This is an old Onganja specimen from the old dealer stock of Gary Hansen. You can see sharp faces on the malachite-coated cuprite crystals. The crystals are not complete on the sides, but this allows you to see the glassy interiors of the cuprites (which are actually a very deep red). In addition to these two copper minerals, the Onganja is known for some fine crystallized copper specimens. 4.6 x 3.2 x 2.3 cm
A fine octahedron with modified edges that has excellent luster. Chessy is one of the world’s finest localities for Cuprite, and this is a good example of the species showing alteration to malachite which is classic for the locale. 1 x .9 x .9 cm
A sharp pseudo with very good definition and luster - unusual for the lcoality! 1.1 x .9 x .9 cm
An excellent and aesthetic floater nest of dendritic, spinel-twinned, cuprite-coated copper crystals from a very uncommon Arizona locality, the Old Dominion Mine of Gila County. The cuprite coating adds a beautiful patina to this showy piece. 4.0 x 3.5 x 2.5 cm
A sharp, euhedral and pristine malachite-coated cuprite crystal from the 1970s find at the Emke Mine at Onganja, Namiba. Classic material that is not often available. 2.2 x 1.8 x 1.3 cm
A CLASSIC, solid crust of wine-red, arborescent cuprite crystals from the famous Ray Mine of Arizona. from the Lewadny Collection. 4.0 x 3.0 x 0.7 cm
You have seen the fine crystallized coppers that have until recently been coming from this mine in Russia, but here is a specimen with sharp cuprite crystals (to 0.6 cm) embedded amongst the branches of copper! What is more, the specimen sits on a natural "base" of matrix, very uncommon for these Itauz pieces. A very uncommon and desirable specimen. 5.5 x 4.0 x 2.2cm
A CLASSIC, old-time Cornwall specimen of lustrous, deep red cuprite crystals to 3 mm. This piece is essentially solid cuprite crystals and comes with a British Museum of Natural History label. 5.2 x 4.2 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.
This is an array of crystals to 2 cm, that must have literally taken a lifetime to assemble. These are rare old classics, and you never see many of them around these days, anyhow. This collection includes every shape and form known from the place, from simple octos and dodecs to hoppered crystals that look carved. 2.3 x 2.2 x 2.2 - 0.8 x 0.8 x 0.5 cm
A VERY AESTHETIC, classic, old-time specimen of cuprite-coated, dendritic, spinel-twinned copper crystals from the famous Champion Mine of Michigan. This piece has some of VERY BEST, classic, dendritic growth patterns that I have ever seen on a copper specimen from any mine. The stem or trunk copper crystal runs the entire length of the piece and the cuprite-enhanced patina is excellent. Ex Kevin Brown Collection. It is utterly classic for the locale in terms of structure and crystallography 6.6 x 3.8 x 3.2 cm
A very rich, old-time, slabbed CABINET ore specimen of lustrous, deep blood-red, massive cuprite in malachite from Nevada with the label glued to the back. Ex Richard Hauck Collection. 10.3 x 7.3 x 2.6 cm
Rich and pretty green malachite on a bed of cuprite "fingers" - a very interesting and attractive copper-mineral combo specimen from the classic Tsumeb locality. Very rich for primary malachite from tsumeb, as well 10.4 x 5.2 x 2.9cm
Sharp, very attractive , classic example of this famous pseudomorph! However, its MUCH sharper than normal, and really exquisite in person. It is so sharp, in fact, she had it labelled as a garnet from France...but it ain't! 0.9 x .8 x .7 cm
