Vanadinite is an uncommon, but beautiful, reddish-colored lead chlorovanadate (Pb5(VO4)3Cl). Vanadinite has hexagonal crystals, a hardness of 3, and a nonmetallic luster described as adamantine or resinous.
The highest quality vanadinite is from Morocco in northwestern Africa. The sample shown below is a nice vanadinite cluster on Lower Jurassic dolostone. It comes from the A'hcif Mine (A'hcif Shaft), near the old mining village of Mibladen, ~15 km northeast of Midelt, eastern Khenifra Province, northern Morocco.
