Black Tourmaline (Schorl) protects against cell phones, electromagnetic smog, radiation, psychic attack, spells and ill-wishing, and negative energies of all kinds. Connecting with the base chakra, it grounds energy and increases physical vitality, dispersing tension and stress. Clearing negative thoughts, Schorl promotes a laid-back attitude and objective neutrality with clear, rational thought processes. It encourages a positive attitude, no matter what the circumstances, and stimulates altruism and practical creativity.
