Copper in Calcite
Onganja Mine, Windhoek District
4.9 x 3.8 x 3.5 CM (miniature)
An exceptional (and very unusual) Copper in Calcite from the great Onganja Mine. A large sharp transparent Calcite 3.8 CM across sits on and is included by Copper. The matrix is partly Copper, Malachite and Chalcotrichite. The Calcite is unlike most from Onganja as it is a simple modified rhomb without the complex habits or twinning that is typical from here. This displays well from most any angle, in very good condition with only very minor rub spots. The Onganja mine was once a prolific source of fine Coppers, Cuprites etc but the Calcites were always especially rare and sought after. The mine has been closed and flooded for years. This specimen is quite striking in person and a significant Copper.
From the exciting new finds at the San Carlos Mine, choice gem clear Wulfenites resting on glass clear Calcites and yellow Mimetites balls. The Mimetites are also included inside the Calcite, especially impressive under magnification. In perfect condition by naked eye, micro damage can be seen at 20X magnification, this is certainly not significant and is essentially perfect especially for this delicate mineral habit of the beveled edge blades. We have handled a lot of this find and this habit, color and association is unusual and very esthetic. Better in person too.
A super esthetic stack of perfect Adularia crystals in epitaxial arrangement hosting gem clear Titanites. Some selective coating of Chlorite on crystal faces of the Adulariaadds some contrast as well. This is a 360 degree piece it looks fine on all sides and has a strong esthetic arrangement. The main Titanite is 8mm perfect, gem clear flat prism with bright luster. A few tiny Quartz crystals are mixed into the matrix as well, overall a super fine arrangement of Alpine species.
A fine, vintage classic Epidote prism in perfect condition with outstanding provenance. Ex Clarence Bement, American Museum of Natural History, Jeff Glover and the Larry Conklin collections with other labels as well. The slender prism is transparent, sharp, lustrous and well terminated. This sort of Epidote is rare from Switzerland and this one (donated to AMNH in 1910) was collected well over 100 years ago. The Bement collection was at one time considered the finest ever assembled in the Americas, it later formed the heart of the AMNH collection. Bement pieces are rarely available and this Swiss Alpine specimen is a choice one. One last note there are discrepancies among the old labels regarding the location, several list Zermat as the source, but research by later collectors indicates this is a Grisons (Grischun) piece.
Sphalerite on Quartz
Clinton, Onieda County
3.5 x 2.7 x 2 CM (small miniature/ large thumbnail (toenail))
A bright lustrous Sphalerite crystal perched above a sparkling Quartz matrix. From an important 1987 find in Clinton, NY. this is an excellent clean example. The Sphalerite shows the complex form that is typical with multiple twinning and is translucent, light passing through gives a rich yellow to rootbeer color. Can be trimmed to a thumbnail if desired. A modern classic from the Northeastern USA not often available.
Daoping Lead-Zinc Mine, Yangshao
Guangxi Autonomous Region,
5.1 x 4 x 3.1 CXM (small cabinet/ large miniature)
A perfect, killer miniature. Top intense color, brilliant luster and elegant form in an undamaged specimen. Even though many of these were found since the first finds in 2000, very few were this well formed and esthetic. This specimen comes from a small recent pocket, that gave the first Pyromorphites of any quality in more than 4 years. These are modern classics and the best Daoping Pyros like this one are quite prized as they stand out from the average pieces. This presents well on every side and angle, the crystals show several habits but are mostly elongated freestanding hexagons some with central hoppers. The smaller, slender crystals are a little less bright green and are also perfect in radiating clusters. Minimal matrix, a perfect large miniature with a display impact much larger than this size. It is incredible this is so perfect and undamaged, even better in person.
A neat miniature hosting a fine Dauphine twin Quartz that has gem clear transparency. A New England classic, these are often compared with the well-known Colorado specimens but are quite different in person. the matrix is well crystallized Amazonite, with the blue green color most desirable from New Hampshire. Ex Ernie Schlichter collection, this was collected by him in the heyday of the Government pit digging. The luster is excellent and glassy on the Quartz and a pleasant matte finish on the Feldspars making a nice contrast.
These are from an old stash and are not at all common on the market
Fluorite - new find
Fluorite Quarry, Jebel tighemi, Taourirt, Taourirt province,
l Oriental Region,
5.1 x 4.6 x 3.3 CM (small cabinet/ large miniature)
A very fine, ultra clear and sharp pair of Fluorite cubes on matrix from the new find of Moroccan Fluorites. This find has produced a lot of larger, somewhat crude cubes, most being opaque to translucent only. Very few have come out with this perfection and transparency. No damage and displayable from almost any angle, the Fluorites are well exposed and just barly connected to the matrix being perched on small pedestals of crystallized matrix. The Fluorite itself does look a bit like a fine Llamas Quarry piece but is also differnt on close exam. Some faces show a slight frosting that under magnification shows a beautiful recrystallized texture with a melted look. The matrix is easily seen right through the Fluorite.
