4.2 x 3.6 x 2.1 CM (miniature)
Early summer 2021
Pink Smithsonite in rhombic crystals from Tsumeb. Sharp, gemmy and very lustrous, this is a small miniature (toenail) in fine condition. Tsumeb pink Smithsonites are distinctive, nothing like these are known from anyplace else, and the mine will never again produce these.
Dolomite - iridescent
3 x 2.4 x 2.3 CM (small miniature/ large thumbnail (toenail))
new year 2021
An unusual and attractive thumbnail of Dolomite crystals from Tsumeb with iridescent sheen. An older piece originally labelled "Cobaltoan Dolomite, Tsumeb SWA", however, this does not look at all like the usual Cobalt coloring and doubt the accuracy of that. This is however unusual looking for Tsumeb the crystals are sharp, slightly curved and have reddish-purple highlights.
Small miniature of well-formed, transparent elongated Smithsonite crystals from the great Tsumeb Mine. Remarkably this delicate specimen is perfect, no damage seen even under good magnification. In person these are very glassy and have a faint hint of yellow color, and at some angles the reddish matrix seen through the crystals gives a pink hue. I would call this close to colorless. Tsumeb was the source of so many colors, habits and associations for Smithsonite. This piece is really esthetic, it has a little Galena on the back side but the front is all nice Smithsonite.
2.6 x 2 x 1.2 CM (thumbnail)
A cluster of very sharp Tennantite crystals with no matrix. The patina on this thumbnail is a sooty dark metallic which is typical for Tsumeb. Displays well from several angles, the Tetrahedral form crystals form a sculptural grouping that shows the textbook perfect form well.
7.3 x 4.8 x 2.2 CM (cabinet)
A very fine deep emerald green Dioptase from Tsumeb with the intense color that can not be done justice on a computer. Wet-look luster and sharp transparent crystals densly cover the matrix plate. No damage and far better in person. Tsumeb Dioptase is known as a bit different from that found any place else. When at its best it is the most intense color in the world. This has that color. Ex. Charles M. Noll collection, from the heyday of the mine, mid seventies vintage.
Azurite - rosette nodule
4.6 x 4.4 x 3.9 CM (miniature)
From the brief attempt to reopen the great Tsumeb mine for specimen extraction this is a fine example of a rosette nodule. From the 5.1 sublevel of the west 4 stope this specimen shows unusually large crystal blades and classic radiating form that is much more distinct than were most that were found. In fine condition, complete and quite unlike most of the Azurite from Tsumeb.
A fine thumbnail of Anglesite showing the entire crystal form perched on a sliver of matrix, from Tsumeb.
This habit of Anglesite with the zoned dark inclusions is distinctive. In fine condition, no damage can be found even at 20X magnification. One end of the crystal has both Pyrite and Galena in small crystals and masses on the exterior faces, the other end is uncoated except for some micro Cerussites (white) not seen without good magnification. There are dark inclusions of what is most likely Galena seen at several places but mostly near the terminations as dark zones. The matrix here is mostly a druse of small Anglesites that are black, lustrous and thickly included with Sulfides. A choice Tsumeb piece and a nice Anglesite.
An extraordinary, esthetic Tsumeb Azurite with crystals in compound clusters much like flattened rosettes and curved prisms. Presents well from all sides and in perfect, undamaged condition. Similar in some ways to a few specimens we have seen with this habit from the famed Easter pocket, this piece is not attributed to that find but reportedly is from an older discovery. Far better in person, the blue is an intense deep hue that is almost impossible to render on a computer screen.
