A granular mixed sulphide matrix of Pyrite, Quartz and probable chalcocite and sphalerite, is richly covered with glassy, pink Manganoan Smithsonite crystals to about 6 mm. From the Tsumeb mine, in the Otjikoto Region of Namibia, this specimen is a very good example of the manganese-rich variety of the zinc carbonate Smithsonite. The crystals form slightly curved rhombohedrons, are translucent and under a lens are bright candy-pink. When viewed at a normal distance, without magnification, the colour appears a dark pink due to the almost black underlying matrix. On the base of the specimen is a small cluster of acicular Quartz crystals to about 5mm, a surprisingly rare occurrence at Tsumeb. A terrific Manganoan Smithsonite from Tsumeb and a good size for display.

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.
