Copper coated by Chrysocolla
stock #24.1-069
Bou Nahas Mine, Oumjtane, Anif Cercle, Tingir Province
Draa-Tafilalet Region, Morocco
9.4 x 6.7 x 1 CM (cabinet)
price: $150


Native Copper crystals in a flat, lace-like branching form that are covered with green Chrysocolla. In fine condition as seen, from a locality that has begun to produce some very attractive Copper secondary minerals and an occasional nice Copper like this. The Chrysocolla is a fairly thick outer coating but it is still possible to see the shapes of the underlying copper crystals, including some spinel twin forms. Choice.

HOLD Copper and Mimetite etc
stock #HOLD 16.1-664
Tsumeb
Otjikoto Region, Namibia
4.1 x 3.2 x 2.3 CM (miniature)
price: $125
Pre Tucson

An unusual multi-specie piece from the incredible Tsumeb Mine. Native copper in branching fingers and thin wires are protruding from a complex matrix with a few yellow Mimetites crystals among other species. Tsumeb is famed for its odd mixtures of species, forms and chemical elements. A cute miniature that has the uncommon combination of Copper and Lead elements.

Native Copper - crystalized Cornish
stock #22.1-169
Trevassack Quarry, The Lizard Penninsula, Goonhill Downs, Mawgan-in Mene
Cornwall, England
6.4 x 3.9 x 1.4 CM (small cabinet/ large miniature)
price: $290
Fall 22

Classic Native Copper tree-like form with a colorful patina is perched on a shard of matrix. In fine condition with some slight iridescence in strong light, this is a an older piece with three previous collection labels included. This is from a less well-known locality at this former serpentine Quarry. The Copper crystals are distinct though crude, flattened and elongated having grown in a narrow seam. Some adhering Serpentine and Chrysocolla add a nice accent.

Copper after Azurite rosette
stock #21.1-529
Copper Rose Mine, Georgetown, Grant County
New Mexico, United States
2.9 x 2.6 x 1.9 CM (thumbnail)
price: $250
Post Tucson 2022

A classic USA pseudomorph with Copper replacing an Azurite crystal rosette. This piece also has begun an alteration on the Copper as well to a Chrysocolla and Tenorite. The whole piece has an interesting softness to the Copper, it almost looks slightly melted. This still has a distinctive form and looks fine from every side. No damage, a nice example of this replacement from the aptly named Copper Rose Mine.

Copper - spinel twin crystals
stock #21.1-318
Dzhezkazgan Mining District
Karaganda Region, Kazakhstan
7.5 x 1 x .6 CM (cabinet)
price: $390
Late Summer 2021

Elongated spinel twin crystals of copper in a chain form are topped with a tiny "tree" of copper wire crystals. Super esthetic and in perfect condition from the amazing find about 12 years ago in Kazakhstan, this is a textbook perfect example. The Copper has a dark red patina on one side and a more metallic on the other. The red color may be the result of Cuprite coatings and alterations on those faces. An elegant and delicate form, this is very impressive in person and the little tree really makes this remarkable.

Copper with Malachite and Analcime
stock #16.1-450-(CN4044)
Cliff Mine, Pheonix, Keweenaw County
Michigan, United States
6.9 x 5.8 x 5.9 (cabinet)
price: $1250
Early summer 2021

A cluster of Copper crystals of many sizes, most being complex dodecahedrons. Malachite encrusts the Copper making a great color contrast. Scattered small Analcime crystals, a few of which are transparent, add a further contrast. An older specimen, ex. Charles M. Noll collection, this displays well from any angle. Close exam shows the smallest Copper crystals are super sharp, textbook perfect nestled between the medium and large sized crystals that are a little more crude though still distinct. A fine Michigan Copper that is a bit different and is especially showy in person.

Copper - elongated spinel twin chains
stock #AX7-048-(647)
White Pine Mine, Ontonagan County
Michigan, United States
9.7 x 3 x 1.9 CM (cabinet)
price: $660
new year 2021

Elegant branching tendrils of Copper in a treelike tangle from the White Pine Mine. Close exam shows these to be delicate chains of elongated Copper crystals. This locale is a classic locality for fine Copper and Silver specimens, this one is especially esthetic, and has a nice patina. Ex Larry White collection, Larry had excellent taste for native metals and esthetic compositions. The White Pine mine was famed for its spectacular branching coppers. Specimens like this piece are very very different from most other locales in the Upper Peninsula, and for that matter anyplace else.

Copper - branching crystals on matrix
stock #20.1-824
Cliff Mine, Pheonix, Keweenaw County
Michigan, United States
6.2 x 3.6x 2.5 CM (cabinet)
price: $80
new year 2021

A tree of crudely crystallized Copper 3.5 CM tall branches from this blocky matrix. A few small chunks of colorless Calcite are on some branches as well, adding some contrast. The Copper branches are locked in the matrix along a line of small holes and are able to be moved several degrees but are still firmly held. The movement of the copper on the matrix is an oddity and not at all common.
