220v Portable Gemstone Tester for Jewelry Identify Jade, Diamond, Moissanite & More Essential Tool for Jewelers & Gem Enthusiasts

This type of ultraviolet lamp is used to excite fluorescence, which is an important characteristic for identifying gemstones. It provides long wave and short wave light. Application: Used for detecting diamonds, colored gemstones, composite gemstones, jadeite, and other types of gemstones. Many diamonds or colored gemstones exhibit fluorescence under ultraviolet light. Colored jadeite (type B) bracelets typically exhibit strong fluorescence under ultraviolet light. Specifications: Name: Professional Jewelry Tester Identification Tool, Color: Black and white, Power: 7W, LW: 365 nanometers, SW: 253.7nm, Material: Metal casing, Function: Observe the phenomenon of gemstones under ultraviolet radiation, Size: 220x190x110 mm, Weight: 3.0KG. Matters and precautions: 1. Ensure to avoid the influence of ambient light when viewing gemstones. 2. If the gemstone is too large, you can turn off the LW or SW lights to view it, but remember to do so in a dark room. 3. Do not look directly at ultraviolet rays, please turn off the power after testing. note：This product does not support 110V voltage. Please do not place an order if the voltage is not compatible, otherwise you will need to provide your own transformer.

• Dual band ultraviolet light source for professional gemstone identification: This equipment provides two precise wavelengths, long wave 365 nanometers and short wave 253.7 nanometers, to effectively stimulate fluorescence reactions in gemstones, aiding in authenticity and processing detection for diamonds, colored gemstones, jadeite, amber, and more.
• Integrated anti-interference design for accurate observation: Features a metal shell and built-in shading box to isolate ambient light, with a filter that removes stray light, ensuring pure output for clear, real fluorescence phenomena and precise gemstone judgment.
• Testing materials and applications: Identifies amber beeswax by its blue, green, blue-green, or fluorescence; detects glued jadeite, dyed gemstones, and bleached pearls through abnormal fluorescence; and assesses diamonds or moissanite based on specific properties under light.
• Safe use guidelines and clear operating procedures: Advises users to avoid direct eye exposure to light, recommends testing in dark room environments, and emphasizes turning off power after use to ensure operational safe and test accuracy.
• note：This product does not support 110V voltage. Please do not place an order if the voltage is not compatible, otherwise you will need to provide your own transformer.
