Thousands of mustard yellow, bowtie-like sprays of Tsumcorite. Tsumeb is the standard for this species. I don't think there is a comparable locality which represents the species like Tsumeb. This specimen is without doubt one of the better specimens that you will see available now or ever. The crystals are exactly the same as those shown in Gebhard's Tsumeb book on page 249 of the english version. It is from Gebhard's collection accompanied with his label also stating it is from the 2nd oxidation zone. The bottom side contains nice green Adamite.
