Pb₅(VO₄)₃Cl - Mohs Hardness: 2½ - 3. Vanadinite is an important ore of vanadium, and a minor ore of lead where it occurs with more abundant lead minerals. Its distinctive color makes it a very popular mineral among collectors. Vanadinite specimens from some localities may darken and lose transparency upon prolonged exposure to light, so this mineral should ideally be kept away from bright light.
