Pyrite, commonly known as "fool's gold," is a metallic mineral that has been historically mistaken for gold due to its striking golden luster and color. Its name is derived from the Greek word "pyr," meaning "fire," as pyrite sparks when struck against metal or stone. Despite its nickname, pyrite is an iron sulfide (FeS₂) and has a cubic crystal structure, making it easily distinguishable from real gold. Beyond its aesthetic appeal, pyrite plays an important role in geology, mining, and even as a potential energy source.
