Black (Schori): Black tourmaline—which can, in reality, range from dark blue to dark brown to true black—is thought to be a grounding stone that provides a connection between the Earth and the human spirit. It is supposed to help people find a sense of self-confidence, see the world more clearly, and feel empowered during difficult circumstances. Ancient magicians reportedly used the stone to protect themselves from "Earth demons," and it's still thought to have protective properties.
