Strange elongated crystals of this rare varietal of willemite, yellow willemite, were found sporadically in small pockets in the deepest workings of the third oxidation zone at Tsumeb (I am told mostly in the mid to late 1970s). Many such examples were mistakenly identified as the more common adamite, or as the more rare species warikhanite. But this style, shown here, is really quite distinct. This is a superb, full thumbnail sized example of Tsumeb yellow willemite. It is a vivid yellow color, and sparkles like sugar! From an old German collection I recently got into, this is one of the best quality examples of the material I have seen for sale (in any size range)
