A sharp cluster of this very rare pseudomorph, which was found only in the oldest, upper oxidation zone of Tsumeb (prior to WWI, generally). The piece has a rich, deep green color to it and a nice 3-dimensional spread, to make it aesthetic. Recently, some have told me that the replacement is a mix of arsentsumebite and bayldonite, despite the traditional labeling as bayldonite replacements; but I have not had it analyzed yet. It is exceedingly difficult to find a good example of this old material and this 3-dimensional, colorful piece is a real cutie.
