鑽石、莫桑石及白藍寶石測試儀 - GEMORO的TESTEROSSA

Took me a few tries to get the hang of the sensitivity dial, but once I did, it instantly distinguishes my loose moissanite from my diamond ring—no more confusion. The thermal conductivity feature feels fast and reliable, and the UV mode really seals the deal on identification.

The UV-F1 moissanite mode caught a stone my old tester flagged as diamond—turns out it was moissanite, so this thing really earns its keep. I've run it on sapphires, CZs, and a few genuine diamonds, and the readings were spot-on every time. It's given me way more confidence buying loose stones onlin

The UV-F1 moissanite detection feature works perfectly—tested it on a few loose stones and it identified every single one correctly. My jeweler was impressed when I brought in a ring I was unsure about. For anyone buying secondhand jewelry, this tester pays for itself quickly.
