Ancient magicians relied upon Black
Tourmaline, known as Schorl, to protect them from earth demons as they cast their spells.
Today this stone is still revered as a premier talisman of protection, a psychic shield deflecting and dispelling negative energies, entities, or destructive forces.
It guards against radiation and environmental pollutants, and is highly useful in purifying and neutralizing one's own negative thoughts and internal conflicts, and turning them into positive, usable energy.
Also known as Schorl, it encourages positive attitudes, good luck and happiness, regardless of the circumstances that you find yourself in.
If Black tourmaline contains Mica, that allows it to return negative energy back to its source.
