Physical properties
Hardness 3 on Mohs scale, reddish-brown to bright red color, resinous to adamantine luster, hexagonal crystal system, specific gravity around 6.8-7.1.
Formation & geological history
Formed as a secondary mineral in the oxidation zone of lead-bearing ore deposits, typically through the alteration of primary galena.
Uses & applications
Primary ore of the metal vanadium and highly sought after by mineral collectors for its striking crystal clusters.
Geological facts
Vanadinite belongs to the apatite group and its high specific gravity makes it feel surprisingly heavy for its size.
Field identification & locations
Identified easily by its distinctive barrel-shaped hexagonal prisms and vibrant red-brown color; found notably in Morocco, Arizona, and Mexico.
