Mineralogy: Tourmaline is not a single mineral, but a group of several closely related minerals. The most common of these minerals almost exclusively occur in granite pegmatites. Tourmaline is both pyroelectric and piezoelectric. If a specimen is put under a pressure or temperature change, it will generate an electrical charge. When this happens, dust particles become attached to the crystal ends.
Metaphysical Properties: Black Tourmaline is a purifying stone that deflects and transforms negative energy. A potent protection stone used to ward off psychic attack or cleanse negativity from the aura. Excellent for grounding excess energy, Black Tourmaline also deflects harmful cell phone and electromagnetic radiation.
