Formed via hydrothermal vein systems where metal-rich fluids precipitate minerals into fractured host rocks over millions of years.

Uses & applications

Used in mineral collecting, ornamental lapidary items, and educational displays.

Geological facts

Pyrite is commonly known as 'Fool's Gold' due to its deceptive metallic brassy yellow luster.
