4.8 x 3.7 x 3.0 cm. A major Bisbee cuprite miniature, with sharp crystals stacked in a very hefty mound on minimal matrix. Bisbee crystallized cuprites tend not to be so rich and concentrated, and this is. I have not cleaned it with metal cleaners to strip away the old patina, but it is probably red underneath its oxidation coating. Ex. Harold Urish Collection.
6.4 x 3.4 x 2.4 cm. Here we have briliant fiery-orange-red calcite crystals colored so nicely by inclusions of the cuprite varietal chalcotrichite. As a bonus, there are small bits of native copper wires growing about the base of the calcites as well, so you can see a very interesting assemblage in one spot. Old material, rarely seen today. Ex. Harold Urish Collection.
7.6 x 5.0 x 3.3 cm. interesting clusters of tiny, sharp, battleship-gray galena octahedrons are attractively scattered on both sides of the vuggy, sculptural matrix of solid cuprite on this excellent old-time specimen from the Dennis Mullane Bisbee Collection. The white areas on the photo are actually powder-blue chrysocolla, a colorful accent.
13.8 x 12.4 x 3.5 cm. The Pearl Handle Pit of the Ray Mine is one of the more noted localities in the southwestern United States for crystallized copper. This very fine, two-sided, cabinet plate is composed entirely of sharp tetrahexahedral copper crystals with a rich patina and a bit of embedded, breccia matrix. Scattered on both sides and particularly along the crest of this specimen are beautiful, gemmy, cherry-red cuprite cubes to 4 mm. An excellent, large copper with cuprite specimen from this famous locale. Comes with two, older labels and the former dealer label indicates that the piece was collected in the 1960s.
4.2 x 2.9 x 2.6 cm. Lustrous, sharp, wine-red cuprite crystals in clusters or as discrete crystals are nicely scattered on the 3-dimensional sliver of gossan matrix. Beautifully complimenting the cuprites is a rich carpet of sparkly, pastel-green cuprian calcite microcrystals and a few yellow willemite crystals. Excellent combination material from the Tsumeb Mine and the Rob Smith Collection.
6.4 x 6.4 x 0.3 cm. A very strange, natural copper disk from the Itauz Mine of Kazakhstan. I have never seen one like it from this locale. The disk has a coating of red cuprite and also has a nice patina. Unusual material from this well-known locale.
1.4 x 1.0 x 1.0 cm. A sharp, pristine, floater cuprite crystal with textbook octahedral crystal form beautifully coated with malachite from Chessy, France. The crystal faces are strongly recessed or hoppered, giving a dramatic effect. The ancient Chessy mines were closed by the end of the 19th century and this is an outstanding example of a classic form and species. Ex. Dick Jones Thumbnail Collection.
2 x 1.7 x 1.4 cm. A magnificent group of stacked Cuprite octahedrons, the largest of which is .7cm on edge. The luster is a beautiful, brushed metallic silver, and the modified edges of the crystals add even more drama to the piece. Naturally, there is some contacting along the back, but it is insignificant. These Cuprites look gorgeous as they glow red with transmitted light. Ex. Wendell E. Wilson Collection.
4.2 x 3.9 x 1.0 cm. An amazingly sculptural copper with cuprite specimen from the Ray Mine. This piece looks just like a poodle with a turned head. The ears, long neck, legs, body and tail are very evident. Very sharp spinel-twins and tetrahexahedral copper crystals with a sparkly, cuprite over-coated patina comprise this very interesting piece. This superb piece comes from a recently uncovered stash from the well-known copper mine, as the specimens were collected in 1959.
6.1 x 5.8 x 3.7 cm. A sculptural, latticework and box-work of sharp, wine-red cuprite crystals and rust-red cuprite crust coating tetrahexahedral copper crystals with a bit of attached matrix from Arizona. Classic Ray Mine material. This fine piece has a distinctly biomorphic-look, like a dog’s head and body. Old-time material from the Robert Sullivan Collection.
4.5 x 4.2 x 0.8 cm. An amazingly sculptural copper with cuprite specimen from the Ray Mine. The spinel-twinned portion at the right is 3.2 cm. Very sharp spinel-twins and tetrahexahedral copper crystals with a sparkly cuprite, overcoated patina comprise this very interesting piece. This piece comes from a recently uncovered stash from the well-known copper mine, as the specimens were collected in 1959.
5.3 x 4.0 x 0.9 cm. An amazingly sculptural copper with cuprite specimen from the Ray Mine. Bright red, hair-like crystals of cuprite variety chalcotrichite are also evident on this piece. Chalcotrichite is uncommon for this lot and is a real bonus. This specimen looks distinctively biomorphic, like a kneeling Scottish terrier with tufted ears and nose. Sharp spinel-twins and tetrahexahedral copper crystals with a sparkly, cuprite over-coated patina comprise this very interesting piece. This super piece comes from a recently uncovered stash from the well-known copper mine, as the specimens were collected in 1959.
2.2 x 1.6 x 1.6 cm. A superb modified, octahedral cuprite crystal from the Emke Mine at Onganja, Namibia. This crystal has been etched out from under a coating of malachite, as a bit of malachite remains and the cuprite faces are pitted. The surfaces retain excellent lustre. This crystal is complete-all-around and is pristine. Outstanding classic material from the 1970s. Ex. Carlton Davis Thumbnail Collection.
1.7 x 1.4 x 1.3 cm. Shattuckite is normally found as crusts or small acicular radiating sprays. I hear that once, in the early 1980s, they found a pocket of these amazing pseudomorphs after cuprite. I have seen 3 of them in my lifetime, only. This is the largest and sharpest by far of those. To find such a large shattuckite in the form of a pseudomorph, or in any form for that matter, is truly extraordinary. The waxy-lustre and the strong blue color are very attractive, and the well-terminated faces show nicely in front (though there are a few rougher faces in back). Really quite a remarkable specimen. Ex. Wendell E. Wilson Collection.
6.5 x 4.4 x 4.2 cm. Sharp, sparkly, octahedral, wine-red cuprite microcrystals richly invest all sides of the very vuggy, sturdy gossan matrix on this fine and very rich copper ore specimen from the famous Czar Shaft at Bisbee. This noted mine closed in 1944, so this is obviously old-time material from this famous locale. Ex. O.D. Brown and Dennis Mullane Collections.
