I have to say, this is my favorite stone for psychic protection and grounding! I always have to have one nearby. Black Tourmaline keeps an electric charge due to its pyroeltric features (meaning it can generate electricity when heated), as well as piezoelectric (meaning it can store an electrical charge), causing it to release negative ions and far infrared radiation- all of which are very beneficial for health. This incredible stone is associated with protection, grounding, health, happiness, luck, and positivity. Black tourmaline has been used by Shamans and healers for protection for centuries. Black Tourmaline is considered by many to be the most powerful protective stone as well as famously providing healing on all levels - physical, emotional, mental and spiritual.
