7.7 x 4.3 x 0.5 cm. A SIMPLY ELEGANT, arborescent latticework of spinel-twinned copper crystals from the 2006 finds at the Itauz Mine of Kazakhstan. The cuprite coating adds beautifully to this artistic piece. Ex. Karl Warning Collection.
12.4 x 8.1 x 2.5 cm. This is an extremely hard to find specimen from maybe THE classic American locality: Bisbee, Arizona. It is a rich layer or mat of the rare copper oxide chalcotrichite (in Greek it means "hairy copper", which is a very good description). It consists of tiny acicular (hair-like) crystals - in this case in a layer exposed on the matrix.
8.0 x 3.5 x 2.1 cm. A very uncommon specimen of chalcotrichite as red INCLUSIONS in crystals of calcite - with the added bonus of a finger of crystallized copper on the specimen to make it a wonderful copper-mineral combo specimen. What you mostly see from this mine are specimens of copper alone. This rare combo piece came out of the collection of noted African mineral collector Marshall Sussman. It is a superb association piece and something you do not see from anywhere else I can think of but old Bisbee.
6.5 x 4.4 x 3.7 cm. An OUTSTANDING example of a RARE occurrence, specimen-grade cuprite crystals from the famous Chuquicamata Mine of Chile. And this showy piece is RICHLY covered with lustrous, deep wine-red crystals to 8 mm. Nearly all of the major cuprites are pristine, excepting the bit of periphery bruising to the large crystal. This is an EXCELLENT cuprite specimen from this very well-known locale for very rare copper minerals like natrochalcite and krohnkite but I have only once before seen a CUPRITE from here. For some reason, the simple copper minerals and copper itself just didn’t really stay around in this deposit, and altered away. Thus this is an important and educational addition to any Chuqui suite. Ex. W. Schultz Collection.
2.2 x 1.3 x 1.0 cm. Brilliant fiery-orange calcites, made so by microscopic inclusions of the cuprite varietal chalcotrichite. Small piece, but a splashy one nonetheless, and a choice and unusual piece for any thumbnail collection. Ex. Charlie Key Collection.
4.7 x 4.3 x 2.8 cm. Lustrous, discrete, wine-red cuprite crystals to 6 mm aesthetically scattered on matrix covered by sparklly delafossite microcrystals from recent finds at the well-known Chengmenshan Copper Mine of Jiangxi Province. Excellent and showy material.
7.2 x 4.7 x 3.1 cm. A UNIQUE and UNUSUALLY SHAPED Tusmeb specimen of reniform, botryoidal, green to grayish mottramite, This piece is very heavy for its size, because the banded mottramite is cored with massive cuprite. 162 grams. The end and base reveal the banding and cuprite core. Showy in its own way. Ex. Rob Smith Collection, a noted Tsumeb collector.
1.7 x 1.1 x 0.6 cm. A showy and excellent thumbnail of lustrous, stacked, pastel-green to blue plancheite pseudomorphing sharp cuprite crystals from the less well-known M’sesa deposit of Zaire. This open-pit mine closed in the 1970s, so this is old and choice material, seldom available. Ex. Dick Jones Collection.
This is a very intricate combinaiton piece featuring rich drapery of bushlike copper crystals, with a nice reddish patina, overtopping GEMMY, brilliantly lustrous rhombohedral clacites that are colored by red chalcotrichite inclusions; and the calcite itself grows over brilliantly lustrous small quartzes with hematite or iron red inclusions. All are classic for this locality, but I cannot recall seeing it all together in one specimen like this! 8 x 7 x 4 cm
9.8 x 6.8 x 0.6 cm. An AESTHETIC latticework of stout, cuprite-coated copper crystals from the famous Phoenix Mine of Michigan. This is an outstanding, OLD-TIME, Copper Country specimen. The pleasing red color enhances the multitude of copper crystal forms, which includes some very long spinel-twins, along with delicate-looking, arborescent tetrahexahedral crystals. A very showy two-sided specimen.
2.8 x 2.2 x 2.0 cm. An OLD-TIME, CLASSIC and showy specimen of lustrous, deep wine-red cuprite octohedrons nicely complimented by a bit of malachite from the Ural Mountains of Russia. These deposits are LONG extinct. Ex. Ferguson Collection, circa 1800 and Sam Nasser Collection.
9.9 x 4.0 x 3.5 cm. A STRIKING, elongated Tsumeb combination specimen of amorphous, orange-red cuprite variety chalcotrichite RICHLY covering a vug lined with grayish-white dolomite. A REALLY EXCELLENT and UNCOMMON specimen from this famous and now-closed mine. Ex. Harvard and George Elling Collections.
7.5 x 6.5 x 5.0 cm. A striking, 3.6 cm vug filled with scintillating, magenta, hair-like needles of cuprite variety chalcotrichite in massive hematite matrix from the recent finds at the famous Daye Mine of China. This is a rich and very fine, highly representative specimen of the species and locality.
2.6 x 2.2 x 2.2 cm. A pristine, sharp, GEM, octahedral cuprite crystal aesthetically covered by malachite. This is CLASSIC, highly desirable material from the famous Emke Mine at Onganja, Namibia. These came out in the early 1970s, with no more since. The UNRETOUCHED backlit photo highlights the gemminess and intense, blood-red color saturation. Ex. Smale Collection.
2.5 x 1.5 x 1.4 cm. An old-timer for sure, these crystals of cuprite have long lost their red color, but their crystal form persists. From the collection of James E. Moresby White. Ex. Carnegie Museum Collection.
