Tsumebite is a rather rare Lead Copper Phosphate Sulfate and is only found from a few world localities. It was obviously named after the Tsumeb mine in Namibia. This piece is a good reference specimen of featuring green micro crystal aggregates of Tsumebite on matrix. If nothing else it is a unique collector's specimen from this secondary ore mineral locality in California.
