Spangolite with Connellite
stock #18.1-508
La Finosa Mine, Fontana Rossa, Ghisoni Corte, Haute Corse
Corsica, France
6.2 x 4.8 x 1.7 CM (cabinet)
price: $240
Dec 2018

A nicely crystallized specimen from this less well known old mine in Corsica. Specimens of this size are very rare and few have crystals that are visible by naked eye. The crystals here are densely packed, cover a sizable area and are brightly colored. The backside is also mineralized but less richly.
Magnetite -Cubic
stock #18.1-262
ZCA Mine number 4, Balmat, Balmat-Edwards District, St. Lawrence, Co.
New York, United States
3.9 x 3 x 2.2 CM (miniature)
price: $380
Dec 2018

Ex. New York State Museum collection specimen with especially sharp, fine crystals. The cubic habit Magnetites from Balmat are renowned as unique in the mineral world. This is a superb specimen with sharp, complete and lustrous crystals. Very few of these are in such clean condition and the form of this is especially distinct. Most cubes show the stepped cubic striations and growth hillocks clearly.
Smithsonite with Mimetite
stock #16.1-672
Tsumeb
Otjikoto Region, Namibia
5.2 x 3.2 x 3 CM (small cabinet/ large miniature)
price: $360
Dec 2018

Cuprian Smithsonite from Tusmeb fills an open seam on the matrix and has partly covered several golden Mimetite crystals. In fine condition, ex. Loben collection (with label) collected in 1986, close to the end of the Tsumeb era. The Mimetites are the slender pointed type and the overgrowth of the Smithsonite crystals is like a cloak. Great luster and excellent condition, the paragenesis is especially clear on this specimen.
Posnjakite
stock #18.1-511
Spania Dolina, Banska Bystrica County
Banska Bystrica Region, Slovakia
6.2 x 3.9 x 3.1 CM (small cabinet/ large miniature)
price: $140
Dec 2018

A fairly dense deep blue color mass of crystalized Posnjakite from Spania Dolina. This ancient Copper mine has been worked for over 1000 years and probably even in the Neolithic era. At times known as Herrungrund (German periods often seen on old labels). This deposit is very large and has many old mines along a belt of several kilometers. This zone has produced a number of colorful Copper species along the oxidized zone of the deposit. Thgis is a choice specimen for the area.
Rhodochrosite with Quartz- Classic
stock #18AX-10-076
American Tunnel Mine, Silverton, San Juan Co.
Colorado, United States
7.4 x 5.1 x 3.1 CM (cabinet)
price: $475
Dec 2018

Well defined and sharp rhombs of Rhodochrosite from the classic Colorado locale of the American Tunnel in Silverton. This is the "other" Colorado Rhodo locality that was world famed long before the great finds at Sweet Home. The Am Tunnel Rhodos are also not in the same high price bracket as Sweet Home, but can be quite choice. The locality had a long history of producing Rhodochrosite specimens usually a more pale pink or less well formed. This is a unusually attractive specimen with sharp red crystals that are well exposed and esthetic. Three dimensional, undamaged and far better than usual with a contrasting matrix. Ex collection of R and A Palmer, W Hladysz and A Dilldallion.
Descloizite
stock #18.1-310
Berg Aukus, Grootfontein District
Otjikoto Region, Namibia
8.3 x 6 x 4.1 CM (cabinet)
price: $1950
Dec 2018

A superb cabinet specimen of Descloizite crystals in two generations. The larger more recent Descloizite rests on a druze of earlier small orange and red crystals. The larger crystals are arranged in fans, stacks and bundles in extraordinary forms. No damage, sharp and very three dimensional. The worlds best Descloisites all came from Berg Aukus, and these were in many exotic habits and complex twins. The mine is gone and there will be no more, good specimens have become highly desirable and scarce. This specimen is certainly top quality for the specie and locale with very unusual structures. Far better in person, a killer display and the crystalography is amazing.
Vesuvianite
stock #18.AX-509
Sierra de la Cruz, Municipio de Sierra Mojada
Coahuila, Mexico
7.3 x 6 x 3.7 CM (cabinet)
price: $80
Dec 2018

Blocky habit Vesuvianite crystals that are doubly terminated are studding a contrasting Rhyolite matrix. From very old finds at the locality once called Lago de Jaco, now Sierra de la Cruz. The Vesuvianites are well exposed from the matrix and are nearly all bi color. This habit of Vesuvianite was collected before 1980, there have been no more in recent years.
Enstatite (doubly terminated) on Almandine
stock #18.1-507
Barton Garnet mine, Gore Mountain, North River
New York, United States
2.4 x 1.6 x 1.2 CM (thumbnail)
price: $300
Dec 2018

A rare doubly terminated, complete enstatite (Hypersthene) crystal 2 CM long on bright red Alamandine. From the famed Gore Mt Garnet locality that produced huge masses of Almandine years ago. Hypersthene was also fairly common but mostly massive or very poorly formed. This Enstatite is crude but with clear form with a melted edge look. The crystal is perfect, undamaged and nicely perched on the Garnet matrix, this is not typically a pretty mineral but this crystal has charm. This is the best formed and most distinct Enstatite I have seen from the locale, a fine thumbnail for the region.
