One of the six precious O-Gems in Junk Jack. This ore can be found deep underground, along with the other five precious O-Gems.
On its own, this O-Gem can create O-Cut Amethyst.
This particular Gem's power, when Encrusted and in its O-Cut Amethyst form, is to increase the power of the O-Tool it is encrusted into.
