Pyrite was once called fool's gold by miners, because so many mistook it for gold. Pyrite is actually iron sulfide and has an opaque, shiny, metallic luster.
Pyrite is named for the Greek word pyr, meaning fire, because this stone produces sparks when struck with steel.
Pyrite stone has been used in jewelry and ornamentation for thousands of years. North American Indians used pyrite as amulets, which medicine men employed in the course of their incantations.
Metaphysically, pyrite is believed to foster intelligence, logic and analytical ability. All that and it also happens to be magnetic.
