BLACK TOURMALINE - ROUGH STONE

The Science

Black Tourmaline is a silicate mineral that grows in prismatic columns. It can form from either molten rock or hydrothermal activity. In addition to its beauty, black tourmaline is an incredibly useful material. Its pyroelectricity, or ability to heat crystal and create a temporary electric charge, lends itself to being used in x-rays, LEDs, and even hair straighteners!
