Pyrite: Fool's Gold with a Heart of Metallic Brilliance
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.

Rainbow pyrite is a special type of pyrite known for its dazzling display of iridescent colors. This iridescence doesn't come from the pyrite itself but from a layer of minerals on its surface. The colors of rainbow pyrite can shine in hues of gold, green, pink, and blue, depending on how light interacts with the thin layers on its surface.
Pyrite: The mineral pyrite information and pictures
Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing localities.Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.
