MD-118200 - Stranskiite, Leiteite - - Archived Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia thumbnail, 2.4 x 0.9 x 0.5 cm.
2.4 x 0.9 x 0.5 cm. An extremely fine DOUBLE RARITY thumbnail from Tsumeb. A cyan-blue crust of microcrystalline stranskiite is jauntily perched atop a translucent, pearlescent, silky leiteite. Stranskiite and leiteite are ULTRA RARE zinc arsenates and Tsumeb is the Type Locality for both species.
MD-167089 - Leiteite - - Archived Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia thumbnail, 1.5 x 0.8 x 0.3 cm.
1.5 x 0.8 x 0.3 cm. Leiteite is an ULTRA RARE zinc arsenate and Holy Grail rare species for the famous and now-closed Tsumeb Mine, which is the Type Locality. This showy, highly lustrous, pearlescent thumbnail features a foliated mass characteristic to this rare species. Highly representative and desirable for the species and locality.
MD-170552 - Ludlockite, Leiteite, Stottite, Germanite - - Archived Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia small cabinet, 6.2 x 5.1 x 4.0 cm.
6.2 x 5.1 x 4.0 cm. An EXCELLENT Tsumeb specimen consisting ENTIRELY of ULTRA-RARE, Holy Grail mineral species. Bright orange sprays to 7 mm of felt-like, acicular ludlockite needles are nicely scattered on a matrix of SOLID germanite ore. A centrally located, 1.3 cm vug hosts a 2.5 mm leiteite (the tall prismatic crystal with gem tip, slightly included with red ludlockite) and a gemmy, sharp, brown, tetragonal pseudo-octahedral, approximately 2mm stottite crystal (not x-rayed but confirmed visually by Drs. Bill Pinch and Terry Seward among others). Tsumeb is the Type Locality for ALL 4 species and stottite, an iron germanium hydroxide, is known ONLY from Tsumeb. An outstanding Tsumeb combination piece of ultra-rare species from the Rob Smith Collection.
MD-177574 - Ludlockite, Leiteite - - Archived Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia thumbnail, 2.8 x 1.8 x 1.2 cm.
2.8 x 1.8 x 1.2 cm. This specimen is clearly Leiteite in form, and yet it has a bright umber-red color to it! The cause is due to minute dispersed inclusions of Ludlockite. Ex. Marshall Sussman Collection.
MD-181679 - Leiteite, Ludlockite - - Archived Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia thumbnail, 1.9 x 1.2 x 0.8 cm.
1.9 x 1.2 x 0.8 cm. This is a fine combination thumbnail features a pearlescent, translucent leiteite plate on top of a mass of hair-like, burnt-orange ludlockite needles.
MD-248019 - Leiteite - - Archived Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia thumbnail, 3.0 x 2.4 x 1.2 cm.
3.0 x 2.4 x 1.2 cm. Leiteite is a very rare zinc arsenate mineral species named in 1977 from a single aberrant specimen found at Tsumeb, and then found sparsely in a few more pockets in the so-called germanium levels of the final and deepest part of the mine. In all the previous years at Tsumeb, none had been found until the miners went down to a third oxidation zone and encountered a bizarrely germanium-rich zone from which new species came in profusion. Ludlockite and leiteite among the most well known. Most of the examples of these species are fibrous. This specimen, however, shows robust crystal faces, and real crystal form. It is also extremely translucent and attractive, whereas most leiteite is opaque, fibrous, and looks more like white asbestos than a mineral specimen. This is a superb example of the species and an important specimen of good size for a leiteite crystal. Ex. Eric Asselborn Collection.
MD-266990 - Ludlockite, Leiteite - - Archived Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia small cabinet, 5.2 x 3.7 x 2.3 cm.
5.2 x 3.7 x 2.3 cm. Ludlockite and leiteite are two of the very rare and highly desirable species for which the Tsumeb Mine is the Type Locality. To get both in a fine specimen on rich germanite ore is a triple bonus. Bright, burnt orange ludlockite hairs are richly scattered on highly lustrous, colorless plates of leiteite. This combination was found but rarely in the final days of Tsumeb. Ex. Rob Smith Collection.
MD-38542 - Leiteite - - Archived Tsumeb, Otjikoto (Oshikoto) Region, Namibia small cabinet, 7.7 x 1 x .4 cm
An elongate specimen of fibrous leiteite, unusual in that both ends seem to be terminated (insofar as this style of mineral terminates, that is). It is an unusually large and showy specimen, without breaking the bank to add to a good Tsumeb suite! These were found towards the end, on the "germanium levels" deep in the mine. 7.7 x 1 x .4 cm
RARE08-2-77 - Ludlockite in Leiteite - $ 3000 SOLD Tsumeb Mine, Tsumeb, Namibia (TYPE LOCALITY for BOTH SPECIES) thumbnail, 2.8 x 1.8 x 1.2 cm ex. Marshall Sussman
I have simply never seen another piece like this. It is clearly Leiteite in form, and yet it has a bright umber-red color to it! The cause is due to minute dispersed inclusions of Leiteite. The piece is unique and stunning, as you can see. (TYPE LOCALITY for BOTH SPECIES)
ZR20 - Leiteite - $ 1250 Tsumeb Mine, Tsumeb, Namibia small cabinet, 7.7 x 1 x .4 cm ex. Martin Zinn
An elongate specimen of fibrous leiteite, unusual in that both ends seem to be terminated (insofar as this style of mineral terminates, that is). It is an unusually large and showy specimen, without breaking the bank to add to a good Tsumeb suite! These were found towards the end, on the "germanium levels" deep in the mine.
