  • Pyrite Mineral Uses and Properties

    Identifying Pyrite. Hand specimens of pyrite are usually easy to identify. The mineral always has a brass-yellow color, a metallic luster and a high specific gravity. It is harder than other yellow metallic minerals, and its streak is black, usually with a tinge of green. It often occurs in well-formed crystals in the shape of cubes, octahedrons, or pyritohedrons, which often have striated faces.

  • Pyrite Wikipedia

    Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold.The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.. The name pyrite is derived from the Greek πυρίτης λίθος (pyritēs lithos), "stone or mineral which strikes fire", in turn from

  • Pyrite Uses and Meaning Crystal Vaults

    Pyrite is most noted for its nickname, “Fool’s Gold,” the glittering rock notoriously mistaken by naïve prospectors as real gold. It was also used by dishonest mine owners to salt their mines for the purpose of convincing people they were still gold-producers. Although similar in hue, Pyrite is lighter in color than Gold, and is harder and more brittle. It can’t be scratched with a
