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, 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, real fluorescence phenomena and precise gemstone judgment. Testing materials and applications: Identifies amber beeswax by its blue, or purples fluorescence; detects glued jadeite, dyed gemstones, and bleached pearls through abnormal fluorescence; and assesses diamonds or moissanite based on specific fluorescent properties under light. Humanized design for ease of use: Offers stable, flicker-light to protect eyes and ensure comfortable observation, with large-sized eyepieces and independently controllable long wave and short wave switches for flexible operation based on gemstone size and type. 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 safety and test accuracy.
