Pyrite is also known as “Fool’s Gold”. It is commonly well crystallized and exhibits beautiful crystal forms. It is golden yellow like gold, only slightly paler, and is thus readily recognized. Its chemical composition is FeS2. Forming under all temperatures in every rock formations pyrite is the most widely distributed sulphide mineral.
