Item #27489 Dioptase, Plancheite, Calcite 4.3x2.4x1.9 cm Largest Crystal Size: 1mm $85.00 Tsumeb Mine Otjikoto Namibia Here is a different and beautiful one. This specimen shows loads of tiny, emerald-green dioptase crystals that have foremed on pearly-white calcite (or dolomite) crystals. The dolomite in turn formed on a layer of sky-blue, radiating plancheite crystals. Here and there the fuzzy balls of plancheite can be seen and particularly around the edges where the zoned appearance of the plancheite is obvious. Just like in mindat!
Item #27487 Malachite, Chrysocolla 7.0x4.3x2.5 cm Largest Crystal Size: 8mm $45.00 Tsumeb Mine Otjikoto Namibia To be hones, I don't actually know WHAT this specimen is over all. The main feature is a number of epimorphs of a bluish mineral (chrysocolla?) forming epimorphs over pseudo's of some former mineral. Looks great but a little mystery!	Item #27484 Linarite, Cerussite 4.1x2.8x1.4 cm Largest Crystal Size: micro $85.00 Tsumeb Otjikoto Namibia This fragment of cerussite is loaded with vugs that are lined with deep blue, acicular tufts of linarite.

The crystals are either bared or, in some cases, partially coated with copper mineralization. The copper mineralization is mostly malachite ( the back is thick malachite crystals) but there is also a blue, un-identified mineral. I am not sure what it is but it really adds interest! Lots to look at!
Item #27479 Cerussite 3.8x2.7x2.8 cm Largest Crystal Size: as above $65.00 Tsumeb Mine Otjikoto Namibia A ghostly-white, star-shaped cerussite twinned crystal aggregate with very pointy "wings".

The matrix appears to be a mixture of cuprite, chalcocite(?) and other sulphides. Interesting locality piece!	Item #27472 Copper, Calcite 4.7x3.1x2.5 cm Largest Crystal Size: 1mm $65.00 Tsumeb Mine Otjikoto Namibia This specimen shows an open seam of calcite crystals laced through with sharp, bright copper crystals. Very little tarnish! There are also copper crystals on the side and back of the matrix. A less common specimen from Tsumeb!	Item #27471 Cerussite, Hemimorphite, Smithsonite 7.4x3.6x3.3 cm Largest Crystal Size: c-8mm, s-4mm, h-0.5mm $85.00 Tsumeb Mine Otjikoto Namibia This is an interesting and different one! It shows a vug of black smithsonite crystals with a couple of black cerussite crystals sitting in the vug. All through the smithsonite crystals are patches, groups and ridges of white-colourless, acicular hemimorphite. The hemimorphite has been analysed. Looks great AND is unusual!	Item #27468 Dolomite, Hematite 6.7x4.1x2.4 cm Largest Crystal Size: 20mm $75.00 Tsumeb Otjikoto Namibia This is a very elegant specimen! It is a thin growth of egg-shell-like dolomite that appears to be an epimorph after calcite or some other mineral. I've shown top and bottom views to try and show the hollow nature of the epimorph. The crystals are preferentially coloured brick-red on one side by particulate hematite. Really nice piece!
Item #27466 Wulfenite, Dolomite 11.1x9.2x4.5 cm Largest Crystal Size: 8mm $225.00 Tsumeb Otjikoto Namibia This plate of slightly-pink, dolomite crystals is sprinkled with orangey wulfenite crystals. The wulfenites are thick tabular with a prominent bevel around the edges. There are lots of crystals on the back, as well but the biggest ones are damaged. This is the viewing angle. A handsome specimen!	Item #27462 Mimetite 6.2x4.5x4.5 cm Largest Crystal Size: 3mm $120.00 Tsumeb Mine Canada Here is a striking specimen! This dark brown matrix has a large cavity in the front of it that contains loads of clusters of vibrantly contrasting, bright yellow mimetite crystals. There is also a dark green mineral associated with the mimetite, perhaps duftite or mottramite. Displays well!	Item #27461 Mimetite 3.5x2.4x2.4 cm Largest Crystal Size: 3mm $35.00 Tsumeb Mine Otjikoto Namibia Sparkling, highly lustrous, sharp crystals of mimetite cover most of the top of this matrix.

