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.

New Mexico, United States
3.2 x 1.7 x 1.3 CM (thumbnail)
price: $290

Slender, elongated spinel twins of Copper from this classic USA locality. This looks fine from all angles; it comes from the Larry White thumbnail collection. A good example for the location and a choice thumbnail.

A complex branching Copper specimen composed of many small crystals in stacked or aligned arrangements. Good patina, the color ranges from a dark that is almost black to a red copper hue. A multitude of tiny crystals in many divergent habits are best appreciated under magnification.

Copper pseudomorph after Aragonite
stock #20.1-302-(LW1064)
Corocoro, Pacajes Province
La Paz, Bolivia
1.3 x 1.2 x .5 CM (thumbnail)
price: $190
new year 2021

A perfect small thumbnail of native Copper that has faithfully replaced a hexagonal Aragonite crystal. The Aragonite form is textbook perfect and the patina is a choice red copper hue. No damage, complete all around this is both sharper and with better color than usually seen. These pseudomorphs were found more than 30 years ago and not since. Ex Larry White collection.
