Likely pyrite (“fool’s gold”) fragment
Pyrite, FeS₂
AI-generated identification · may be incorrectThe tiny, reflective golden-brassy object is consistent with pyrite, but the image is too blurred for confident identification. Pyrite has Mohs hardness 6–6.5, metallic luster, and cubic crystals; color and shape here cannot be reliably assessed.

Physical properties
The tiny, reflective golden-brassy object is consistent with pyrite, but the image is too blurred for confident identification. Pyrite has Mohs hardness 6–6.5, metallic luster, and cubic crystals; color and shape here cannot be reliably assessed.
Formation & geological history
Pyrite forms in many settings, including hydrothermal veins and sedimentary rocks, through sulfur–iron reactions. Its age depends on its host deposit.
Uses & applications
Pyrite is collected as a mineral specimen and has been used as a source of sulfur and, historically, for ignition; it is not typically used as a gemstone.
Geological facts
Pyrite is iron disulfide and can resemble gold, but is harder and more brittle.
Field identification & locations
A clear close-up and tests for hardness, streak, and density would help distinguish pyrite from gold or another metallic mineral. Pyrite occurs worldwide.
