Rhodochrosite on Galena and Acanthite with Fluorite
stock #18-AX-22-109
Wutong Mine, Liubao, Cangwu Co. Wuzoh Pref.
Guizhou, China
6.6 x 5 x 3.8 CM (cabinet)
price: $560
Worldwide mix summer

An early find Chinese Rhodo with a deep rich red color set on a mix of Sulphides including Galena, Acanthite and Sphalerite. The early finds of Rhodochrosites from this region were associated with Silver minerals and sometimes native Silver as well. Later finds were much larger but did not have any Silver species. This has a good amount of Acanthite (Silver Sulphide) crystals and Silver rich Galena with melted look. The contrast is excellent and the Rhodochrosite crystals reach 2.9 CM. No more Rhodos are being found and this is a choice example of the earliest type from the upper zones.
Galena with Dolomite and Sphalerite

Ninth of September mine, Madan, Rhodope Mountains

7.7 x 4.7 x 3.6 CM (cabinet)

Bright metallic Galena with high luster is epitaxially encrusted with Dolomite in a very esthetic manner. Much of the Dolomite is in spherical form and is aligned on crystal edges. In super condition, the specimen is more impressive in person and the crystals have mirror brilliance on many faces. The Madan area mines have been the source of the worlds best Galena for several years, this specimen shows why these are so well respected as a very good value for quality.

Sharp undamaged rose Quartz crystals in a parallel position cluster. Individual crystals reach 3 CM and are all doubly terminated.

New Mexico, United States
5.8 x 4.2 x 4.4 CM (small cabinet/ large miniature)

A vuggy matrix hosts balls of crystalized Dundasite (white acicular needles in spheres) and bright blue and green Allophane. From the Juanita mine, in the famed Magdalena district of New Mexico, this is a moderately rich specimen that has several zones with tiny Dundasite balls. We do not see this material very often, this older piece was in the Hladysz collection.
Graphite - very fine, sharp crystals
stock #18.1-285
Olmsteadville, Minerva Township, Essex County
New York, United States
2.9 x 2.1 x 2 CM (thumbnail)
price: $525
Worldwide mix summer

A superb rosette crystal cluster of Graphite standing on matrix. At 1.1 cm across and with bright metallic luster this is a killer thumbnail in fine condition. Magnification finds one tiny edge contact but for this delicate mineral this is in amazing condition. Textbook form, and with fine esthetics, Graphite is not a rare mineral but well formed lustrous crystals are very rare. From finds in the late seventies, an excellent US classic specimen.
Thompsonite-Ca with Mesolite
stock #18-AX-6-041
Aurangabad
Maharashtra, India
5.8 x 4.1 x 2.6 CM (cabinet)
price: $290
Worldwide mix summer

A sparkling pink hemisphere of Thomsonite sits esthetically on a contrasting matrix. From a pocket found a few years ago, these pink Thompsonite were an exciting new find then, unlike any others with a covering of tiny needles of Mesolite that gave a nice luster. In fine condition, these are no longer available, and at that time very few were undamaged like this. A great addition to any suite of Indian or Zeolite minerals.
Brochantite on Malachite -historic
stock #1145-JM-3267
Frisco, San Francisco Mts. Beaver County
Utah, United States
5.4 x 4.4 x 3 CM (small cabinet/large miniature)

A vug of well protected Brochantite crystals ex John Marshall collection that has an excellent provenance. John bought this from Johnathan Smith (NYC mineral dealer) in Feb 1994. Jonathan had obtained this from the Alan Green collection who had gotten this from the Schortmann brothers at their famed sale in NYC in 1950, at the Hotel Lexington. This is the period where the Schortmans were selling minerals collected by Ed Over and Arthur Montgomery. All the original labels for this are included. In good condition, a cute Utah Copper specimen with pedigree.
