Make a sound when its a real diamond. Doesn't work on other gems ## Features - ACCURATE DETECTION : Our professional diamond tester pen (a reliable gem tester) features a sophisticated sensor for precise gemstone identification (Diamonds/Moissanite: 9+ lights + beeps; Jade: 5-6 lights; Crystal/Glass: 5-7 lights). (Jewelry-Only Detection – Not for metal/gold or gold testing kit use) - STANDARD OPERATION : Insert battery (Gently press the wire and the cables to hold battery will secure it in place) → Power on → MUST preheat 30s (critical) → Adjust indicator to 4th mark (do not skip) → Hold back metal plate → Probe 90° perpendicular to gemstone. Reset to 4th mark before each test - METAL DETECTION NOTE : Not for metal/gold or gold testing kit use – metal has similar thermal conductivity to diamonds (normal beeping, not a defect). Consistent with title "Jewelry-Only Detection" - PACKAGE CONTENTS : Diamond tester pen + user manual + 9V battery + testing platform. Read the manual first to maximize accuracy with your diamond detector - PRECAUTIONS : Avoid windy/cold conditions (15-25℃ recommended); Keep probe perpendicular to gemstone; Turn off power after using this diamond checker - SEAMLESS SHOPPING EXPERIENCE : Useful usage guidance for this diamond tester and gem tester is available via included resources.

Make a sound when its a real diamond. Doesn't work on other gems ### ⭐ Gem tester was not good. You get what you pay for *by K***L on August 7, 2026* I was hoping that this diamond tester would work better, I tested several items & none were accurate. It is easy to use but the quality isn’t great. It’s a low price but you get what you pay for.
