Black Tourmaline will absorb any negative energy in its vicinity and is also an excellent grounding crystal. Tourmaline produces the most energy of the Piezo Electric stones, which also include Quartz & Topaz. Therefore it will almost constantly emit an electrical current and the energy output will be increased if the Crystal is stimulated in any fashion (via thought, touch, etc.), and the energy will be significantly more intense than with a Quartz stone.
