Chalcotrichite with Copper
Bisbee, Warren District, Mule Mts., Cochise Co.
4.3 x 4.2 x2.4 CM (miniature)
Old Bisbee specimen has three vugs with Cuprite V. Chalcotrichite crystals with typical bright red color. Ex. Rocksmith specimen, there are a few tiny bits of Native copper and some calcite crystals that seem to have copper inclusions too. Classic material, this small piece is relatively affordable for one of these.
Grossular on Diopside
Jeffrey Mine, Asbestos
6.8 x 4.7 x 2.1 CM (cabinet)
Gemmy, sharp and colorful, these garnets are a bright tangerine to pinkish in hue. These contrast with the green Diopside crystals that cover the display face. The main crystals are in perfect condition, there is some minor damage at the outside edges. Displays very well, these Jeffrey specimens are modern classics. The mine is closed forever but these specimens are now prized as some of the best ever found.
Stunning red Rubellite crystals with delicate "castellated" hollow terminations perched on a flower-like rosette of Cleavelandite. Great form, color and display quality this rare etched habit of Elbaite is from a small recent find. In incredible condition, undamaged despite the delicate structure and attractive from all angles. Better in person, the larger Tourmaline is 4 cm tall, the smaller one is extra gemmy and perfectly hollowed out. An great value for a rare and pretty gem crystal specimen.
A sculptural specimen with a sharp distinct main dodecahedral crystal perched on a Copper stalk. Esthetic and choice old piece that oddly looks like a goose from some angles. Ex. Warren Johannsen collection likely pre 1940 vintage.
Choice, bright blue transparent to translucent Willemite clusters covering matrix. Several have well-formed crystals in stacks and isolated prisms. Some areas of Duftite provides a nice contrast. Excellent "wet look" luster, this is in fine condition.
A classic form for Chrysoberyl showing an inverted V twin well-exposed on matrix. From the finds in the 90's at Colatina, this is a sharp crystal in fine condition. Hard to find any of quality on the market now, this has textbook form. Perfect by naked eye, some micro contacting (mostly on the back side) is evident with magnification.
A fine Tsumeb specimen with sharp, clear Calcites growing on a bright contrasting green Duftite. The Duftite can be seen through the Calcites and the condition is excellent. The underlying matrix is a thin section of Dolomite cast which is itself a very interesting and quite desirable collectable. First rate esthetics.
Casapalca Mine, Casapalca, Huarochiri Province
4.3 x 3.3 x 1.9 CM (miniature)
A cluster of Tetrahedrite crystals showing classic forms and with fine patina. From the famed Casapalca mine, this has sharp form with crystals penetrating each other at all angles. Minimal chipping is noted on on some outer edges, most crystals are complete and undamaged.
