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!

  • 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!

  • Here is an interesting variation! This plate has several elongated crystals on it that once were azurite but have been replaced by malachite.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!

  • 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.

  • 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!

  • 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. The faces on the cerussite crystals range from very sharp windows to sort of rounded, melted looking faces. Interesting, quality specimen!

  • 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!

  • 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.

  • 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!

  • 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.
