Physical properties
Hardness 6-6.5 on the Mohs scale, brassy yellow metallic color, metallic luster, cubic crystal system, and a greenish-black streak.
Formation & geological history
Formed in sedimentary, igneous, and metamorphic environments through hydrothermal activity or low-temperature precipitation.
Uses & applications
Commonly collected as mineral specimens, historically used to strike fire, and utilized in the manufacture of sulfur and sulfuric acid.
Geological facts
Known colloquially as 'Fool's Gold' due to its superficial resemblance to real gold, pyrite often forms near-perfect natural cubic crystals.
Field identification & locations
Identified easily by its brassy color, high density, and cubic habit; found worldwide in association with coal deposits and hydrothermal veins.
