In the mid-1960s I was employed as a mineralogist in Tsumeb. This specimen with very good crystals of zinc spar dates from this period and is largely covered by a wafer-thin layer of vanadinite. A small cerussite triplet sits on the side, on the underside are numerous very small green zinc spar crystals
