Harper ★★★★★

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.

Sofia ★★★★★

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

Michael N. ★★★★★

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.
