Pyrite, often called "Fool's Gold" for its metallic luster and pale brass-yellow hue, is an iron sulfide mineral with a Mohs hardness of 6 to 6.5. It commonly forms in cubic, octahedral, or pyritohedral crystals and can also appear in nodules or massive forms. Pyrite occurs in a wide range of geological environments and is found globally, with notable sources including Spain, Peru, the United States, and China. Its striking crystal habits and shiny surface make it a favorite among mineral collectors and educators.
