Diamond authenticity at your fingertips: Whether you're a jewelry novice or an experienced jewelry enthusiast, this rechargeable diamond detector allows you to quickly and easily identify gemstones. Simply touch the pen to the gemstone, and the real diamond will beep and light up 9 indicator lights for instant and reliable results.

Advanced thermal conductivity technology: High-precision detection of real diamonds, moissanite, and fake gemstones. This detector uses advanced thermal conductivity detection technology to accurately distinguish between real diamonds and imitations such as cubic zirconia, eliminating costly guesswork.

Adjustable carat detection for increased accuracy: Customize your detection for different gemstone sizes. Easily adjust the carat range—from under 0.5 carats to over 1.0 carats—to get accurate readings whether you're testing small diamonds or large gemstones, without having to know the exact weight.

Intelligent audio and video feedback system: Equipped with a high-frequency sound alarm and a clear LCD display, this detector provides reliable feedback for every test. UV light helps enhance the visibility of the gemstone, and a built-in safety device prevents false readings due to metal or skin contact.
