UV Colorscope – UV Lamp for Fluorescence Testing of Diamonds & Gemstones

The UV Colorscope Diamond Tester is a professional-grade UV inspection unit designed for accurate fluorescence testing of diamonds and other UV-sensitive gemstones. Built with a high-intensity 366 nm Blacklight Blue UV lamp, this device delivers powerful and consistent illumination for both transmitted and incident UV analysis.

Unlike traditional overhead UV testing, the UV Colorscope features a darkfield viewing system that enhances contrast and allows even low levels of fluorescence to be detected with precision. The integrated viewing cabinet blocks ambient light, enabling reliable testing conditions even in well-lit environments.

The dual UV exits—top and bottom—offer flexibility for different testing methods. The bottom viewing window allows gemstones to be examined directly in parcel papers, making it especially convenient for diamond sorting and grading workflows.

With flicker-free electronic operation, durable construction, and a long lamp lifespan of approximately 5,000 hours, this unit is designed for consistent, long-term use in gemological laboratories, jewelry workshops, and retail environments.

To ensure accurate fluorescence grading, consistent testing distance is maintained, and the use of master stones is recommended for comparison under reproducible conditions.
