SOLD Cornetite with Chalcopyrite, Malachite, Cuprite
stock #SOLD 7.AE-308
L Etoile du Congo Mine (Star of the Congo), Lubumbashi
Katanga (Shaba), Democratic Republic of Congo (Zaire)
11.6 x 6.2 x 3.3 CM (cabinet)
price: $0
Fall 22

A super unusual and a very esthetic Cornetite mixed with iridescent Chalcopyrite - which is not a common association. The color could be described as peacock blue and the iridescent Chalco adds to that as well. Also, there are several zones of Malachite in small balls and clusters, some of which are clearly pseudomorphed after Cuprite crystals. The Malachite shows the dodecahedral shape of the original Cuprite crystals and are very distinct under magnification. The Cornetites from the Shaba Crescent are the world's best for the specie and this locality is pretty much the only place on earth where such sizable pieces can be found. An older specimen, we have not seen anything new of this quality and size for years.

Analcime on Natrolite etc.
stock #17.1-455
Poudrette Quarry, Mont Saint-Hilaire
Qu├ębec, Canada
5.8 x 4.7 x 3.8 CM (cabinet)
price: $320
Fall 22

A classic from the famed Mont Saint-Hilaire which is perhaps the world's most important Alkaline Pegmatite. This locality has so many outstanding and unusual combinations of minerals. This specimen features a 3.4 CM diameter Analcime crystal that is sharp, glassy and complete. This rests on several other minerals perhaps the most prominent are Natrolites some of which have pseudomorphed after an earlier mineral. A nice example of Saint-Hilaire Alkalai minerals.

Duftite on and in Calcite
stock #7.AE-018
Tsumeb
Otjikoto Region, Namibia
5.3 x 4.6 x 2.3 CM (small cabinet/ large miniature)
price: $280
Fall 22

A nice combination specimen from Tsumeb. The Calcite is in two generations; the fist is a stack of discrete rhomb crystals that have been coated by green Duftite. The second generation is of tiny clear Calcite crystals that grew over some of the Duftite and add a nice sparkle. Quite esthetic and displays well despite few clean cleaves. Nice color and quality for the price.

Fluorite
stock #13.1-149
Gordonsville Mine, Carthage, Smith County
Tennessee, United States
5.2 x 4 x 3.3 CM (small cabinet/ large miniature)
price: $150
Fall 22

Nice Gordonsville Mine (Elmwood) Fluorite. Zoned outer edges and a nice clear corner cap over growth on the main cube. These have become less available and more expensive in the past few years though they were common some time ago. These are classics already and the corner overgrowth on this one is textbook perfect.

Quartz - Prase type, with Hedenbergite inclusions
stock #10.1-229
Serifos Island, Cyclade Islands
South Aegean, Greece
7.8 x 2.4 x 1.3 CM (cabinet)
price: $400
Fall 22

Perfect, sharp and well-formed classic habit for a Serifos Quartz. The two side crystals are also sharp, slender and perfect. This locality has been famed for many years and still occasionally produces fine Quartz, but such clean tips have always been rare.

Mimetite with Malachite ps after Cuprite
stock #19.1-984
Tsumeb
Otjikoto Region, Namibia
8.1 x 6 x 2.4 CM (cabinet)
price: $750
Fall 22

Colorful and classic Tsumeb specimen with flower-like sprays of light yellow Mimetite on a field of green Malachite balls. The specimen is quite richly covered and the Mimetite is well-distributed. One of the many reasons that Tsumeb is such a revered locality is the amazing diverse combinations of mineral species, elements, alterations and forms that are sometimes very esthetic. This is a choice example of these lead and copper species together. In very good condition as seen. The surface has hundreds of Malachite balls which with close exam are seen to be in the shape of Cuprite crystals (dodecahedral form) covered and altered to Malachite with a botryoidal surface. This alteration is very much like the classic Chessy, France pseudomorphs but with a different texture. An excellent display quality specimen with lots to see on it.

Rhodochrosite with Quartz - vintage, classic specimen
stock #AX-35-459-(1407)
Baia Sprie
Maramures, Romania
9.1 x 7.4 x 3.8 CM (cabinet)
price: $950
Fall 22

Very fine Rhodochrosite on Quartz from the famed Wallace Gould Levison (NYC, USA) collection obtained by trade in 1894 from a Mr. Gruzig. The large matrix holds an open cavity with Rhodochrosite balls and sparkling small crystals mixed with Quartz. The original locality listed in Levisons collection ledger calls the locality Sieben Geberge in Hungary. He later amended his label to Felsobanyo, Hungary. This is now Baia Spirie, Romania. This period was a dynamic epoch in the Austrio-Hungarian Empire, so localities were often renamed as borders, languages and nationalities changed. No matter the locality changes, this is a very well-formed specimen in excellent condition. The original Levison handwritten label is attached to the piece, and we also include a photocopy of this page from his collection notes/ ledger. Levison was an important American mineral collector and inventor (first patented movie camera etc). This piece is his number 1407 from a collection that eventually reached over 5,500. In addition to being an attractive specimen this has well-documented provenance and a good historic pedigree. Better and a little more vivid in person.

Scheelite on Muscovite
stock #AX-5-066
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan Province, China
7.6 x 5.8 x 3.9 CM (cabinet)
price: $1450
Fall 22

Fine deep orange-red Scheelite crystal on Muscovite matrix. This is an early specimen, ex Shields Flynn collection, that is the most rare and desirable color for Chinese Scheelite. The crystal is 3.2 CM across and lustrous, translucent to transparent. One lower corner has contacts where Muscovite blades grew into the Scheelite, the rest is in excellent condition, sharp and undamaged. As far as I know all Scheelites worldwide are fluorescent, usually a whitish blue. This one is more a yellow to orange color and is quite unusual. Overall a bright and attractive specimen with exceptional color.
