## 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. 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
- BATTERY INSTALLATION WARNING : Ensure the 9V battery is installed with correct polarity and properly seated in the battery compartment. Otherwise, the device may fail to power on. For details, please refer to the instruction manual

### ⭐ 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. Thank you
