Iron Pyrite (Peru)

A piece of iron pyrite from Peru. Iron pyrite is a sulfide mineral known for its brassy, metallic luster. It forms in cubic crystals or nodular masses, typically in sedimentary rocks or hydrothermal veins, where sulfur and iron combine under specific conditions.

Despite its lack of precious metal value, pyrite’s striking appearance and historical role in early spark-making (striking it produces sparks) make it a fascinating piece of Earth’s mineral story.

This is genuine geological sample. All the specimens we offer come with a lifetime authenticity guarantee.
