The mineral pyrite, or iron pyrite, is an iron sulfide with the formula FeS2. This mineral's metallic lustre and pale-to-normal, brass-yellow colour have earned it the nickname fool's gold because of its resemblance to gold. The term pyrite may also be used for some other sulphides such as copper sulphide. view more...
