was on the table. The bourse expects to brief members in informal meetings inDecember once traders have returned from Diwali, Mehta said. It will also usethose events to discuss the issues and ensure voters make an informed decision,he added. The BDB declared the bourse a "natural-diamond zone" inOctober 2015, claiming it was the first exchange to do so.
