A lovely, branching, crystallized copper from Russia, with a fine patina. The Itauz is not producing anymore of this style, sadly, because for awhile there it was producing the finest copper specimens around. These are just so sculptural! 6.0 x 3.1 x 0.7cm
A SUPERB and AESTHETIC, spinel-twinned copper crystal with outstanding patina from the famous New Cornelia Mine at Ajo, Arizona. Ex Norm Dawson Collection. Killer miniature! 4.5 x 1.2 x 1.2 cm
The Onganja is known for fine crystallized coppers, but not so much for nice copper/calcite combos (as Michigan is). But here you have a really unique piece, with nice branches of crystallized copper and a gemmy calcite crystal that has copper penetrating inside it! Very unusual! 6 x 4.8 x 3.4 cm
A magnificent, very arboreal-looking cluster of THICK copper crystals, forming a solid tree rising from the quartz matrix. This is a dramatic and exceptional piece with a lot of character, and is MUCH MUCH better in person than it appears. It came to me in trade with Gene Meieran, in whose collection it resided after he made a trade with the Seaman Museum. Courtesy of curator George Robinson, I can say that the piece came to the museum "some time after 1917." Hubbard died in 1933. There's general information on Hubbard given in the MR "copper country" issue in the section at the end on the Museum's various collections. 10 x 7.5 x 4.5 cm
WOW! Silver CRYSTALS to over 1 cm are here perched in a protected cavity of a HUGE, if somewhat lumpy and rounded, copper crystal! The association is really pretty impressive, and it is much better in person. The bright contrast makes it stand out from most silver/copper combos and there is no intermixing of the two elements as is more common. 6.9 x 4.6 x 3.1 cm
A remarkable locality piece - BUTTE coppers are VERY scarce. This is a legitimate specimen with documentation that it was collected by a prominent Butte collector in teh 1960s. I obtained it in trade from another prominent Butte collector, and he provided a label and the story. It ain't pretty, but it IS significant for this important mine! 4.6 x 1.9 x 1.6 cm
A showy and excellent specimen of arborescent, spinel-twinned copper crystals with scatterd, platy copper crystals from the famous Emke Mine at Onganja, Namibia. 3.9 x 2.5 x 1.2 cm
A classic, sliced ore specimen of a vein of massive, brass-colored domeykite in quartz with copper. Domeykite is a copper arsenide and this is a fine, rich representative piece from the famous Mohawk Mine of Michigan. Ex Richard Hauck Collection. This small cabinet weighs over 1 and 1/2 pounds or 688 grams! 6.7 x 6.4 x 4.0 cm
A unique combo specimen from Onganja featuring embedded microcrystals of the copper mineral chalcotrichite, with deep red color, that have formed on a stalk of natural copper. 5.3 x 2.2 x 0.7cm
14.6 x 9.6 x 1.8 cm. A gorgeous old Russian copper specimen, distinguished not only by its size and graceful form, but also by color accents from malachite(the green) and cuprite (the reddish tones in the copper) where these minerals partially replaced the copper. Check out the locality: this is not a specimen you see around on the market; it came to us from a Russian scientist, who verified the cuprite and malachite replacement. Said to be 20 years or so old, having been collected at the end of the 1980s.
Matrix coppers from the Itauz are rather rare, and this is a such a one, with the native copper having grown against a natural "base" of matrix. This is the brushy form of specimen that came out in the last year of production before the pit mine moved past the specimen-producing area - and it will be years before they are back around that part , if at all , from what we hear. 4.1 x 2.2 x 2.1cm
A sculptural and elegant copper from a classic old Michigan mine! A long, slender, arrow-like stalk with a branch coming off the side of it. Fine, penny-bright patina on both sides. Came out of the Richard Hauck collection. 15.2 x 10.0 x 0.6cm
Talk about a piece of history: a copper-mineral specimen from the old mining and shoot-em-up western frontier town of Tombstone, Wyatt Earp''s stomping ground! This is a specimen of fibrous malachite and native copper, out of the Richard Hauck Collection. with label 6.3 x 5.4 x 3.7cm
A specimen from the wonderful finds of crystallized copper in Russia over the past few years, this one with a strange and pretty patina that combines a silvery tone (cuprite?) with rust tones from iron inclusions. Pretty branching form. 5.2 x 4.3 x 0.4cm
A HUGE, PENNY-BRIGHT, SCULPTURAL specimen of natural native copper from Arizona! It shows fine branching structure. The specimen is not thin and flimsy, either - it is rather substantial and in fact is hard to bend with the hand. A big, showy copper specimen! 25.8 x 18.2 x 3.9cm
