Tetrahedrite is a relatively rare lead copper sulfide mineral with the chemical formula Cu12Sb4S13. It has a tetragonal crystalline structure, and its name refers to the tetrahedral shape of the copper and antimony ions within the crystal structure. Tetrahedrite is found in hydrothermal veins and igneous rocks, often in association with other copper or lead minerals. It has a dark brown to silver-gray color and a metallic luster. Tetrahedrite is relatively soft, with a Mohs hardness of around 3-4. It has been used as an ore of copper and in various industrial applications, including the production of television tubes and nautical chronometers.
