Dioptase very large crystal
3.1 x 1.3 x 1.2 CM (small miniature/ large thumbnail (toenail))
A fine large single prism composed of two main parallel crystals that are joining in a single shared termination. Super lustrous with brilliant color, in fine overall condition. The base has a few tiny adhering crystals that are not complete and it is possible to see the break where this was removed from the host mass of Dioptase where this grew. Aside from the matrix the main large crystal is in perfect undamaged condition. From finds a few years ago in the Kaokoveld, large prisms like this were just not known from other locations. A choice example of this find
Elbaite -gem Tourmaline
Usakos, Karibib District
2.7 x .9 x .9 CM (thumbnail)
A single, doubly terminated and gemmy clear Elbaite crystal from the Karibib. Namibian gem Tourmaline of any quality has become quite uncommon, it was last being found almost 20 years ago. Complete and in nice condition this one shows the striated faces and flat terminations that is typical of these Karibib crystals. Nearly all facet grade, the interior is transparent and clear deep green.
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.
Boltwoodite on Calcite
Goanikontes Claim, Goanikontes, Arandis
10 x 8.4 x 5.2 CM (cabinet)
An especially choice large specimen of Boltwoodite on a contrasting dark brown druse of Calcite. Protected by this shallow pocket, the radiating clusters of sharp bright yellow to orange needles are in excellent condition as seen. The radiating areas are about 1 CM across which is larger than typical as well. Special arrangements are needed in shipping or this can be delivered in person at a mineral show. Fine overall esthetics and rich density of Boltwoodite on matrix make this a top specimen for the specie.
Rounded complex Fluorite crystals are perched all over a jumbled mass of black Schorl. Some gemmy lustrous Goshenite (white) Beryl crystals are also present. The whole is especially esthetic and comes from a special find about 7 years ago. The major pockets found in the Erongos seem to be unique as each has an individual character and mineral mix that is different from other pockets. This is an especially attractive Fluorite specimen, far better in person, in fine condition and displaying well from any side or angle.
Okatjimukulu Farm 56, Karibib Region
3.1 x 3 x 1.7 CM (small miniature/ large thumbnail (toenail))
Flattened hexagonal crystal of deep purple zoned Apatite without matrix. From the finds several years back in the Karibib area of Namibia, this has an etched, frosted luster and good translucency. The crystal is not complete on all edges (typical for this find) but it is undamaged and shows complex recrystallization on some edges. The color is super intense in person, a very nice sizable purple Apatite.
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.
