Known as 'Fools’ Gold, Pyrite comes from the Greek for ”firestone” because it was believed that Pyrite, a sparkling stone, held fire in its core. Pyrite is an excellent energy shield, blocking out negative energy and pollutants at all levels, preventing energy leaks from the physical body and aura and deflecting harm. Pyrite is very fast acting and helpful for getting to the root of karmic and psychosomatic disease.
