Rich deep rose pink crystals of Cobaltoan Smithsonite form a gently rounded dome resting on a naturally flat base. The specimen is from the Tsumeb mine in Namibia, where Smithsonite was the most abundant secondary zinc mineral. Coloured pink by traces of cobalt, the crystals although vivid pink do contain a reddish tinge, making this specimen standout all the more. The crystals are completely intergrown forming as characteristic curved rhombs and measuring up to 1.4 cm on edge. Their faces are smooth yet display growth ripples generally placed diagonal to the prism face with a most attractive silky lustre. This is a beautiful miniature 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.
