Nitecore GEM10UV ultraviolet flashlight to identify amber/diamonds

The NiteCore GEM10UV is a professional light to identify, inspect and investigate fluorescent gemstones. This light is a real must-have for jewellers and gemstone enthusiasts. The light is enhanced with an ultraviolet light which produces up to 3000 mW/365nm ultraviolet light. With the unique rotary switch the GEM10UV is infinitely adjustable between 3000 mW and 5mW. Perfect to check the authenticity or potential flaws or cracks in the stone. The LED light is located directly behind the lens to lose as little light as possible. This is great when you, for instance, are checking a diamond ring.

The light works with one 18650 or two CR123 batteries. With a fully-charged 18650 battery the light will function up to 500 hours in the lowest mode. In the highest mode you need to replace the battery after approximately four hours and fifteen minutes.

This light has an aluminium casing to make sure it weighs next to nothing and cannot overheat. The light feels great in hand and the controls are simple, even while wearing gloves. On the side of the GEM10UV you find a practical ruler.
