Physical properties
Hardness of 6-7 on Mohs scale, golden-yellow metallic luster with white/grey quartz matrix, irregular to conchoidal fracture.
Formation & geological history
Formed via hydrothermal vein deposition where mineral-rich hot fluids cool and precipitate minerals into rock fractures.
Uses & applications
Commonly collected as a mineral specimen; historically used to strike fire and in low-grade ore extraction.
Geological facts
Pyrite is often called 'Fool's Gold' due to its metallic golden sheen, though it is harder and more brittle than actual gold.
Field identification & locations
Identify by its brassy yellow metallic flash and high hardness compared to native gold; found worldwide in metamorphic and sedimentary veins.
