Kelly Mine, Magdalena
5.6 x 5.3 x 3.3 CM (cabinet)
Kelly Mine Smithsonite with the most desirable wet look luster and good blue color. Ex Hitchings collection this is in fine condition a few of the outer edges show where this was removed but all the display surface is perfect clean and undamaged. A few areas of the white mottling are present which adds a nice contrast. This is a pre 1970 specimen. These have become American classics and there is no other Smithsonite worldwide that has just this look, color and luster.
Xiafu, Zhoaping Co. Henzoh Prefecture
Guangxi Zhuang Autonomous Region,
7.8 x 6.4 x 4.3 CM (cabinet)
A colorful and very well formed knob of botryoidal Smithsonite with good yellow color. Choice and three dimensional, this looks great from most any angle. Except at the base where this was removed, there is no damage or bruises on any surface. The satiny luster is especially rich. These have been marketed as "Cadmium" Smithsonite but there have been some different analysis that conflicts with this and some claim that none of the yellow Smithsonites from any deposit owe their color to Cadmium. I suspect the truth is someplace in the middle. I do not know if Cadmium is involved in this specimen or this find but this is the sought after "Cadmium'" color. Excellent eye appeal and overall esthetics, no matter the color source. An excellent value for one of these complete knobs which are quite uncommon and priced far higher when available.
A fine Tsumeb Smithsonite that is a very rare blue to deep blue green color. The Smithsonite also has some small Calcite crystals on some surfaces that are colored reddish from Hematite. The outer edges show some very minor chipping but the entire display surface is in pristine condition, very lustrous and undamaged. I have only seen a very few specimens of this color an they were thumbnail sized. The specimen is double sided but the back is a red-brown color botryoidal smithsonite that is far less attractive than the front side. A very nice esthetic specimen with great color but an especially great addition for a Smithsonite suite or Tsumeb collection
Smithsonite with Mimetite
5.2 x 3.2 x 3 CM (small cabinet/ large miniature)
Cuprian Smithsonite from Tusmeb fills an open seam on the matrix and has partly covered several golden Mimetite crystals. In fine condition, ex. Loben collection (with label) collected in 1986, close to the end of the Tsumeb era. The Mimetites are the slender pointed type and the overgrowth of the Smithsonite crystals is like a cloak. Great luster and excellent condition, the paragenesis is especially clear on this specimen.

Late Summer 2018
Brilliant Cadmium yellow color Smithsonite from this very small, ancient mine. Worked only from 1862-1863, this held a colorful vein of Smithsonite that was waste rock at the time but today are prized as one of the few true Cadmium Smithsonites. Ex Lindsay Greenback (an old secured minerals label is included) specimen, this has good luster and the rich color that is the most desirable. A few bruises mostly on the edges but in reasonable condition overall as seen. There are fluorescent zones as well, these are not very often available and this has color better than most.
A choice Greek Smithsonite with deep color, bright luster and excellent form. In undamaged condition as seen, the fingers and globs of Smithsonite rise from a contrasting gossan matrix. This is from one of the oldest mineral localities on the planet, and is an attractive example of the orange-brown color. Nice sparkle in person.
A choice small cabinet Smithsonite made of purple and pink botryoidal layers over a green core. There is minimal matrix. From the now defunct Choix locale, this has a fine color and luster that is much better in person. In undamaged condition, these Smithsonites are no longer being found. A modern classic locale, better specimens like this really do stand out and are a good value.
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.
