    What is Pyrite? Pyrite is a brass yellow mineral with a bright metallic luster. It has a chemical composition of iron sulfide (FeS 2) and is the most common sulfide mineral.It forms at high and low temperatures and occurs, usually in small quantities, in igneous, metamorphic, and sedimentary rocks worldwide. Pyrite is so common that many geologists would consider it to be a ubiquitous mineral.
