Physical properties

Formation & geological history

Formed as a secondary mineral in the oxidized zones of lead-bearing deposits. Often results from the alteration of galena and other lead minerals in arid climates. Common in regions like Mibladen, Morocco.

Uses & applications

Primarily a collector's mineral due to its aesthetic crystal formations and vibrant colors. It is also an important ore of vanadium, which is used to strengthen steel alloys.

Geological facts

Vanadinite is a member of the apatite group of minerals. It is noted for its high lead content and distinctive hexagonal prismatic crystals that are often hollow or 'hoppered'.

Field identification & locations

Identified in the field by its high density (heavy feel), bright red/orange color, and hexagonal crystal habit. Common locations include Morocco, Arizona (USA), and Mexico. Collectors should avoid inhaling dust due to lead content.
