Physical properties

Small, rough, brassy-gold specimen with metallic luster; likely Mohs hardness 6–6.5 and cubic crystal structure. The photo is not detailed enough to confirm its identity or cleavage.

Formation & geological history

Pyrite forms in many geological settings, including hydrothermal veins and sedimentary rocks; specimens can range from geologically recent to billions of years old.

Uses & applications

Used historically as an iron and sulfur source; today it is mainly collected, with limited industrial use.

Geological facts

Often called “fool’s gold,” pyrite is harder and more brittle than native gold and may show cubic crystals.

Field identification & locations

Look for a brassy color, metallic shine, and brittle fracture rather than gold’s softness and malleability. Found worldwide, including in sedimentary deposits and mineral veins.
