Physical properties

Hardness: 3.0-4.0; Color: Bright red, orange, brown, or yellow; Luster: Adamantine to resinous; Crystal structure: Hexagonal; Cleavage: None; Specific gravity: 6.6-7.1

Formation & geological history

Formed in the oxidation zone of lead-bearing deposits through the weathering of primary minerals like galena. Vanadium is often leachedจาก host rocks like shale.

Uses & applications

Primary source of industrial vanadium; used in steel alloys and chemical catalysts. High-quality specimens are highly prized by mineral collectors.

Geological facts

Vanadinite is known for its distinct hexagonal prism crystals. It was first discovered in Mexico in 1801 by Manuel del Rio, though it was later formally characterized in 1838.

Field identification & locations

Identify by its hexagonal barrel or prism shape, high density (very heavy for its size), and bright color. Common locations include Morocco (Mibladen), Namibia, and Arizona.
