Galenobismutite on Quartz
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
6.4 x 5 x 3.9 CM (small cabinet/ large miniature)
A very fine rarity from Yaoganxian, this is a rich, significant and esthetic Galenobismutite. It is the most attractive specimen of the specie that I have seen. Ex Shields Flynn collection, obtained from Bert Ottens some years ago who confirmed the specie, this is superb from this famous classic location. This visually looks much like a fine Boulangerite and would be an excellent specimen of that but the analysis shows this to be much more rare. It seems that there may be other specimens labeled as Boulangerite that are Galenobismutite. The matrix is a cluster of clear Quartz crystals showing two generations. The metallic needle crystals are in large masses on several faces of the specimen and are also included inside the largest, earlier Quartz prisms. In excellent condition. Mindat lists Galenobismutite from Yaogangxian but there is not yet a single photo from there.
Cuprite - classic Tsumeb
5.1 x 4.2 x 3.2 CM (small cabinet/ large miniature)
A rich array of stacked, aligned crystals of Cuprite from Tsumeb. Cuprite is not rare from this mine but this is an unusually esthetic and sizable cluster of crystals, the largest to almost 1 CM. Under average lighting this looks very dark, almost black, but with strong lighting the more red color is seen. Most of the crystals are translucent and can glow with a good backlight. In excellent condition the matrix hosts a few isolated crystals but the main pure cluster of Cuprite is a full 5 CM across. The epitaxial arrangement of the Cuprite (most of these are Octahedra and aligned) is also very evident in person. A much better than usual Cuprite from Tsumeb, this is ex Charles M. Noll collection.
A very well*-formed example of Goethite crystals on a Smokey Quartz prism. The Quartz is unusual in that it is doubly terminated and in very good condition. The "Ongeite" is in blocky curved rhombic crystals and stacked groups. In much better condition and distinct form that we usually see, this is from an older Northeast collection obtained from Lazard Cahn (no label however) in the early half of the 20th century. A distinctive and classic American specimen these are unlike anything else from any other locality. A few areas of the Quartz have red staining that is also typical of this region.
Chalcocite - iridescent crystals
Flambeau Mine, Ladysmith, Rusk County
5.3 x 3.8 x 2.8 CM (small cabinet/ large miniature)
A cluster of bright and well-defined crystals with rich patina. Choice modern classic from the Flambeau Mine, these crystals reach to over 3 CM and are complexly intergrown. There have only been two great finds of Chalcocite crystals in the USA, the old Bristol Copper mine in the 1840-50 era and the Flambeau in the mid 1990's. Both locations are finished and will never produce again. The hexagonal disk-like habits on this are twinned crystals which are in excellent condition. Close exam finds only a very small bruise (3mm) and a contact neither of which is easy to spot or distracting. Several smaller crystals seem to be untwinned, there is no matrix. Pure Chalcocite with red, blue and purple hues showing well. This does not have any of the unstable pyrite that sometimes causes decomposition, this is far better than 99.9% of this famed find. Displays well from most any angle.
Apatite on Albite with Clinochlore
Tormiq Valley, Haramoush Mountains, Skardu District
5 x 4.1 x 4.4 CM (small cabinet/ large miniature)
Compound crystal of Apatite CaF 4.7 CM across is perched nicely on a snowy white Albite matrix sprinkled with Clinochlore. Well-defined faces, good luster and with nice striations, the crystal is a cream-yellow color and transparent in parts. Good fluorescence also. An alpine style habit and association, this from Pakistan though, it really looks like a fine Austrian piece. Older labels included, Ex Nick Carruth (Cornwall, UK) David Crawford and Charles Noll (USA). In very good condition no obvious damage and better in person too.
Mauldin Mountain, Montgomery County
5.1 x 3.3 2.3 CM (small cabinet/ large miniature)
An isolated, distinct hemisphere of Wavellite on contrasting matrix. A USA classic from Mauldin Mountain, the sphere is composed of tightly packed crystals that have a nice sheen in person. In excellent condition, the color is a little deeper than the photos show. An older specimen, these Wavellites are considered by many as the best from the USA and yet still quite affordable for a nice piece.
A single sharp and glassy Epidote crystal with perfect termination from the famed VAG Mine, (aka Belvidere Mt./ "Eden Mills" Vermont), find made over 35 years ago. This zone produced several very fine crystals including the largest complete Epidotes ever found in the USA (and perhaps the world). This specimen is much smaller than the giants but has no repairs (the big ones were broken). Almost never available except in older collections, this is in perfect condition, partly transparent with well-defined striations.
Impressive structure and textbook form on these hoppered Halite crystals from the remarkable finds at Polkowice (Poland). The Halite is colored green by the rare mineral Tolbachite and also has inclusions we are told of some Bitumen, Sulphur and Covellite. Inclusions aside these are amazing in form and well-presented as sharp, undamaged modified cubes that show the incredible natural structure perfectly. This is from a fairly recent find that we consider to be one of the best in the mineral world, with great esthetics and an excellent value.
