Magnetite

This gray or dark brown stone is also known as lodestone, a poetic name I much prefer. It has a major quantity of iron and is, as the name implies, very magnetic. The ancients called it lodestone, although Plato himself wrote that it was the “heraclean stone.” All iron-based crystals are considered to be very helpful to the blood and circulatory system. Magnet therapy has come into vogue in the last twenty years and is becoming pretty commonplace nowadays. Even athletes and physicians are trying magnetic therapy, and any controversy about this onetime New Age healing method is fading thanks to the many positive endorsements.
