Galena

color photo of galena sample

Hardness: 2.5

Galena is lead sulfide (PbS), the principal mineral of lead ore. It occurs as metallic to lead-gray, cube-shaped crystals that break into cubic, right-angled fragments. Some galena crystals are very large. Galena is heavy, has a metallic luster on fresh surfaces, has a gray-black streak, and is so soft that it will mark on paper. Galena was once mined in the Tri-State mining district, formerly one of the most important lead- and zinc-producing areas in the world.
