It absorbs negative energy like a sponge. Through absorbing negativity, the stone can prevent unwanted energy from entering your home, mind, body, or spirit which gives this stone its protective quality. Common formations of Tourmaline are Dravite and Schorl. Dravite tends to be a browner shade, earthly and rich whereas Schorl is as the inky midnight shade of onyx.
