Wulfenite on Mimetite -New find
San Carlos Mine, Municipio de Maunuel Benavidas
3.2 x 2.6 x 1 CM (small miniature/ large thumbnail (toenail))
A killer toenail of fine orange-red Wulfenite with perfect, textbook form. The contrasting matrix of Mimetite adds a great contrast. From the new find at San Carlos Mine, this is unusual as it is perfect, undamaged and well trimmed. This was a small but important find, the mine previously was known only for some fine Vanadinites decades ago, these new Wulfenites were a big surprise. This was the best in this size that we saw and it is much more impressive in person. Can be trimmed to a fine competition grade thumbnail, but certainly looks fine as is.
Daybreak Mine, Spokane County
5.5 x 4.2 x 2.2 CM (cabinet)
A fully crystallized plate of Autunite from the old sixties vintage finds at the Daybreak Mine. Now considered American classics, this piece has been stabilized to keep it from crumbling as many did. As the Autunite looses water in dry air they tended to alter to Meta Autunite and fall apart. Vivid fluorescence as was typical for these, this specimen came from the Les Hitchings collection, obtained in 1970. Good color and form in excellent condition.
Axinite with Prehnite
Grey Cloud Claim
5.5 x 3 x 3 CM (small cabinet/ large miniature)
A colorful and unusual Canadian specimen, sharp glassy Axinite crystals -some of them gem clear- contrast with bright Prehnite crystals. This looks just like some classic Alpine European specimens (Bourg de Oissans etc) but also a bit unique too. The Prehnite crystals show curved faces and are colorless, white and light green some also have a chlorite coating adding more color. Ex Les Hitchings, this was collected in 1960. Close exam finds some edge chipping so this is not fully perfect but it is a very esthetic and well crystalized specimen the best I have seen from this locale, and a choice example.
Andradite var Demantoid
Tubussis Farm 22, Daures
6.2 x 5.4 x 4.2 CM (cabinet)
A fine cluster of stacked Demantoid Garnets that contrasts well with the matrix. Excellent color and luster, the main Garnets are 2.6 CM tall and in fine condition. No damage seen even under high magnification. The matrix is a mix of Quartz, Calcite and Prehnite, this holds several smaller Andradites as well. These were big mineral news a few years ago when they were more available, these are now quite scarce.
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.
Epidote -vintage, classic Swiss
5.4 x .3 x .3 CM (small cabinet/ large miniature)
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.
