Malachite Ps after Azurite
stock #18-AX-30-049
Flubspatgrube, Lichtenberg, Bad Stben, Franconian Forest, Franconia
Bavaria, Germany
5.9 x 3.3 x 2.7 CM (small cabinet/ large miniature)
price: $800
Dec 2018

A fine old Pseudomorph with a very well formed main crystal 2.4 CM tall. From the collection of Thomas Fitzpatrick, this is in excellent condition. I have not seen any other of this quality, the separation and contrast with the matrix is superb. There are some smaller crystals on the matrix most with some damage or are fully broken but these are not very obvious. The matrix is largely a dark red to brown Gossan with a few small Goethite spheres. On the bottom of the matrix there seems to be a small zone of Pseudomalachite as well.
Malachite - Primary crystals, classic locale
stock #15.1-1064-SM2923
Andrassy II. Mine, Rudabanya, Rudabanyai Mts.
Borosod-Abauj-Zemplen Co., Hungary
7.6 x 5.2 x 3.2 CM (cabinet)
price: $750
Worldwide mix summer

An old, well formed and crystallized Malachite from Rudebanya ex Charles Noll collection. The Malachite is quite lustrous and contrasts with the gossan matrix, but this is nearly all Malachite. This is also a well formed and fine Primary Malachite, not a pseudomorph. The luster is bright and satin like with clustered groups of prismatic crystals in spherical arrangements. In excellent condition, we do not know the vintage of this piece but the style is only seen in very old collections, and the locality has been mined since the copper age, it is one of the oldest mineral sites in Europe. Impossible to find specimens of this caliber today.
Malachite Slice of stalactitic nodule
stock #18.1-218
Katanga, Central Area, Katanga Copper zone
Shaba, Democratic Republic of Congo (Zaire)
5.4 x 4.5 x .5 CM (small cabinet/ large miniature)
price: $380
Spring update

Sharp and colorful pattern is well presented on both sides of this cross section of Malachite. Good polish and fine contrast in the banding that is "cauliflower" in form. This sort of quality slice was at one time more common but now is quite scarce. A modern classic.
Malachite replacing Azurite, Exceptional Tsumeb classic
stock #7XE-099
Tsumeb
Otavi-Bergland district, Oshikoto, Namibia
9.8 x 6.2 x 3.3 CM (cabinet)
price: $4900
Pre Holiday 2017

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 Balydonite 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.
Malachite -stalactitic form, cross section slab
stock #17.1-699
Katanga, Central Area, Katanga Copper zone
Shaba, Democratic Republic of Congo (Zaire)
5.6 x 3.6 x .4 CM (cabinet)
price: $280
Pre Holiday 2017

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.
Malachite - polished stalactitic section
stock #17.1-700
Katanga, Central Area, Katanga Copper zone
Shaba, Democratic Republic of Congo (Zaire)
6.8 x 5 x .4 CM (cabinet)
price: $350
Pre Holiday 2017

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.
Malachite ps after Azurite on Duftite, Mimetite etc.
stock #17.1-AXA-29-041
Tsumeb
Otavi-Bergland district, Oshikoto, Namibia
6.3 x 3 x 2.9 CM (cabinet)
price: $290
new june 17

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.
Malachite stalactite
stock #15.1-069
L'Etolle du Congo Mine - Lubumbashi
Katanga (Shaba), Democratic Republic of Congo (Zaire)
3.2 x1.6 x 1.1 CM (miniature)
price: $60
pre Tucson 2015 update

Small but perfect, an older stalactite of bright green Malachite from the Congo. The surface on all sides is a druze of sparkling malachite crystals that makes this very different from the usual smooth malachite stalactites.
