Incredible form, with large sharp crystals showing classic Azurite shape covered by silky Malachite. In exceptional condition, the biggest crystal in this cluster is textbook habit, doubly terminated and 6.3 CM long. A few areas of Azurite remain, with Bayldonite and Olivenite present as well. Ex N.Collins and A. Edwards collections. Impressive display impact, in clean undamaged condition, this is a top quality Tsumeb piece likely from the 1920-30 vintage years.

Sections of stalactitic Malachite can be quite esthetic, especially when the form is more complex and with good color banding. This is an excellent example cut from materials collected in the 1990s. This style is now becoming rare with the "cauliflower" form. Complete edge rind all around, and polished on both sides.

Sections of stalactitic Malachite can be quite esthetic, especially when the form is more complex and with good color banding. This is an excellent example cut from materials collected in the 1990s. Far better quality and form than average for this sort of slab. The double eye on this piece is especially striking. Polished on both sides but the "back" as seen was near to top knob of the malachite form and so has much more rind. Complete with great form and contrast.
A choice and attractive Tsumeb specimen. A flower-like cluster of sharp Malachite pseudo after Azurite crystals is nicely perched on mounds of sharp well crystallized green Duftite. These are sizable (for the specie) and they are perched on what looks to be Mimetite and some Cerussite with a few gem clear Calcite crystals, a tuft of Rosasite and a few other micros of related species. This is the kind of elegant and complex mixing of diverse species and crazy chemistry that makes Tsumeb minerals so incredible. In fine condition, displays well and a real treat under the microscope.

An nice, affordable pseudo from Morenci, The crystals reach 1.6 CM and show some of the original Azurite color but are mostly now replaced by the Malachite green. This is an older specimen collected over 50 years back yet in excellent condition with no visible damage.