This plate has several elongated crystals on it that once were azurite but have been replaced by malachite. While this is not unusual, the pseudo's also have tiny calcite crystals preferentially deposited on certain of the pseudo faces and then a final deposit of quartz crystals has given the crystals a cap. Interesting!	Item #27452 Cerussite 4.8x4.1x3.1 cm Largest Crystal Size: as above $160.00 Tsumeb Mine Otjikoto Namibia These crystals are three members of a sixling twin that was attached to matrix on the bottom. The crystals are very gemmy and lustrous with a smoky-colourless colour. (Can I actually say that?!). sits perfectly for display.
Item #27451 Pyrite 3.3x3.1x2.4 cm Largest Crystal Size: 25mm $45.00 Tsumeb Otjikoto Namibia OK, this is an aesthetically challenged specimen but it is such an unusual piece for Tsumeb, I thought I'd include it. It is composed of two composit pyrite crystals intergrown with black sulphide-y minerals. I think the black minerals interrupted the pyrite growth. It looks way better in person. Interesting and unusual!	Item #27448 Cerussite 3.9x2.6x2.3 cm Largest Crystal Size: 19mm $75.00 Tsumeb Mine Otjikoto Namibia A cluster of colourless, gemmy cerussite crystals on a matrix that is mostly composed of granular cerussite with some little prismatic mimetite crystals and other minerals here and there.

Great-looking!
Item #27444 Cerussite 3.0x3.0x1.6 cm Largest Crystal Size: as above $75.00 Tsumeb Mine Otjikoto Namibia A pure white, perhaps with a slightly irony tint, of bladed sharp cerussite crystals. Not sure why they are white but they are! There is one tiny chipped spot on the side that shows that the crystals are, in fact, gemmy inside and the white coating is a white veneer. Great looking!	Item #27443 Cerussite 3.1x2.8x2.3 cm Largest Crystal Size: 24mm $120.00 Tsumeb Mine Otjikoto Namibia This is a cluster of gemmy, grayish pointy cerussite crystals that are arranged in one larger, twinned cluster.

A cluster of anglesite crystals, all of which are very, very good! The crystal at the center is a singly terminated lustrous crystal and there are larger and smaller, fairly gemmy crystals on either side of it. Displays very well!	Item #27440 Calcite 8.0x8.3x3,3 cm Largest Crystal Size: 13mm $65.00 Tsumeb Mine Otjikoto Namibia OK, you pseudomorph collectors. This matrix has a number of pseudos that appear to be pink calcite crystals after a larger bladed mineral. Just quartz crystals, iron oxide and calcite crystals elsewhere on the siliceous matrix. Interesting and attractive.
Item #27439 Mimetite, Calcite 5.0x3.6x2.7 cm Largest Crystal Size: 2mm $45.00 Tsumeb Mine Otjikoto Namibia This gossan matrix is all held together by calcite crystals all through it. Amongst the calcite crystals are rounded botryoids of radiating willemite crystals that appear like light yellow balls. Different!	Item #27438 Smithsonite 5.7x3.4x3.3 cm Largest Crystal Size: n/a $75.00 Tsumeb Mine Otjikoto Namibia Light green-bluish botryoidal smithsonite composed of small curved crystals, lines a vug in this light coloured matrix. Very attractive and unusual colour!	Item #27436 Cerussite, Smithsonite and ? 5.5x4.4x2.3 cm Largest Crystal Size: c-7mm $85.00 Tsumeb Mine Otjikoto Namibia This piece is covered on top and bottom with light green smithsonite crystals and scattered, sharp, greyish cerussite crystals. The cerussite crystals are the kind of cyclic twins that appear to be hexagonal bipyramids. The smithsonite crystals are simple, zones rhombohedra. There is a patch of an umusual mineral on two places on the specimen. At first I thought that it looked like a splash of native silver. Very silvery-metalliz. Upon closer examination, though, it is not metallic but silvery-micaceous. I guess it could be a mica or something more exotic? Interesting!	Item #27435 Mimetite, Quartz, galena, etc 4.5x3.7x3.2 cm Largest Crystal Size: 2mm $45.00 Tsumeb Mine Otjikoto Namibia The front of this galena-chalcocite matrix is a concave opening that protects a lining of many sharp, sparkling mimetite crystals. The mimetites are hexagonal prisms with horizontal stria and sharp pyramidal terminations. Beautiful crystals!
Item #27434 Calcite, Willemite 3.9x3.6x2.1 cm Largest Crystal Size: c-5mm, w-1mm $45.00 Tsumeb Mine Otjikoto Namibia This is an odd one. The top of the piece is mostly calcite crystals that grade from brownish to colourless. They are mostly covering a botryoidal white mineral, with pearly lustre, that I believe is willemite. As well, there are small hexagonal willemite crystals around the edges. Lightly fluorescent.	Item #27433 Tennantite, Quartz 5.3x3.4x1.1 cm Largest Crystal Size: 12mm $45.00 Tsumeb Mine Otjikoto Namibia This small plate has a number of tennantite crystals nestled amongst the 2mm or so quartz crystals and 3mm or so dolomite crystals. The tennantites are fairly well formed but, unfortunately, the largest one has a chip out of the upper part of it. Displays well1	Item #27432 Cerussite, Duftite, Mimetite 3.7x3.9x2.6 cm Largest Crystal Size: c-5mm, mim-5mm $65.00 Tsumeb Mine Otjikoto Namibia This is a very cool specimen.
