For native elements, Tsumeb has always been a bit disappointing in terms of specimen recovery: especially for silver, of which so few fine specimens are known and of those, most are simply not display-worthy. This brilliant piece, however, is quite an exception! It features exquisite OCTAHEDRAL silver crystals to 3 mm set in massive silver, with spots of cuprian adamite to prove the locality is legit! In person, it is a much richer, silvery tone than it appears. Specimens of this richness are EXTREMELY RARE and hard to come by. The famous Barlow collection Tsumeb silver illustrated in his book, which I handled at one time, had perhaps 1/10th the silver as does this specimen though of course much more size and heft in the rocky matrix. I would choose this one every time, for its attractive, brilliant display qualities. From the Nauke Oechslin Collection, purchased in Africa in the early 2000: a noted collection mentioned in Gebhard's Tsumeb books. 4 x 3.5 x 1.25 cm
