Professional Gem Jewelry Tester Identification Tool, High Accuracy Jewelry Diamond Tester,for Jade Jewelry Diamond Moissanite

Product Features lamps have two wavelengths and a light switching button, making it easy to switch between long and short wavelengths. There is a color filter at the lamp head, which only allows effective ultraviolet light to pass through. The dark box has good shading effect, and no external light enters the dark box during use. The eyepiece of the dark box is small and has a wide observation range. Gemstones of any color, luster, transparency, or shape can be observed using ultraviolet lamps Instructions for use Step 1: Clean the gemstone, place it on the black background of the lamp gemstone compartment, and close the gemstone compartment lid. Step 2: Keep your eyes close to the observation window, allowing them to adapt to the gems in the gem chamber, and pay attention to the influence of surrounding lights, so that the gems are completely in the dark. Step 3: Turn on the power switch of the ultraviolet lamp and wait for a moment (waiting for the emission of ultraviolet light). Press and release the LW button for 2-3 seconds, and the long wave ultraviolet light will turn on. Observe the fluorescence color and intensity of the gemstone and record it. Then press the SW button for 2-3 seconds and release it. The shortwave ultraviolet light will turn on, observe the color and intensity of the gemstone, and record it. After observation, turn off the light.

• Professional Jewelry and Diamond Identifier: Equipped with both 365nm long-wave (LW) and 254nm short-wave (SW) ultraviolet wavelengths, it can comprehensively stimulate the fluorescence reaction of different gemstones. Easily switch between dedicated green (LW) and red (SW) buttons to meet the needs of professional gem identification for comparative analysis of fluorescence color and intensity.
• The darkroom provides excellent light-blocking, completely isolating external light interference and creating a pure black observation environment. The lamp head is equipped with a high-quality color filter to filter stray light, ensuring only pure and effective ultraviolet light passes through, thereby guaranteeing the accuracy and reliability of fluorescence observation and avoiding misjudgment.
• The device integrates a power switch and wavelength switching button, making operation intuitive and simple. The observation window (eyepiece) is scientifically designed, ensuring not only a wide field of view but also allowing the eye to comfortably approach the window, facilitating the detector's focus on the details of the fluorescence reaction within the gem chamber, thus improving identification efficiency.
• Wide Applicability and Standard Operating Procedures: Suitable for gemstones of any color, luster, transparency, and shape, offering strong versatility.
