Physical properties

Formation & geological history

A secondary mineral formed in the oxidized zones of lead-bearing deposits. It forms when vanadium-bearing fluids react with primary lead minerals like galena. Often found in arid climates.

Uses & applications

A major industrial source of vanadium metal, which is used to strengthen steel and in chemical catalysts. High-quality specimens are highly prized by mineral collectors.

Geological facts

Vanadinite is known for its exceptionally high density due to its lead content. While beautiful, it should be handled with care as it contains lead. The most famous locality for these large deep-red crystals is Mibladen, Morocco.

Field identification & locations

Identify by its deep red color, distinct hexagonal crystal shapes, and surprising weight for its size. It is commonly found in Morocco, Namibia, and the Southwestern USA. Keep away from direct sunlight for extended periods to prevent darkening.
