Pyrite is a mineral that contains 53.5% sulfur and 46.5% iron. In most cases, Pyrite is solid, fine granular, or globular. Insoluble in water. Its name derives from fire, since rubbing it with other metals emits sparks. It is also known as "the gold of fools" or "the gold of the poor" for its great resemblance.
