Wulfenite

Characterized by its square tabular crystals, orange to yellow color, high luster and association with other lead minerals, wulfenite is found in the oxidized zones of hydrothermal lead deposits. Discovered in 1845, it is named after the Austrian Jesuit mineralogist, Franz Xavier von Wulfen (1728-1805).
