Physical properties
Hardness: 6-6.5 on the Mohs scale; Color: Pale brass-yellow; Luster: Metallic; Crystal Structure: Isometric; Cleavage: Indistinct; Specific Gravity: 4.8-5.0
Formation & geological history
Formed in hydrothermal veins, sedimentary rocks, and metamorphic environments through the precipitation of iron and sulfur.
Uses & applications
Used in the production of sulfur and sulfuric acid, educational specimens, and occasionally in jewelry or decorative items.
Geological facts
Often nicknamed 'Fool's Gold' due to its superficial resemblance to real gold, though it is harder and more brittle.
Field identification & locations
Easily identified by its bright metallic brass-yellow color, high density, and cubic or pyritohedral crystal habit. Commonly found worldwide in association with other sulfide minerals.
