De Beers Group submitted four diamond verification instruments (DVIs) for Assure testing and all received “excellent results,” the company reported.

The Diamond Producers Association[2] (DPA) and Signet Jewelers[3] have jointly launched Assure, an independent program to measure the performance of lab-grown diamond detectors.

Through the Assure Directory, traders can access third-party-verified information on the relative performance of diamond verification instruments (DVI), as well as guidance on how to ensure their business is protected from undisclosed laboratory grown diamonds.

“Trade participants have a shared responsibility to disclose the nature of the product they are selling to protect the end consumer,” said Jean-Marc Lieberherr, DPA’s CEO. “Through the Assure Program, we will support the diamond trade, from independent jewellery retailers to large diamond manufacturers, to make informed decisions on how to ensure undisclosed laboratory grown diamonds do not enter their natural diamond supply chain.”

The project partnered with 11 manufacturers representing the 18 most widely available DVIs on the market, which were then tested with a “deliberately challenging” sample, according to the DBA.
