Black Tourmaline is one of the most common meditation crystals. Potent, inky black, and with strong grounding forces, this jet colored stone is known for being a swallower of negative energies.
Place black tourmaline near your bed or in the corner of a room, for amplified protection for you and your space. Carry it with you in your pocket for extra protection while in public or at work. Wear jewelry that has black tourmaline in it, such as a bracelet or necklace as well.
