Pyrite The mineral pyrite information and pictures

Pyrite is sometimes called Fools Gold because of its similarity in color and shape to Gold the old mining days Pyrite was sometimes mistaken for Gold as they frequently occur together although Gold and Pyrite can very easily be distinguished by simple observation and testing of characteristics.
