The classic habit of saddle shape Dolomite crystals completely replaced by sparkling smithsonite. The matrix is also nearly all Smithsonite and mostly composed of the rare red-orange color but also has zones of the more typical yellow. A long running debate concerns the color being caused by either Cadmium or Greenockite inclusions. To me it is a distinction without a difference, Greenockite is simply Cadmium Sulfide and so that Cadmium is ultimately the source for the color. In good condition, only a few very minor abrasions can be seen, the Dolomite saddles are quite large and stand well above the matrix.

Bright pink Smithsonite in a bubbly habit with no adhering matrix. Fine color and luster in an attractive shell-like cast structure. From the long known prospects at Choix, Simaloa, Mexico. Sadly this locality has had many problems and has stopped producing due to cartel violence. The bright colored Smithsonites from here are now highly regarded as fine specimens.

The rare intense color most desired for a fine Cobaltoan Smithsonite. Well crystallized and in perfect condition this is a classic Tsumeb specimen with first rate esthetics. Rich purple-pink hue and 360 degree display ability give this thumbnail top marks. Choice and better in person.
Bright purplish-pink color dominates this small cabinet specimen with several spherical groups of Smithsonite crystals on a Sulphide matrix. In contrast there are several Cerussites some twinned and in fine condition as well. Most Tsumeb Cobaltoan Smithsonite is a rather pale pink color this is really deep strong color, electric and impressive.
Pink gemmy crystals of Cobaltoan Smithsonite in on a perfect condition thumbnail. From the great Tsumeb mine, this looks better in person, has the rich, lustrous color that is the most desiarable. The better Tsumeb pink Smithsonites are the worlds best, this small specimen show why.
This specimen is one of a kind, a unique Tsumeb oddity with great esthetics. An elongated, gemmy crystal of Smithsonite rises from a gossan matrix and hosts a few gem clear smokey Cerussites. The Smithsonite shows signs of being a compound crystal with parallel growth but a single termination. The Cerussites and a tiny part of the Smithsonite (only seen with magnification) are chipped but this is on the "back" not visible on display, the front and side view are pristine undamaged. Tiny Calcites with some odd habits are also scattered on the matrix. The crazy composition of this specimen is typical of why so many collectors love Tsumeb minerals.
A fine and very unusual type of of Smithsonite specimen from Tsumeb. Ex John Schneider collection, this has light pink to violet transparent crystals of Smithsonite densely covering 3 parallel fingers or stalactites of Galena. In excellent condition with wonderful esthetics, this is a really weird but choice Tsumeb specimen.
From the noted collection of Wallace Gould Levison, purchased by him in 1893 from an even older collection obtained by HG Diserow, seemingly pre 1870. Classic translucent Smithsonite from Laurium with fine blue green color, sawn and lightly polished. A photocopy of Levisons handwritten catalog entry page for this specimen is supplied with the piece. Levison was an important Victorian era US collector, inventor (first patent for a movie camera, UV mineral systems etc.) and prolific author.
