An excellent and very sculpturally-shaped cluster of elongated tetrahexahedron copper crystals with EXCELLENT cuprite and tenorite patinas from the recent finds at the Old Indiana Mine in Ontonagon County, Michigan. Dramatic, 3-dimensional, and better in person! 7.2 x 5.5 x 3.7 cm
7.7 x 5.5 x 4.7 cm. A 2.5 x 2.0 cm, artistic "shrub" of arborescent, spinel-twinned copper crystals is perched on a solid matrix of crudely crystallized to hackly copper pseudomorphs after cuprite crystals. Old-time material from Bisbee and the Mullane Collection. Very rich copper ore. Weighs 251 grams.
3.9 x 2.9 x 1.9 cm. A very fine, sculptural copper specimen consisting of very sharp tetrahexahedrons and spinel-twins from the famous mines at Bisbee. The crystals have a pretty patina, as many crystals have a cuprite coating. Every turn presents a different fascinating perspective to this interesting floater. Ex. Dennis Mullane Bisbee Collection.
10.0 x 7.8 x 3.4 cm. A striking and most unusual looking cabinet specimen from the Geevor Mine of Cornwall. Sharp copper microcrystals fully surround large brecciated quartz fragments on both sides of the scuptural specimen. Cuprite richly coats much of the copper and adds a very nice patina. The large breccia fragment is 5.3 cm across. The area around this historic mine was intermittently active from the late 1700s until 1990. Ex. Wes Parker Collection.
5.0 x 3.0 x 3.0 cm. A fine combination specimen from the Tsumeb Mine. A 9 mm, lustrous, translucent, stair-stepped, wine-red cuprite crystal is aesthetically set in a vug lined with lustrous, snow-white smithsonite rhombs and beautifully accented with contrasting, green, primary malachite blades. Classic and beautiful combination material from the Wes Parker Collection.
Richly covered, lustrous blood-red needles of chalcotrichite or "hairy copper" encrust matrix from the Cole Shaft of the Copper Queen Mine at Bisbee. Old and very desirable material from Bisbee, especially since the specific mine shaft, level and stope locality is known, meaning that this was an important specimen when it was collected. Quite the contrast, with the red chalcotrichite next to the yellow iron oxides! 5.5 x 4.5 x 2.6 cm
18.5 x 13.0 x 7.8 cm. Lustrous sprays of pretty green, acicular brochantite crystals cover the large cabinet matrix of solid, massive cuprite on this excellent old-time specimen from the famous mines at Bisbee. The brochantite has a beautiful chatoyant character to it. Ex. Dennis Mullane Bisbee Collection. Very rich copper ore, weighing 7.9 pounds or over 3.5 kilograms.
6.1 x 3.0 x 1.2 cm. A sculptural copper with cuprite specimen from the Ray Mine. This interesting two-sided piece consists of sharp, tetrahexahedral copper microcrystals with a sparkly, cuprite over-coated patina partially covering very sharp, arborescent spinel-twins. This excellent piece comes from a recently uncovered stash from the well-known copper mine, as the specimens were collected in 1959.
8.7 x 6.3 x 3.3 cm. Colored red by cuprite and green by malachite, this aesthetic copper specimen is extremely well crystallized. The largest copper crystal measures 4.0 cm in length. But the highlight of this specimen is the incredible, spear-like crystal, exhibiting elongated, possible tetrahexahedral twinning. This is a fine old Michigan specimen. Ex. Richard Hauck Collection.
7.4 x 3.8 x 2.0 cm. Scintillating, gemmy to opaque, cherry-red, cubic cuprite crystals comprise this striking, two-sided, crust of solid cuprite crystals from the Chino Mine of New Mexico. There are just a couple of small points of attached crust. This was nearly a floater. Outstanding material from this noted locale, and according to the Minette Collection label, was collected calculated 1954. Old-time, superb quality cuprite with textbook crystals and fine color.
4.1 x 2.9 x 0.4 cm. A highly stylized, very aesthetic sculptural copper with cuprite specimen from the Ray Mine. This striking two-sided piece consists of amazing, elongated, arborescent spinel-twins with some sharp, tetrahexahedral copper microcrystals; all over-coated with sparkly cuprite microcystals. This excellent piece comes from a recently uncovered stash from the well-known copper mine, as the specimens were collected in 1959.
7.6 x 7.4 x 1.1 cm. Most people are familiar with the Copper pseudomorphs after Aragonite from this locality, but to find free native Copper is rather rare in my experience. This "sheet" of partially crystallized Copper is a fine specimen from this historic locality. It has a gorgeous blue-green association of Malachite with spots of reddish-black Cuprite and a few areas with bright Copper crystals exposed. These pieces started to trickle out around October of 2007, and this piece is one of the better samples of this material that I have handled.
This is one of the world’s great localities for cuprite, sadly no longer producing. This specimen is covered on the left side by cuprite crystals to .7 cm, but on the right side there is one sharp octahedral crystal measuring over 1 cm. All the cuprite crystals exhibit some lustrous, etched faces. When backlit, they all have bright red highlights. 4.6 x 4.2 x 3 cm
An excellent modified crystal, probably etched out from under a coating of Malachite. The surfaces retain their very good luster and the internal color, as with many fine Cuprites, glows a beautiful cherry red when hit with even moderate light. This crystal is complete almost all around. 2.9 x 2.8 x 2.5 cm
A very showy specimen of etched, red and green cuprite crystals to 5 mm aesthetically perched on the top of light mauve, casted dolomite from Tsumeb. An unusual and uncommon combination. 7.3 x 5.5 x 3.0 cm
