Physical properties

Formation & geological history

A secondary lead mineral formed in the oxidized zones of lead-ore deposits, commonly in arid regions. It develops as lead-bearing minerals weather and react with vanadium-rich fluids; deposits are generally geologically young relative to their host rocks.

Uses & applications

Collected for its bright crystals and used as a mineral specimen; it is not a practical source of vanadium or lead today. Lead content makes it unsuitable for jewelry worn against skin or for handling by children.

Geological facts

Vanadinite is a member of the apatite mineral group and contains toxic lead. The pictured specimen is a digital model displayed on a phone, not a photograph of a physical specimen.

Field identification & locations

Look for vivid red-orange, heavy, brittle hexagonal crystals, often coating limonite or other oxidized lead ores. Notable localities include Mibladen, Morocco, and parts of Arizona, USA.
