More information
Typically sourced from
Peru (Huanzalá), Spain (Navajún), and Italy (Elba), this mineral often
forms perfectly-shaped millimeter-scale cubic or octahedral crystals.
It forms by hydrothermal or diagenetic precipitation in sedimentary
settings and metallic veins. Hardness 6–6.5 Mohs, density 5.0–5.2
g/cm³, golden metallic luster (“fool’s gold”).
Highly sought by micromineral collectors for the
perfect geometry of the crystals; used in jewelry as a decorative
stone; historically mined as a source of iron and sulfur .
