Valkynos Diamond Tester Kit with 60X Loupe & UV Light, Thermal Conductivity

Features

• FAST & ACCURATE DIAMOND TESTER KIT-- This professional diamond tester pen uses advanced thermal conductivity technology to accurately identify real diamonds and distinguish them from common simulants such as cubic zirconia, glass, and crystal. Ideal for home users, collectors, resellers, and estate jewelry inspection.
• IMPORTANT LIMITATION NOT FOR MOISSANITE-- This tester works based on thermal conductivity and cannot reliably distinguish moissanite, which has similar thermal properties to natural diamonds. Designed for basic diamond authentication, not electrical conductivity testing.
• TEST SMALL & MOUNTED DIAMONDS-- Accurately detects diamonds as small as 2 points (0.02 ct). Suitable for testing loose stones and mounted jewelry such as rings and earrings. For best results, avoid metal interference when testing set stones.
• UV FLUORESCENCE & CLEAR INDICATORS-- Built-in 365nm UV light provides additional reference by revealing fluorescence in some diamonds. Bright LED indicators and audible alerts deliver fast, easy-to-read results, making testing simple for beginners and professionals alike.
• COMPLETE & PORTABLE TESTING KIT-- Includes diamond tester, a 60X magnifying loupe, protective carrying case, and 9V battery includedready to use out of the box. Compact and travel-friendly. Backed by 30-day unconditional return or exchange and responsive customer support.
