Pyrite's classic brassy yellow color can range from a pale, almost silver tone to a deeper gold. This yellow tone distinguishes it from other metallic minerals like gold, magnetite, hematite, and chalcopyrite. With a Mohs hardness of 6 to 6.5, pyrite is a durable mineral resistant to abrasion. However, its brittle nature makes it prone to breakage under pressure.
