This large chunk of Iron Pyrite, 2-3 inches in diameter, is great for any mineral collection.
The name is derived from the Greek ’fire’ as it produced sparks when struck. Beacause of its similarity to gold, pyrite is often called fool’s gold. Pyrite is a brass to golden colored iron, often found with well formed crystals and a metallic luster.
