An unusual and attractive combination piece consisting of Willemite, Smithsonite, and Cerussite. The main portion of the specimen is botryoidal Willemite, having a lovely, light, greenish-blue color and rich silky luster. It is translucent. Covering much of the Willemite appears to be a sugary coating of microcrystalline Smithsonite, Cuprian in nature but a deeper green than usual. And finally, decorating the top are numerous mm-size Cerussite crystals. A good combination piece from the greatest of mines, Tsumeb.
