Physical properties
Hardness 3 on Mohs scale, bright red-orange to brownish-red color, resinous to adamantine luster, hexagonal crystal system, and a specific gravity of 6.8 to 7.1.
Formation & geological history
Forms as a secondary mineral in the oxidation zones of lead-bearing ore deposits, primarily in arid climates.
Uses & applications
Valued primarily as a collector's mineral specimen and as a minor ore of vanadium metal.
Geological facts
Vanadinite is known for its striking, brightly colored hexagonal crystal prisms that often form on a matrix of barite or limonite. It was originally discovered in Zimapán, Mexico, in 1801 by Andrés Manuel del Río.
Field identification & locations
Easily identified by its distinct hexagonal barrel-shaped crystals, high density, and characteristic bright orange-red hue. Commonly found in Morocco, Arizona (USA), and Mexico.
