Possibly pyrite (fool’s gold)
Pyrite, FeS₂
AI-generated identification · may be incorrectThe small rounded specimen appears brassy and metallic, but the image is too blurred to confirm. Pyrite has Mohs hardness 6–6.5, an isometric crystal structure, and no distinct cleavage; a naturally rounded shape may result from weathering or tumbling.

Physical properties
The small rounded specimen appears brassy and metallic, but the image is too blurred to confirm. Pyrite has Mohs hardness 6–6.5, an isometric crystal structure, and no distinct cleavage; a naturally rounded shape may result from weathering or tumbling.
Formation & geological history
Pyrite forms in many settings, including hydrothermal veins and sedimentary rocks; it occurs from ancient rocks to modern deposits.
Uses & applications
Used as a source of sulfur and historically for iron; attractive pieces are collected, though it is not a durable jewelry stone.
Geological facts
Its metallic color can resemble gold, but pyrite is harder and typically breaks rather than flattening when struck.
Field identification & locations
Check for a brassy streak, cubic crystals, and brittleness; these clues help distinguish it from gold. Pyrite occurs worldwide, but the image does not show enough detail for reliable identification.
