4.9 x 4.2 x 2.3 cm. A rich, attractive copper specimen from the New Cornelia Pit, making for a fine, hefty miniature for this locality. Ex. Harold Urish Collection.
7.9 x 4.8 x 4.8 cm. An old-time, classic copper in calcite specimen from Michigan. The curved vug if filled with glassy and lustrous, copper in scalenohedral calcite crystals to 1.1 cm. Certainly around 100 years old. Ex. Jaime Bird Collection.
A substantial (not wimpy and thin, but heavy in the hand) specimen of penny-bright copper from Arizona, nice from both sides. 10.5 x 5.5 x 0.4 cm
A fine copper specimen from Russia, crystallized from top to bottom in the feathery herringbone style. 3.5 x 1.3 x 0.1 cm
A penny-bright specimen of copper from Arizona, with a delicate, leafy form - displayable from either side. It is not wimpy and thin (easily bendable), but is actually more substantial than it looks. 12 x 5.9 x 0.2 cm
A fine, herringbone-style "feather" of copper, crystallized from top to bottom, from the finds of world-class copper specimens in one pocket here about a year ago 4 x 1.5 x 0.1 cm
15.6 x 7.2 x 5.4 cm. A unique, sculptural, large cabinet copper specimen from the mines at Bisbee. This copper specimen looks like a pointed trowel or carpenter’s plane with a handle. Cuprite causes the intense, rust-red color. The bottom of the "trowel" and the underside of the "handle" have striking, arborescent copper growth patterns. This is old material from Bisbee. Ex. Mullane Collection.
6.0 x 2.8 x 1.7 cm. A beautiful, very dense "feather" of spinel-twinned, flattened crystals and hoppered cubes of copper crystals from the famous 1970s finds at the Ray Mine. The copper in this very sculptural piece has a gorgeous patina. Copper cubes are rare in nature and very uncommon from Ray. Ex. Jaime Bird Collection.
3.7 x 3.5 x 2.6 cm and 3.8 x 3.4 x 2.7 cm. Here is a fine thumbnail set consisting of a crystal of Aragonite and a pseudomorph of Copper after Aragonite from the locality of Corocoro. These floater specimens are well known from Bolivia for their great form and color, and this set is fine illustration of the "before and after" effect which is rare to find for most pseudomorphs, especially from the same locality. There hasn't been any significant amount of these specimens on the market in approximately 25 years, and they are often only found in old collections.
3.0 x 1.0 x 1.0 cm. An elegant, folded, leaf-like, spinel-twinned copper crystal from the famous 1970s finds at the Ray Mine of Arizona. This classic form has an interesting "stem", a beautiful, coppery patina and looks good from all sides. This piece was not treated in any way to enhance shine. It’s completely natural. Ex. Jaime Bird Collection.
23.0 x 14.6 x 9.7 cm. An amazing, large cabinet copper specimen from the White Pine Mine of Michigan’s Copper Country. This incredibly sculptural sheet of folded natural copper looks like an owl with partially folded wings perched on a ship-like slab of matrix Shale. The copper sheet has a super patina and the bit of embedded shale on the "wings" is a nice accent.
Larger and more substantial than the thumbnails we have been leaking out to the auctions, this is a SUPERB mini. A well-crystallized lower portion serves as an attractive “base”, and is connected by a stalk to an upper branch rich with spinel-twinned crystals – very sculptural and fine! 4.3 x 2.5 x 1.1 cm
10.7 x 4.0 x 1.2 cm. A fine and rich specimen of bright, micro-dendritic copper in a sawed, transparent cabinet gypsum cleavage from the Mission Mine of Arizona. Old material. Ex. Mullane Collection.
2.4 x 2.1 x 2.0 cm and 2.5 x 2.2 x 2.1 cm. Here is a fine thumbnail set consisting of a crystal of Aragonite and a pseudomorph of Copper after Aragonite from the locality of Corocoro. These floater specimens are well known from Bolivia for their great form and color, and this set is great way to illustrate the "before and after" effect which is rare to find for most pseudomorphs, especially from the same locality. There hasn't been any significant amount of these specimens on the market in approximately 25 years, and they are often only found in old collections.
A very rich Michigan specimen of native copper crystals in matrix, with an unusual habit. The nicely tarnished copper crystals are radiating masses of flattened spinel-twinned crystals. The specimen has the shape of South America or Africa, depending on which side you look at. 5.7 x 4.9 x 2.8 cm
