Quickly and accurately distinguish genuine diamonds from imitations with the Diamond Selector II. This compact, pocket-sized diamond tester is an essential tool for jewelers, collectors, and gemstone enthusiasts. Using advanced thermal conductivity testing, it provides fast, reliable results with both LED light and sound indicators.

⚡ How it works:

• Genuine diamonds and moissanites trigger a clear sound and a full LED signal.
• Non-diamond materials show no sound or maximum indicator response.

💡 Features:

• LED indicator lights for visual confirmation

⚠️ Important Notes:

• This tester identifies diamonds and moissanites but cannot distinguish between them.
• It does not distinguish synthetic diamonds (lab-grown) from real ones.
• It does not test hardness even as the chart is up to 10. It can not be used to identify other gemstones.
• For moissanite-only detection, a specialized moissanite tester is required.
• Do not touch the probe tip during use, as it heats up.

✅ A practical, beginner-friendly tool for anyone handling gemstones. Keep one on hand to avoid costly mistakes when buying or testing diamonds.
