Red Vanadinite on Matrix

Physical Properties

Hardness: 3.0-4.0; Color: Bright red, orange-red, brownish; Luster: Resinous to adamantine; Crystal Structure: Hexagonal; Cleavage: None; Specific Gravity: 6.6-7.2 (very heavy for its size).

Formation & Geological History

Formed as a secondary mineral in the oxidation zone of lead-bearing hydrothermal ore deposits. The red color is often due to the oxidation of vanadium within the lead-rich environment.

Uses & Applications

Primarily a collector's mineral. Industrially, it was once a minor source of vanadium, which is used to strengthen steel and in chemical catalysts.

Geological Facts

Vanadinite is known for its high density and striking hexagonal crystals. The Mibladen area of Morocco is world-famous for producing the highest quality specimens, characterized by deep red, tabular crystals.

Field Identification & Locations

Identify in the field by its high density (feels heavy for its size), hexagonal crystal shapes, and vibrant red/orange hue. Often associated with minerals like galena and barite. Found prominently in Morocco, Arizona, and Mexico.
