Tsumeb is a locality that has a super premium in our world, for its incredible wealth of specimens. Among the great things it produced, once upon a time, were these beautiful translucent, botryoidal blue willemites. I am told that most came out in the 1970s, with some earlier. This label from Dr. Gary Hansen dates to prior to 1984 when he retired as a mineral dealer. He pulled this piece from his stock and kept it in his personal collection, until 2004. This particular specimen is intriguing because it is the only one of them I have seen with malachite association. The gemmy, botryoidal, willemite is unique and beautiful, and comes in this style only from Tsumeb.
