Cuprite (with native copper

Wheal Gorland
Cornwall, England
7 x 5.6 CM (cabinet)
price: $125


Sparkly bright red cuprites on matrix with some native copper in classic form from a Cornwall classic locality. A lot of Cuprite here, some in crystals reaching 5 mm. Some damge is found with 10x magnification but many of the crystals are perfect and have very good color.
Quartz (Herkimer diamond) with prismatic voids
stock #7 NY-042
Ace of Diamonds mine, Herkimer
New York, United States
8.5X5.2 CM (cabinet)
price: $250


A sizable, sharp and glassy pair of intergrown Herks that have far better than average clarity. These have some fine bubbles. anthraxolite flakes and tubes included within, but the best is the rare "crystal voids" that are cavities shaped exactly like a small doubly terminated quartz. Contacted on the rear and with a few chips but still displays well and the inclusions are easy to view.

stock #AC-095
Montaju Mine, Traversella, Chiusella Valley, Canavese District, Torino
Piedmont, Italy
5.4 x 3.3 CM (miniature)

A bright and well crystalized garnet plate with many translucent dark orange - yellow crystals up to .7 CM covering the surface. In good conditiion overall but with some contacted and damaged crystals as seen in the photos.
Hausmannite pseudo after Manganite
stock #8.1-224
Ilfeld, Nordhausen, Harz Mts
Thuringia, Germany
7 x 5.2 CM (cabinet)
price: $500


A remarkable piece from the legendary classic Manganite locality of Ilfeld, this piece has many fine, large crystals to 3.4 CM in size standing out from the matrix and showing the Manganite form perfectly. Collected from a rediscovered 15th century dump and adit area in 2006, the site is now closed and only a small number of specimens were recovered. A fantastic Psuedomorph, a fine Ilfeld piece and a great bit of mineral history, this is a "black rock" with a lot of class and form!

Commodore#5 Mine, Amethyst Vein, Creede District, Mineral County
Colorado, United States
8 x 6 CM (cabinet)

Very attractive, classic Colorado association with the main Sphalerite crystal of 2.9 CM size on a contrasting purple matrix. No damage, displays nicely, and the Sphalerites are translucent under strong light and are a deep yellow color.

Resuperferolitica Mine,Santa Eufemia
Cordoba, Andalucia, Spain
8 x 6 CM (cabinet)

Ex. John Marshall collection, a very well crystalized Santa Eufemia Pyro with large individual crystals that exceed 1.6 CM. This is overall in excellent condition and is crystallized on 2 sides with large vugs filled with sprays and freestanding individual crystals. A super display peice from a very important locality.
Vanadinite (arsenian Vanadinite- Endlichite)
stock #AC- 133
Near Bannock (Bannack) City, Beaverhead County
MONTANA, United States
9 x 7.2 CM (cabinet)
price: $400


A fine locality specimen with a great history as well. This comes with a old Shortmann label with the old address, and stamped on the back "from the 1947 sale at Hotel Lexington, NYC". These sales were done in conjunction with Arthur Montgomery and are often credited as being the first mineral shows in the USA. The Bannock or Bannack city locality was already long finished as a mine by the time of the sale (it was a ghost town). The mines were begun in 1863 and were noted as a source of auriferous Pyrite and Galena. Few specimens of any minerals survive in collections from this important district, and while there are examples of several lead, silver and gold minerals noted, this is the only Vanadinite I can find a record of. It is sizable, distinctive, attractive, well crystalized, undamaged and frankly important as a locality specimen.
Celestite (Barian Celestine)
stock #AC 313
Girgenti
Sicily, Italy
9.7 x 7.2 CM (cabinet)
price: $325


A beautiful glassy spray of powder blue crystals radiating upward from a massive base. This is a very old specimen from the classic Sulfur locality that has been mined for many centuries. This type of celestite with the blue color has sometimes been labeled as Barite but often on analysis is found to be Celestite with some Barium, The piece is attractive despite chips and damage to a few crystals. Very uncommon to find material this attractive on the market, the blue color is especially desirable.
