This is the same black light that Caratz's gemologists use on a regular basis.
Black lights are used for simple identification of gemstones, to see fluorescence, and to identify other characteristics that can be seen under black light.
Try shining a black light on your own gemstones.
You might see it change into a color you've never seen before or make a new discovery.

The wavelength of this black light is 365nm.

*We have changed the specifications of the black light. Accordingly, this light comes with a rechargeable battery and charger that can be used repeatedly.

We will send you one stone each of three types of rough stones: oil in quartz , ruby, and spinel .
