Mineralogical Identity & Physical Constants: Pyrite is an iron disulfide mineral with the chemical formula FeS₂, crystallizing in the isometric (cubic) system. Celebrated historically as “Fool’s Gold” due to its sun-like metallic sheen, gemological testing separates it definitively from native gold: Pyrite produces a diagnostic greenish-black to brownish-black streak on unglazed porcelain, has a dense specific gravity of 4.95 to 5.10, and rates 6.0 to 6.5 on the Mohs hardness scale. Unlike soft, malleable gold, pyrite is brittle and cannot be scratched with a mild steel pocketknife.

Cultural & Ornamental Context: Pyrite has a distinguished heritage in global lapidary dating back to antiquity. Ancient Mesoamerican cultures polished large pyrite slabs into reflective ritual mirrors, and in Victorian fine jewelry, faceted pyrite was popularized internationally as “Marcasite.” Customary modern jewelry styles mount polished pyrite in Sterling Silver (925 Silver), Copper, or Panchdhatu bezel settings for statement signet rings and pendants.
