An impressive display of translucent, cadmium (Cd) enriched Smithsonite crystals measuring to 1.3 cm aesthetically stacked upon one another, from the celebrated Tsumeb mine in the Oshikoto Region of Namibia. The modified rhombic Smithsonite crystals are ginger yellow to pale honey developed over colourless-white internal phantoms. The Smithsonite displays faint growth hillocks on the major faces and covers a characteristic matrix of Galena. Of all the various metal-rich varieties of Smithsonite to be found at Tsumeb, I am fairly certain the cadmium-rich variety is the rarest. This is supported by the presence of only nine mineral species at Tsumeb which contain cadmium. A small cabinet specimen of Cadmium enriched Smithsonite display three good sized crystals, each to over 1 cm.\n

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.
