It can be most often found as thin tabular crystals with a bright orange-red to yellow-orange color, sometimes brown, although the color can be highly variable. In its yellow form it is sometimes called "yellow lead ore".

Wulfenite is named for Franz Xavier von Wulfen (1728-1805), an Austrian mineralogist.

Wulfenite is found in many localities, associated with lead ores. It is highly prized by collectors of mineral specimens. This article is about the chemical element. ...

In the Southwest, collectors can be provided with the largest diversity of specimens of wulfenite, ranging across a full spectrum of colors. Mining software pioneer and well-known Southwest collector, Richard A. Bideaux, is known for his extensive collection of wulfenite, along with a slew of many other secondary lead minerals (vanadinite, mimetite, crocoite). His specimens are valued in museums across the world as providing an extensive example of the most exquisite wulfenites in the world.
