Arsenopyrite etc -
stock #8.1-170
Yaogangxian Mine, Yizhang County
Hunan Province, China
8.1 x 6 x 5.8 CM (cabinet)
price: $420
Worldwide mix summer

A very unusual style of Arsenopyrite from the famed Yaogangxian mine. A small amount of Muscovite matrix and associations of Fluorite (small clear purple crystals), Quartz and Calcite are typical in these multi specie specimens, but by far the majority is Arsenopyrite. Unlike the usual silver color, this has the bronze-golden hue that was only found in one zone about 15 years ago. Chipping and bruising on the outer edges is clearly seen but all the main crystals are intact and very sharp. As well as the unusual color, several crystals have unusual habits although most of the largest crystals are more usual forms most of which are in parallel position. Despite the edge damage this is a choice piece.
Quartz v. Herkimer
stock #18.1-292
Middleville, Herkimer County
New York, United States
8.3 x 6 x 7.1 CM (cabinet)
price: $250
Worldwide mix summer

A blocky matrix with druzy Quartz hosting several very clear, undamaged Herkimer type Quartz. The diamonds are mostly colorless but a few are the golden type, and all are very clear and lustrous. The largest crystal has a very big internal bubble cavity that holds unusual worm like petroleum inclusions. These are vividly fluorescent and have three distinct colors. A fine and impressive cabinet piece that is especially interesting under the microscope.
Cerussite -fine silky luster.
stock #18-AX-18-051
Touissit, Touissit-Bou Beker Dist., Jerada Province
Oriental Region, Morocco
5.7 x 4.3 x 3.2 CM (small cabinet/large miniature)
price: $450
Worldwide mix summer

A remarkable and fine Cerussite from Touissit with at least 3 generations of crystals and no matrix. The largest are the silky type twins that are optically transparent from some angles and almost opaque from others as they have a "cats eye effect". These contrast with both a black druzy (heavily included by Galena) and small colorless Cerussites. Remarkably this is fully undamaged and pristine from all angles. Touissit is sadly long closed but did in its day produce some of the worlds best Lead secondary minerals and a few of these unique silky luster Cerussites,. This is a very choice example from any angle, and better in person.
Rhodochrosite on Galena and Acanthite with Fluorite
stock #18-AX-22-109
Wudong mine, Liubao, Cangwu Co. Wuzoh
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
stock #18 AX-27-091
Ninth of September mine, Madan, Rhodope Mountains
Smolyan Oblast, Bulgaria
7.7 x 4.7 x 3.6 CM (cabinet)
price: $380
Worldwide mix summer

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.
Rose Quartz - large doubly terminated crystals
stock #18 AX-7-169
Ilha claim, Taquaral, Itinga
Minas Gerais, Brazil
5.3 x 4 x 2.8 CM (small cabinet/ large miniature)
price: $1100
Worldwide mix summer

Sharp undamaged rose Quartz crystals in a parallel position cluster. Individual crystals reach 3 CM and are all doubly terminated. Very glassy luster, good color and with just a small contrasting Quartz matrix. On close exam some curving faces are seen. Choice display piece that has strong display impact from several angles. Better in person too
Dundasite with Allophane
stock #18-AX-12-584
Juanite Mine, Magdalena
New Mexico, United States
5.8 x 4.2 x 4.4 CM (small cabinet/ large miniature)
price: $90
Worldwide mix summer

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.
