- 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. Note: Only valid for gemstone testing—non-diamond items cause incorrect readings
- VIDEO GUIDE INCLUDED : Step-by-step operation & troubleshooting video covers preheating, calibration, perpendicular alignment, solves 90% of usage issues. Skipping any required steps may lead to inaccurate detection results
