Smithsonite- classic
stock #17.1-583
Kelly Mine, Magdalena
New Mexico, United States
5.6 x 5.3 x 3.3 CM (cabinet)
price: $475


Kelly Mine Smithsonite with the most desirable wet look luster and good blue color. Ex Hitchings collection this is in fine condition a few of the outer edges show where this was removed but all the display surface is perfect clean and undamaged. A few areas of the white mottling are present which adds a nice contrast. This is a pre 1970 specimen. These have become American classics and there is no other Smithsonite worldwide that has just this look, color and luster.
Autunite
stock #17.1-551
Daybreak Mine, Spokane County
Washington, United States
5.5 x 4.2 x 2.2 CM (cabinet)
price: $475
Dec 2018

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.
Wulfenite with Calcite & Mimetite. - New find
stock #18.1-552
San Carlos Mine, Municipio de Maunuel Benavidas
Chihuahua, Mexico
3.4 x 2.3 x 2 CM (small miniature/ large thumbnail (toenail))
price: $390
Dec 2018

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.
Adularia with Titanite (Classic Alpine)
stock #18.1-441
Rotiaul. Guttannen, Hasli Valley
Bern, Switzerland
7.8 x 4.6 x 4.3 CM (cabinet)
price: $440
Dec 2018

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
stock #18.1-646
Grischun (Grisons)
Graubunden, Switzerland
5.4 x .3 x .3 CM (small cabinet/ large miniature)
price: $360
Dec 2018

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.
Calcite- gemmy, twinned
stock #15.1-513
Elmwood Mine, Carthage
Tennessee, United States
5.4 x 5 x 2.3 CM (cabinet)
price: $360
Dec 2018

Ultra clear, a pair of transparent crystals of twinned Scalenohedral Calcite from the great Elmwood mine. The faces are glassy and the termination tips show a slight hint of a cognac color otherwise these are perfectly colorless. The twinning is both a rotational and interpenetrated type, which is very easy to see in person. Just a hint of matrix is present, mostly on the backside of one crystal. The condition is fine and the terminations are uncleaved, A contact on the back, lower edge is noted but no damage. Now that the Elmwood is closed probably forever, good, clean Calcites of the quality are becoming quite uncommon and prized.
Prehnite -well crystalized
stock #18.1-587
Merelani, Umba Valley, Lelatama Mountains, Arusha Region
Manyara Region, Tanzania
5.7 x 3.9 x 3.2 CM (cabinet)
price: $300
Dec 2018

Radiating cluster of fine terminated Prehnite crystals from the famed Merelani Hills best known for its Tanzanite. In fine condition by naked eye, some very minor bruising is seen with magnification, but overall the visual impression is pristine. This is also a color-changing Prehnite and can look green to a gray-blue depending on the light source. Some of the crystals also show slight rotation or twisting like some of the classic European Alpine specimens.
Beryl var Goshenite- elongated crystals
stock #17.1-537
Hohenstein Massif, Omaruru District
Erongo Region, Namibia
3.6 x 3.1 x 2.9 CM (small miniature/ large thumbnail (toenail))
price: $480
Dec 2018

A superb toenail sized Erongo Goshenite. Perfect colorless Beryl crystals sprout from a Feldspar matrix in an attractive array. Excellent luster, clarity and with a slender habit all the crystals are terminated with the flat top and some tiny pinnacoid faces. An older specimen of a type almost never available. No damage at all, the specimen could be trimmed to a fine competition thumbnail but also looks great as is.
