A large specimen from Bleiberg (Type locale) that is mostly Hydrozincite some formed over and with Smithsonite. Very well defined bothroids on a cast of Gossan that has additional layers of Hydrozincite seen on the underside. In fine condition, fluorescent and with some luster. One old label included mentions only the Smithsonite. For what is often an un attractive mineral specie, this is quite attractive and well composed.
