Pyrite is often mistaken for "Fool's Gold" because of it's gold like color and opaque crystals.
ICSD collection code:
Pyrite comes from the greek phrase pyrites lithos, meaning "the stone which strikes the fire." Pyrite is very common worldwide, found mainly in Illinois, Missouri, South Africa, Peru, Germany, Spain and Russia; therefore, is easy to collect or buy. It's the most important source of sulfur other than native sulfur. Pyrite was once mined for its sulfur content and used in World War II as a strategic chemical. It is used today as jewelry and is one of the most collected minerals because of its gold like appearance.
