Valkynos Rechargeable Diamond Tester Pen with LCD Display & UV Light – Professional High Accuracy Gem & Jewelry Testing Tool for Diamonds, Easy-to-Use Electronic Selector for Novice and Expert
【Perfect for Novices and Professionals - Easy-to-Use Diamond Tester】 This diamond tester is designed for both beginners and professionals. Simply power on, press the tip against the gemstone and wait for a beep to know if it's a real or fake diamond. A real diamond lights up to 9 and emits an audible sound. No reaction means it's a fake or simulant like cubic zirconia (CZ). Get quick, accurate results every time
【Thermal Conductivity for Accurate Testing - Diamonds Moissanite & Gemstone Tester】 Our tester uses thermal conductivity to accurately distinguish real diamonds, moissanite, and other fake gemstones. Real diamonds and moissanite have distinct thermal properties, and the tester's probe will produce a high-frequency sound to confirm authenticity. This ensures reliable gemstone testing and avoids false positives when testing synthetic diamonds or other stimulants
【Adjustable for Carat Sizes - Easy to Test Small & Large Diamonds】 Adjust the tester's settings according to the carat size displayed on the screen. For diamonds over 1.0 carats, turn on one green light; for 0.5 carats, two lights; and smaller stones, three to four lights. This feature ensures accurate results without needing to know the exact carat weight
【High-Frequency Sound for Metals & Simulants - Accurate Testing Feedback】 When testing metals or simulants, the device emits a high-frequency sound due to the thermal conductivity similarity to diamonds. Ensure proper testing procedure and avoid testing on metal, skin, or water for accurate results
【Complete Testing Kit】 The kit includes 1 diamond tester pen, 1 USB cable, 1 testing platform, 1 user manual. This gemstone tester kit is ideal for home jewelers, diamond enthusiasts, and professionals, making testing diamonds, moissanite, and other gemstones easy and reliable
