Galena

Galena was named by Pliny the Elder (77-79) after the Greek name for the lead ore "galene". It is most often lumpy or grainy. Its crystals tend to be abundant, either as cubes or octagons or couplings of cubes and octahedron. After breaking, it disintegrates into small cubes. The color is steel gray and metallic luster. Occurs on hydrothermal ore veins, it is one of the most abundant sulfides in most ore deposits. It is the most important red lead, but also a source of silver, which is usually its admixture.
