Manganoan Smithsonite

Unknown Owner
This is a manganoan smithsonite rather than the stereotypical cobaltoan smithsonite. These manganoan smithsonites were mined 1984-1985 and are much harder to find than the cobaltoan variety. This particular specimen has the stereotypical matrix of pyrite and other sulfides that these manganoans often feature.

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.
