Tennantite
stock #13.1-238
Tsumeb
Otjikoto Region, Namibia
2.6 x 2 x 1.2 CM (thumbnail)
price: $190


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.
Fluorite with phantom zoning
stock #17.1-538
Okorusu Mine, Otjiwarango District
Otjozondjupa Region, Namibia
5.7 x 4.3 x 3.7 CM (small cabinet/large miniature)
price: $290
Spring 2020

Gemmy Fluorite cubes of blue-green color in a cluster on minimal matrix from Okorusu. This Fluorite has well defined inner phantoms of a darker violet-blue color and some cubes have a thin color zone extra near the outer edge. This specimen displays well from either side. The main crystals are prominent, sharp and clean, the only damage seen is minor on the outer edges where this was removed. Most Okorusu Fluorites are damaged, or the crystals are very tightly packed together, this is a nice exception. The mine has been inactive now for about three years and may be gone forever.
Amethyst- conjoined scepters
stock #17.1-663
Orange River, Namakwa
Karas Region, Namibia
2.1 x 1.4 x 1 CM (thumbnail)
price: $135
Spring 2020

A sweet thumbnail of sharp transparent Amethyst scepters that share a single stem. Both crystals show a double termination and grade to colorless lower down. From a find a few years ago at Orange River (Namibia), there were not many of these. In fine condition as seen, and a bit nicer in person too.
Epidote with Albite
stock #20.1-108
Amis Gorge, Brandburg Complex, Daures
Erongo Region, Namibia
6.8 x 4.8 x 3 CM (cabinet)
price: $330
Spring 2020

Sharp dark green free standing Epidote mixed with contrasting Feldspar (Albite) crystals. From a small find made almost 20 years ago, this is far above average and displays well from any angle. The condition of the crystals is very fine. Unlike any other Epidotes from Namibia and even quite unlike most any location anyplace else.
SOLD Malachite ps after Copper, ex Bosch, Smithsonian
stock #SOLD 15.1-947-(SM2855)
Tsumeb
Otjikoto Region, Namibia
5.7 x 3.6 x 2.5 CM (cabinet)
price: $0
Spring 2020

A super Pseudomorph with an outstanding, long provenance from the early years at Tsumeb. Radiating flower like structure that seems to be fully replaced by Malachite. Close to 100 percent Malachite, there is just a sliver of matrix on the base. An unusual form, as most Malachite Pseudos are clearly replacements of Azurite but this seems to be a replacement of a native copper structure. The bottom or underside has been sawn to make a flat spot so this sits perfectly on display. From the famed Carl Bosch collection (1874-1940) with his handwritten label and "code" to the Smithsonian institution and Charles M Noll, this has belonged in several major collections. The Bosch label code is described in the Mineralogical record, and if I can read this writing correctly it was obtained on July 17,1913 for 300 marks, a costly piece at that time. This is also a quite early specimen as the mine would not yet have reached level 6 at that date (it would eventually reach level 46) and this piece would have been found well before that date. There are relatively few specimens preserved from the earliest discoveries at the worlds greatest mineral locality. This is one.
Dioptase
stock #15.1-1037
Tsumeb
Otjikoto Region, Namibia
7.3 x 4.8 x 2.2 CM (cabinet)
price: $1500
Spring 2020

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.
Malachite on Quartz included by Shattuckite
stock #AX-4-234
Kaokoveld Plateau
Kunene Region, Namibia
6.3 x 5.9 x 4.8 CM (cabinet)
price: $1650
Spring 2020

Exceptional and super esthetic, the baby blue druse of clear Quartz crystals are richly colored by Shattuckite balls they have grown on and are included by. These contrast nicely with the bright green Malachite crystals. Looks even better in person, this from the find five years ago at Kaokoveld, nothing quite like this has come up since. A super display piece for any cabinet this Copper secondary specimen has top color, luster and form.
Azurite - rosette nodule
stock #8.AE-1015
Tsumeb
Otjikoto Region, Namibia
4.6 x 4.4 x 3.9 CM (miniature)
price: $240
Spring 2020

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.
