Gemstone Tester, a Professional Jewelry Testing Tool, Uses Both Long and Short Wavelengths to Identify Jadeite, Diamonds, and Moissanite.

Specifications: Name: Professional Jewelry Tester Identification Tool Power: 7W LW: 365 nanometers SW: 253.7nm Material: Metal casing Function: Observe gemstone phenomena under ultraviolet radiation Size: 190x180x230 mm Weight: 3.5KG Product List: 1* Diamond Tester Set

• Dual-band light source for professional gem identification: This advanced device features two specific wavelengths—365 nanometers (long wavelength) and 253.7 nanometers (short wavelength)—that effectively excite fluorescence in a variety of gemstones.
• Integrated anti-interference design ensures accurate observation: The device features a robust metal casing with a built-in light shield, significantly reducing ambient light interference.
• Multi-functional detection: It can also effectively evaluate jadeite and other gemstones, revealing abnormalities in treated gemstones (such as bonded jadeite, dyed gemstones, and bleached pearls) through unusual fluorescence reactions.
• Edible design: The device provides stable, flicker-free illumination, protecting the user's eyesight even during prolonged viewing. It is equipped with large eyepieces and independently controllable long/short wavelength switches, allowing for flexible adjustment according to the specific size and type of gemstone.
