Berkem Diamond Sure I/II Tester
The Berkem Diamond Sure I/II Tester is a handheld gemstone tester built to help you tell genuine diamonds and moissanite apart from simulants. It’s a handy tool for jewellery buyers, collectors, hobbyists and anyone who wants a quick second opinion on a stone.
A pocket-sized diamond tester gives you fast, on-the-spot readings so you can shop and evaluate with more confidence, and this one distinguishes between diamond and moissanite in a single device. As an open-box liquidation find it arrives in near-new condition well below regular retail, and since it’s one-of-a-kind, once it’s gone it’s gone.
