Wikipedia summary
Stolzite
Stolzite is a mineral, a lead tungstate; with the formula PbWO_4. It is similar to, and often associated with, wulfenite which is the same chemical formula except that the tungsten is replaced by molybdenum. Stolzite crystallizes in the tetragonal crystal system and is dimorphous with the monoclinic form raspite.
