Its natural white light helps to look at inclusions, a perfect light for viewing diamonds and other gemstones. It also have achromatic optical glass magnifier for better viewing result, metal body, UV light (long wave) for some stones that fluoresce under UV. Triplet magnifiers are our best quality geology lenses!
