Cuprite and Copper
stock #9.1-030
Bisbee, Warren District, Mule Mts., Cochise Co.
Arizona, United States
6.6 x 4 CM (cabinet)
price: $650


A beautiful, scuptural specimen of well developed Cuprite decorating branching native copper. The Cuprite has excellent fresh red color and shows both single octahedra and flattened elongated octahedra in chains to over 2.5 CM. Individual crystals show bright glassy faces and the whole has a super esthetic form. Bisbee Cuprites are rarely this attractive.
Dioptase with Calcite,Duftite and Arsenotsumebite
stock #9.1-169
Tsumeb
Otjikoto Region, Namibia
4.7 x 3.3 CM (miniature)
price: $250


Brilliant, deep emerald green Dioptase sparkles on a contrasting multicolored matrix. There are several different micro crystals covering the specimen. A very pretty yet affordable miniature from this classic locale. No damage, fantastic color.
Spinel (large twinned crystal)
stock #8 DK-155
Luc Yen
Yen Bai Province, Vietnam
5.1 x 4.2 CM (small cabinet/ large miniature)
price: $680


Sharp. lusterous and with deep purple-red color, this is a fine Spinel with strong form. Gemmy with glass-like surfaces, the transparency is above average for such a large crystal. The faces alternate from a melted or rounded form to sharp prismatic. The crystal shows well "spinel twinning" and is exceptionally sharp for its size. No damage, displays well.
Adamite and Calcite
stock #8 MEX 631
Mina Ojuela, Mapimi
Durango, Mexico
9.4 x 4.4 (cabinet)
price: $250


Unusual and attractive esthetics! A well crystalized Adamite cluster rises from a matrix of gossan that holds a sparkling calcite vug. Good contrast and overall appeal, the color of the Adamite is a rich lemon-green. Some unidentified micro crystals are on the reverse side are a bonus.
Fluorite (Pink- Orange Octahedral) on Muscovite
stock #9.1-166
Chumar Bakhoor, Hunza Valley
Gilgit, Northern Areas, Pakistan
8.4 x 6.7 CM (cabinet)
price: $670


A single modified octahedron (3 CM) of Fluorite set esthetically in a nest of Muscovite blades. The Fluorite has a slight frosting but is very clear internally and the color is especially unusual, being pinkish with an orange hue. At quick glance this can even look like a Scheelite. Overall in good condition, there are some rough areas from muscovite contacts as seen in the photos, they are not distracting. For any Fluorite or Pakistani suite, this is a very desirable addition.
Chalcopyrite (skeletal Crystals) and Enstatite
stock #9.1-165
French Creek Mines, St Peters, Chester Co.
Pennsylvania, United States
4.5 x 3.2 CM (miniature)
price: $350


A delicate and esthetic classic. The early French Creek Chalcos are distinctive and very much sought after, they are definately the most desired US chalcopyrites. The skeletal growth structures make very intricate geometric forms that are well presented here. The enstatite crystals reach 1.6 CM and are all terminated. These make a fine contrast and the overall presentaion is very fine.
Azurite, Malachite w. Minor Cuprite and unknown micro xls.
stock #9.1-164
Cole Shaft, Bisbee, Warren District, Mule Mts, Cochise County
Arizona, United States
8.3 x 5.5 CM (cabinet)
price: $500


A pretty and quite esthetic classic from the John Marshall collection, previously in R. Graeme collection. Labels included list the exact locality as "141 F stope, 1200' (366M) level, Cole shaft." Sharp, undamaged and lusterous blue azurites to 1.3 CM in size scattered in a green vug about 5 CM across. Nice Bisbee material has become very expensive and much less common. A very good value.
Calcite (frosted) on Quartz
stock #9.1-163
Rossie Lead Mine, St. Lawrence Co.
New York, United States
4.8 x 4 CM (miniature)
price: $250


From the classic old locality of Rossie that was active from 1830 to 1860. A nicely frosted main crystal with a few smaller on the sides sits on a quartz matrix. No damage. good clarity and some internal rainbows . This seems to be an untwinned crystal that was less common at Rossie. Calcites from here were used in many crystalographic illustrations and studies in the classic literature. These are rarely available now.
