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.
A fine Tsumeb Smithsonite that is a very rare blue to deep blue green color. The Smithsonite also has some small Calcite crystals on some surfaces that are colored reddish from Hematite. The outer edges show some very minor chipping but the entire display surface is in pristine condition, very lustrous and undamaged. I have only seen a very few specimens of this color an they were thumbnail sized. The specimen is double sided but the back is a red-brown color botryoidal smithsonite that is far less attractive than the front side. A very nice esthetic specimen with great color but an especially great addition for a Smithsonite suite or Tsumeb collection
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.
