Synthetic Diamonds Alert

Martin Rapaport the influencial publisher of the Rapaport Diamond Report today issued a Lab Alert that there are persistent reports and evidence that synthetic diamonds are being mixed into parcels of small (melee) diamonds.

Detecting synthetic diamonds is a challenge for gemmologists and jewellery valuers, especially when they are set into items of jewellery. Therefore the focus should be on protecting the supply chain – ensuring parcels of diamonds and diamond jewellery being imported in to New Zealand are identified correctly.

As yet there has been no evidence of small synthetic diamonds being salted into parcels of natural diamonds in jewellery sold in NZ. However local jewellers should be asking all overseas suppliers of finished diamond jewellery, or of loose diamond parcels to state on their invoices only contain “natural, untreated” diamonds. They should also seek random independent testing from gemmologists.
