A truly classic Cobaltoan Smithsonite from 26 Level in the Tsumeb mine in Namibia. 26 Level was in the upper section of the Second oxidation zone and when mined in the early 1970s, this zone became famous for its spectacular pink Cobaltoan Smithsonites with modified crystal morphology. This delightful specimen is a druse of large, highly-modified rhombohedral crystals, some to over 2 cm across covering shallow vugs in a grey sulphide matrix, probably dominated by granular anhedral Chalcocite. The specimen is made particularly attractive by the subtle yet distinctive colour variations that range from pale flesh pink to deep bubble gum pink. Colour gradation gives the specimen a blushed appearance, making it a highly desirable example of Cobaltoan Smithsonite from Tsumeb.

Smithsonite from Tsumeb, Namibia
is one of the defining collector minerals of Tsumeb: not merely because it is common there, but because Tsumeb turns a usually massive or botryoidal zinc carbonate into a locality signature mineral with uncommon crystal variety, depth of color, and association. Tsumeb smithsonite spans the familiar apple-greens and blue-greens of copper-bearing material, soft pink to violet-pink cobaltoan and manganoan-looking rhombs, yellow-brown and chocolate-brown iron-rich crystals, pale grey to white crusts, colorless to translucent rhombs, and rare red-pink material from the deeper oxidized workings. The best specimens combine sharp rhombohedral or scalenohedral crystals with the sculptural mineralogical theater for which Tsumeb is famous: galena-rich sulfide matrix, sugary dolomite, black tennantite and pyrite ore, cerussite, mimetite, malachite, wulfenite, duftite, dioptase, and willemite.
