One of the rarest finds of Tsumeb, the gem blue willemite, is seldom seen for sale. This piece features thick gem quality botryoidal growth, of the purest color and deepest color you could ask for from the pocket. I am told this was found in the 1960s or early 1970s, and today I buy every one that I can get. This is a superb, balanced miniature. It was formerly in the American Museum of Natural History in NYC.
