Black Tourmaline Chunk
"Black Tourmaline protects against 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, Black Tourmaline promotes a laid-back attitude and objective neutrality with clear, rational thought processes. It encourages a positive attitude, and stimulates creativity.
