Vauquelinite - Sold

Vauquelinite is a lead copper phosphate chromate. Berzelius (1818) named the mineral after Louis Nicolas Vauquelin (1763-1829), chemist at the University of Paris, who discovered chromium.

Vauquelinite here forms lustrous nearly black micro-crystals to 0.5 mm. Also present are flattened, contacted crystals of crocoite, indicating that these crystals formed in a rarrow fracture. This specimen comes from the type locality for both vauquelinite and crocoite, and also for the element chromium. This specimen comes from the collection of Allen Parker. The specimen carries labels from Carlton Davis and from dealers Mineralogical Research and Schortmann's Minerals.
