This black and chrome loupe has six built-in LED lamps around its lens that light all sides of the piece equally. The 5500 Kelvin white light—the same light used in a gemstone grading lamp—provides a brighter viewing area and clearly shows the brilliance of each gemstone. With the flip of a switch, the entire LED ring emits a longwave UV light suitable for fluorescence testing for coins, rocks, currency and more! Or you can select just the LED when you don’t need the UV. The three bonded lenses (triplet) are highly corrected for spherical and chromatic aberrations, producing a sharp and distortion-free image. Each loupe comes packaged in a snap-close leather case and a gift box.
