Physical properties
Hardness of 6-6.5 on the Mohs scale, brassy-yellow metallic color, opaque with a brilliant metallic luster, and crystallizes in the isometric system with cubic or pyritohedral habits.
Formation & geological history
Forms in a wide variety of geological environments ranging from igneous and metamorphic rocks to sedimentary deposits, often precipitating from hydrothermal solutions.
Uses & applications
Historically used to strike fire and in early firearms, currently used in the production of sulfur dioxide and sulfuric acid, and widely collected as a mineral specimen.
Geological facts
Known famously as 'Fool's Gold' due to its superficial resemblance to real gold, pyrite frequently forms striking, perfectly geometric cubic crystals naturally.
Field identification & locations
Easily identified by its brassy-yellow color, high specific gravity, dark greenish-black streak, and cubic crystal habit; found globally in coal beds, limestone, and metallic ore veins.
