A rather hefty small cab of copper from Michigan, with a well-formed 1 cm crystal at one end; and a pretty antique patina. Super piece for this mine! 6.8 x 3.9 x 2.7 cm
An aesthetic toenail specimen of crossed, spinel-twinned copper crystals with nice patina from a lesser-known Zambian copper mine, the Mufulira. The large crystal really looks like a spear point. These came out in the 1960s. 2.8 x 1.8 x 0.9 cm
A pristine, excellent and floater specimen of rosettes of copper pseudomorphs after azurite crystals from the famous Georgetown District of New Mexico. This is one of the best copper pseudos, that we have offered at auction. Ex Richard Hauck Collection. 3.2 x 2.8 x 1.9 cm
A showy and excellent branching thumbnail of lustrous, spinel-twinned silver crystals with quartz and copper from the famous Keweenaw Peninsula of Michigan. Ex Richard Hauck Collection. 2.5 x 2.3 x 0.8 cm
Atop a translucent partial calcite crystal sits a knob of calcite inside which you can see a rich inclusion of penny-bright copper. This is an old Michigan specimen. 6.0 x 5.5 x 4.4cm
An UNUSUALLY SCULPTURAL, old-time Michigan piece of flattened, tarnished silver on massive copper in conglomerate from one of the conglomerate lodes of the famous Keweenaw Peninsula. Ex Richard Hauck Collection. 5.5 x 4.9 x 4.2 cm
A SUPERB, old-time, complete undamaged CABINET FLOATER of arborescent, spinel-twinned copper crystals from the famous Houghton area of the Keweenaw Peninsula. It is 3-dimensional, LARGE, and extremely intricate yet not so delicate you cannot handle it. The piece was formerly in the collection of Peter Zodac, founder and first publisher of Rocks & Minerals magazine. Ex. Richard Hauck Collection. 10.3 x 5.5 x 3.7 cm
A fine "feather" of copper, crystallized from top to bottom, from the Itauz mine in Russia. The mine is now NOT producing any more copper specimen of this type. It is hoped it will produce again in the future, as the strip mine widens, but there is no assurance of this. And, in any case, the last batch of specimens that came out was more "brushy" in appearance and did not include these superb herringbone-patterned feathers or fine spinel-twinned specimens. 3.1 x 2.3 x 0.3cm
A large specimen of wonderfully crystallized Michigan copper, with a very sculptural form! This piece came out of the collection of Richard Hauck. 13.0 x 7.2 x 1.0cm
White Pine Mine silvers and coppers are of course quite desirable, and this is an elegant floater branch with a nice patina. Better on the vertical for display at home. 9.3 x 1.4 x 0.6 cm
A SUPERB Michigan toenail copper. An aesthetic, arborescent, flattened, vertical fan of hoppered tetragonal copper crystals with an excellent patina rests on a nest of spinel-twinned copper crystals. Hoppered tetragonal copper crystals of this habit and quality from the Copper Country are RARE. The back of the fan consists entirely of flattened, spinel-twinned copper crystals. Ex Sam Nasser Collection. 3.0 x 2.6 x 2.3 cm
A BEAUTIFULLY ARTISTIC sculpture of lustrous, elongated, spinel-twinned copper crystals from the famous White Pine Mine of Michigan. About as good as it gets from the White Pine Mine, which closed in 1995. Ex Marty Lewadny Collection 4.2 x 3.2 x 1.5 cm
A lustrous, 1.5 cm silver crystal with rounded edges aesthetically perched on quartz-rich matrix with a band of dendritic copper crystals from Houghton County, Michigan. A classic, old-time Copper Country piece. 2.7 x 2.1 x 1.5 cm
An AESTHETIC, arboescent cluster of spinel-twinned copper crystals with a nice patina from the famed and long-closed Champion Mine of Michigan. 3.2 x 1.3 x 1.0 cm
The recent discovery(3 years ago) of copper specimens from this deposit garnered a lot of interest from collectors. What makes this specimen so great is that it is composed of featherlike, interlocking groups of spinel twinned crystals; along with a wonderful patina and impressive herringbone pattern. This is a VERY choice miniature! 4.2 x 3 x 0.5cm
