Smithsonite comes in many varied forms at Tsumeb mine, with the pink Cobaltoan variety being one of the most eye-catching and desirable. This miniature specimen displays a rich coverage of sharply formed rhombic Cobaltoan Smithsonite crystals with a candy floss (or cotton candy) to salmon pink colour, almost reminiscent of some paler coloured Rhodochrosite. Indeed, like Rhodochrosite, the colour varies depending on the source of light. This is seen here between the photo and the video. The crystals are mostly around 5 mm in size and present a fine translucent to transparent appearance allowing the internal cleavage planes to be seen. The Cobaltoan Smithsonite sits upon a mixed sulphide matrix and is in great overall condition. A very pretty Tsumeb Smithsonite to brighten up your day.

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.
