SOLD Smithsonite -rare color
stock #SOLD 18.1-694
Tsumeb
Otjikoto Region, Namibia
6.2 x 3.8 x 1.7 CM (cabinet)
price: $0
Dec 2018

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
Azurite with Arsentsumebite, Malachite etc.
stock #18.1- 636
Tsumeb
Otjikoto Region, Namibia
6.1 x 4.8 x 3.6 CM (cabinet)
price: $4400
Dec 2018

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.
Dolomite- cast with two generations
stock #16.1-305
Tsumeb
Otjikoto Region, Namibia
6.5 x 3.8 x 2.8 CM (cabinet)
price: $190
Dec 2018

A delicate and fine Dolomite cast having two separate generations. The large scalenohedral shapes are hollow having just a thin skin of Dolomite that had covered what were likely Calcites, now long gone. The matrix is an earlier generation itself just a thin skin of tiny sparkling crystals. The Dolomite casts from Tsumeb were found in many exotic forms are are very collectable. This one is in perfect condition, esthetic and looks fine from all sides.
Smithsonite with Mimetite
stock #16.1-672
Tsumeb
Otjikoto Region, Namibia
5.2 x 3.2 x 3 CM (small cabinet/ large miniature)
price: $360
Dec 2018

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.
Azurite
stock #15.1-598
Tsumeb
Otjikoto Region, Namibia
3.1 x 2.7 x 2.4 CM (small miniature/ large thumbnail (toenail))
price: $450
Dec 2018

A choice early Azurite from Tsumeb formerly in the Johannson collection obtained in trade with Harvard before 1933. Thick rectangular blades in a mass on minimal matrix. Excellent luster and a somewhat unusual form, this has some chipping and some rehealed areas that can hidden by angle of display. The edge modifications and faces on this Azurite are very unusual for Tsumeb and in fact for any locality.
Beudantite
stock #18.1-289
Tsumeb
Otjikoto Region, Namibia
3.1 x 2.9 x 1.3 CM (small miniature/ large thumbnail (toenail))
price: $180
Worldwide mix summer

Densely crystallized Beudantite covers the surface of this matrix. The crystals are very sharp, lustrous and translucent to transparent. In fine condition, a choice large thumbnail from Tsumeb the matrix has a tiny dusting of Arsentsumebite as well.
Calcite with inclusions of Malachite, Chalcotrichite and unknown.
stock #18.1-245
Tsumeb
Otjikoto Region, Namibia
1.7 x 1.8 x 1.6 CM (thumbnail)
price: $690
Worldwide mix summer

An incredible, crazy little Tsumeb thumbnail! A ball-like cluster of Calcite rhombs most of which are colored a cadmium yellow. In some other zones the color is deep red from included needle crystals of Chalcotrichite and a few are green from included Malachite. Malachite balls in chains along some areas add a nice green accent making a bright, very colorful specimen. In perfect condition damage wise, this is crystalized all around, a floater. It is not clear what is causing the Cadmium yellow color, it is not typical at all. Ex Hitchings collection dating to mid 1960 vintage. Unique.
Dioptase w. Calcite, Duftite etc.
stock #13.1-257
Tsumeb
Otjikoto Region, Namibia
4.3 x 3.8 x 2.7 CM (miniature)
price: $330
Spring update

Super colorful multi-specie specimen from Tsumeb. In fine condition with excellent luster and sparkle throughout. The Calcite rhombs are dusted with micro crystals of Dioptase which gives a sugar cube texture but with emerald green color. Very good display impact in person.
