Pyrite: FeS₂ T-Shirt

Pyrite doesn't need your validation. Dismissed for centuries as fool's gold, FeS₂ has been quietly doing the actual work — forming in hydrothermal veins, marine sediments, and metamorphic rock long before anyone showed up to misname it. The real thing, misread.

Center chest graphic pairs the chemical formula with the classic pyritohedron — the twelve-faced geometry that makes pyrite unmistakable to anyone paying attention. Available in three colorways. Wear the contrast level that feels right.

Garment-dyed 100% ring-spun cotton, relaxed fit, topstitched collar, twill-taped neck and shoulders. Gets better with every wash. $1 from every order goes to protecting public land.
