If you are examining gemstones and minerals, you will be able to detect fluorescence with the ultraviolet light (UV). Real diamonds fluoresce under UV light. While this is not a litmus test to identify a diamond, it helps to classify stones that do not fluoresce, as non-diamonds. Fluorescence is also a way to detect heat treated stones.
Band of six LEDs emit a white light that is cool and bright, accurately revealing the brilliance of each gemstone. Direct illumination eliminates shadows.
