DK91016 Diamond Lighting Box | UV 254nm & 365nm Fluorescence Tester with White LED Lighting
The DK91016 Diamond Lighting Box is a compact, professional gemological inspection instrument designed for accurate observation of diamonds and gemstones under controlled lighting conditions. It combines multiple white light modes with long-wave and short-wave UV fluorescence, making it an essential tool for gemologists, diamond graders, jewelers, and laboratories.
This lighting box provides reflected white light, side white light, top white light, and cross-cycle white illumination, allowing users to examine clarity, inclusions, cutting quality, and surface features. The integrated long-wave UV (365nm)and short-wave UV (254nm) enable reliable fluorescence testing, helping distinguish diamond characteristics and identify treatments or synthetic materials.
A built-in 10× magnification lens (30mm diameter) supports close inspection without the need for additional tools. The compact size and lightweight design make the DK91016 ideal for laboratory benches, retail counters, trade shows, and mobile gem testing. Powered by USB or AAA batteries, it offers flexibility for both stationary and portable use.
Designed with safety in mind, the short-wave UV function automatically switches off after two minutes to reduce exposure risks, ensuring safer operation in professional environments.
