Extremely elongated delicate tapering Smithsonite crystals are an unusual, and very rare, feature of the extensive oxidation deposits at Tsumeb mine in Namibia. This miniature specimen is a rare example of this Smithsonite crystal habit where the frosted white elongated crystals rise out from a Goethite-coated Dolomite-Calcite matrix. The individual crystals are extremely large for this form from Tsumeb, reaching 1.7 cm in length, and one of them displays epitaxial overgrowth of more Smithsonite. The way these crystals splay out from the matrix is quite spectacular. Under magnification the Goethite presents a lovely velvety appearance. Ex Weyand collection.

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.
