What are the pyrite characteristics?

Pyrite, often referred to as "fool's gold," is a metallic mineral composed of iron sulfide (FeS₂). It has a distinctive brass-yellow color and a shiny metallic luster, which can easily be mistaken for gold. Pyrite typically forms in cubic crystals and can exhibit a hardness of 6 to 6.5 on the Mohs scale. Additionally, it is non-ductile and can produce a greenish-black streak when scratched against a hard surface.
