LTH-33 - Azurite on Bayldonite - $ 1250 SOLD Tsumeb Mine, Otjikoto Region, Namibia thumbnail, 3.3 x 2 x 1.6 cm ex. Martin Lewadny
Terrific Azurites always come to mind when mentioning �Tsumeb� but this piece is shocking, ridiculous in color contrastr - it stands out from all other such azuyurite thumbers I have seen and is competition level, thus. These deep blue, sharp, rectangular prisms with classic lustrous, striated faces are set off beautifully against contrasting halloween-green Bayldonite (microcrystals). The Azurite crystals average 1-1.5 cm. This makes for a uniquely attractive toenail (large thumbnail or small miniature) specimen that is well-balanced, aesthetic, and very hard to come by. The association is rare. Ex. Sam Nasser collection.
MD-119974 - Bayldonite, Mimetite - - Archived Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia small cabinet, 5.8 x 5.5 x 5.0 cm.
5.8 x 5.5 x 5.0 cm. A very showy and unusual, coral-like, branching specimen of radial clusters of sparkly, blades and club-shaped crystals of bayldonite on tan mimetite from Tsumeb. A VERY INTERESTING and excellent combo piece form Tsumeb. The bayldonite is an oxidation alteration product of the mimetite. Ex. George Elling Collection.
MD-122945 - Cerussite, Bayldonite - - Archived Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia small cabinet, 7.3 x 3.5 x 3.0 cm.
7.3 x 3.5 x 3.0 cm. Glassy, cyclically-twinned cerussite crystals are aesthetically scattered on matrix covered with mounded, botryoidal, green bayldonite on this showy combination specimen from Tsumeb. Ex. George Elling Collection.
MD-147006 - Azurite, Malachite, Bayldonite - - Archived Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia small cabinet, 5.6 x 4.5 x 2.5 cm.
5.6 x 4.5 x 2.5 cm. An OLD-TIME and very showy Tsumeb specimen of highly lustrous, dark navy-blue azurite crystals and velvet malachite after azurite crystals on green bayldonite matrix. The sprinkling of tiny cerussite crystals is a very nice accent. Definitely from the upper oxidized zone of this famous and now-closed mine. This old-timer was in the Carl Bosch and Smithsonian Collections and includes Carl Bosch’s handwritten label. Carl Bosch was a very prominent European collector who lived from 1874-1940. The Smithsonian purchased his collection in 1965, which numbered 25,000 mineral specimens! The Bosch label number of 8065 indicates an old piece. It’s rich in crystals of high quality - he never collected junk.

7.5 x 4.8 x 4.1 cm. An old-time, classic and showy Cornwall specimen of green bayldonite crystals richly covering quartz matrix from the less well-known Wheal Carpenter Mine.

The contrast between the azurites and bayldonite is just so striking.
