description Pyrite Overview
Pyrite is a common iron sulfide mineral with the chemical formula FeS2. It usually crystallizes in the cubic system and is recognized by its metallic luster and pale brass-yellow color, which give rise to the name fool's gold. Pyrite is harder and more brittle than gold and can occur in igneous, metamorphic, and sedimentary rocks. It has been mined as a source of sulfur and has also been cut or polished for specimens, ornaments, and limited jewelry use.
