Physical properties
Hardness: 6-6.5 on Mohs scale; Color: Pale brass-yellow; Luster: Metallic; Crystal Structure: Isometric (cubic, octahedral, or pyritohedral); Cleavage: Indistinct; Specific Gravity: 4.8-5.0
Formation & geological history
Forms in a wide variety of geological settings, from sedimentary rocks like shales and coal beds to hydrothermal vein deposits and metamorphic rocks, typically precipitated from aqueous solutions.
Uses & applications
Historically used to strike fire, currently used in the manufacture of sulfur and sulfuric acid, and popular among mineral collectors and in jewelry.
Geological facts
Familiar as 'Fool's Gold' due to its superficial resemblance to gold, pyrite frequently forms striking natural cubic crystals.
Field identification & locations
Easily identified by its brass-yellow color, metallic luster, high specific gravity, and the fact that it cannot be scratched by a knife (unlike real gold). Found worldwide, with notable deposits in Spain, Peru, Italy, and the USA.
