Andradite var Demantoid
Tubussis Farm 22, Daures
6.2 x 5.4 x 4.2 CM (cabinet)
A fine cluster of stacked Demantoid Garnets that contrasts well with the matrix. Excellent color and luster, the main Garnets are 2.6 CM tall and in fine condition. No damage seen even under high magnification. The matrix is a mix of Quartz, Calcite and Prehnite, this holds several smaller Andradites as well. These were big mineral news a few years ago when they were more available, these are now quite scarce.
Copper in Calcite
Onganja Mine, Windhoek District
4.9 x 3.8 x 3.5 CM (miniature)
An exceptional (and very unusual) Copper in Calcite from the great Onganja Mine. A large sharp transparent Calcite 3.8 CM across sits on and is included by Copper. The matrix is partly Copper, Malachite and Chalcotrichite. The Calcite is unlike most from Onganja as it is a simple modified rhomb without the complex habits or twinning that is typical from here. This displays well from most any angle, in very good condition with only very minor rub spots. The Onganja mine was once a prolific source of fine Coppers, Cuprites etc but the Calcites were always especially rare and sought after. The mine has been closed and flooded for years. This specimen is quite striking in person and a significant Copper.
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
Beryl var Goshenite- elongated crystals
Hohenstein Massif, Omaruru District
3.6 x 3.1 x 2.9 CM (small miniature/ large thumbnail (toenail))
A superb toenail sized Erongo Goshenite. Perfect colorless Beryl crystals sprout from a Feldspar matrix in an attractive array. Excellent luster, clarity and with a slender habit all the crystals are terminated with the flat top and some tiny pinnacoid faces. An older specimen of a type almost never available. No damage at all, the specimen could be trimmed to a fine competition thumbnail but also looks great as is.
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.
A bizzare, unique, rare but attractive Aquamarine. From the Erongo Mountains, (Hohenstien Massif) this is a complete, doubly terminated crystal. The flat termination is typical although in this case the corners have modified faces. The real interest is the other termination that is a series of hexagonal steps that are perfectly centered like a stairway or a turret. The 4 main steps or platforms are very flat and some edges have a little etching, the whole is therefore a reversed scepter. Some minor contacting/chipping is noted but overall the condition is excellent. A good display piece but especially a great addition for a suite of Namibian/ Erongo minerals, Beryls or exotic crystal forms.
3.4 x 2.4 x 1.5 CM (small miniature/ large thumbnail (toenail))
A super clean, brilliant toenail sized Dioptase from finds at Kaokoveld in 2012. Very sharp and lustrous crystals in excellent condition and having an esthetic arrangement. While Dioptase is known from quite a few localities in the world but this sort of very fine specimen is from either Tsumeb (closed forever) or Kaokoveld, bot being in Namibia. Top emerald green color with transparent areas set this apart, better in person.
Berg Aukus, Grootfontein District
5.3 x 2.4 x 1.4 CM (small cabinet/ large miniature)
A lustrous, flattened crystal tree or leaf-like structure of oriented Descloizite crystals in super condition. A textbook example of epitaxial arrangement or stacking. The individual crystals are a dark red color in strong light but in normal light they look black to metallic silvery. The crystals are undamaged, some are also transparent. Great form and sparkling luster, these fine Berg Aukus specimens have become rare in this quality. The Descloizites from this closed mine are regarded as the best ever found and are modern classics.
