Tourmalinated Quartz is clear rock crystal (crystal quartz) which has grown together with black tourmaline, and shows strands of the tourmaline running through the quartz, hence "tourmalinated.". The earliest use of tourmalinated quartz was for tools made by hominds in Ethiopia over 2 million years ago.
