You love gemstones and want tools to learn more about them, but you don't know what to buy... The Jeweler's Tool Series was created to address such feedback.

This is a blacklight that KARATZ's gemologists use on a regular basis.
Blacklights are used for simple identification of gemstones, observing fluorescence, and distinguishing other characteristics revealed by blacklight.
Please try shining the blacklight on your own gemstones.
You might discover new colors you've never seen before, or make new discoveries.

The wavelength of this blacklight is 365nm.

※We have updated the blacklight specifications. As a result, this light now includes rechargeable batteries and a charger for convenient, repeated use.

We will include one rough stone each of Oil-in-Quartz, Ruby, and Spinel.
