This outstanding full miniature specimen has all the qualities you could ask fo rin a historic copper in calcite : good luster, clarity to the calcite, rich inclusions, and good aesthetics. However, more than that, it has also free vein copper and a crystal of copper in association, which is uncommon. This is most certainly an old specimen, and many came out prior to the early 1900s. For the size, and beauty, I regard it highly. They are seldom available today, and remain almost unique to Michigan's historic copper district
From a famous find of 2006, this is a superb example of spinel-twinned copper crystals from a one-time erratic find. All came from a single large boulder found by Stan Esbenshade, and carefully trimmed out. This is a complete floater, terminated all around and formed in a spongy mass of strange copper float material. This is a particularly gracile and elegant, slightly curving, specimen composed of a central twinned crystal from which outgrowths shoot to the sides. This was a onetime find, and now these are hard to find for sale today. Classic!
From a famous find of 2006, this is a superb example of spinel-twinned copper crystals from a one-time erratic find. All came from a single large boulder found by Stan Esbenshade, and carefully trimmed out. This is, for the size , unusually thick - much more robust than most. Note the layer of secondary crystallization like wings along most of the central spinel twin. The clear spokes of the central twinned copper crystal provide several sharp flanges to give it added visual impact and size appeal. This was a onetime find, and now these are hard to find for sale today. This is a complete floater, terminated all around and formed in a spongy mass of strange copper float material.
Usually, papagoite is dispersed in veils, but in this piece it is extremely concentrated in richness and in color saturation, right at the tip! This is a phenomenal crystal with unusually vivid coloration. The termination is sharp and complete, unusually pristine. Note also the slight wisps of copper inside, dispersed in the zone of deep blue papagoite. A classic, unique to this locality, such crystals are highly desirable in this quality. Papagoite is much rarer, here, than the ajoite inclusions. MUCH better in person, this is one of the sharpest such examples that I expect to be able to offer. It is from new finds in late 2009.
ex. Marc Weill
This specimen is a very robust and aesthetic cluster of RAZOR-sharp copper crystals to 1.5 cm, arranged in branchlike aggregations that twist and turn about to make this a 3-dimensional "tree-like" shape overall. The crystals are sharp, and there is remarkably no damage or rubbing to the fine, old surface patina. It is complete all around, and displays dramatically in person. Formerly in the Marc Weill collection, this is a very fine cabinet sized copper of unusual appeal for this habit and style of crystallization, rare in such good form. It stands on its own merits as a value and a fine quality; but as a bonus it also is illustrated in the Mineralogical Record book on the Weill collection. 500 grams.

This is a solid mass, composed almost completely by spinel-twinned copper crystals which reach over 3 cm in length. The surface patina is a rich brownish-red, natural and unburned by acid as usual; with the brighter red coloring probably due to a coating of cuprite.The specimen appears to be a floater, with part of the back side covered by microcrystals of a light tan-colored mineral, possibly calcite. Overall this is a more massive piece than on enormally finds from Champion finds, heavy and with good impact and presence.

This graceful and aesthetic, arching copper specimen has spinel twins, to 3.3 cm in length, emanating from a central spine. This is CLASSIC style for the Champion finds! It is , however, unusually elegant in its presentation. The patina color is a rich brownish-red (untouched by acidizing) and this specimen can be viewed from more than one direction since it appears to be a floater. The back side is lightly covered in a crystal druse, probably calcite. Architecturally, this looks a lot like a fish skeleton and so you can see why the nickname "herringbone coppers" has been attached to these. A striking specimen, and a very stylish old classic . Out of all the Michigan coppers, this is really one of the few styles totally unique and recognizable to one specific mine. Absolutely elegant!
ex. Robert Nowakowski
A curving, central spinel-twinned copper crystal, reaching nearly 9 cm in length, is the highlight of this specimen which has literally tens of spinel twin copper crystals in parallel growth supporting it on a pedestal. This graceful and aesthetic, arching copper specimen has dozens of spinel twins emanating from a central spine. This is CLASSIC style for the Champion finds! It is , however, unusually elegant in its presentation. The patina color is a rich brownish-red (untouched by acidizing) and this specimen can be viewed from more than one direction since it appears to be a floater. The back side is lightly covered in a crystal druse, probably calcite. Architecturally, this looks a lot like a fish skeleton and so you can see why the nickname "herringbone coppers" has been attached to these. Striking specimen, and a very stylish old classic . Out of all the Michigan coppers, this is really one of the few styles totally unique and recognizable to one specific mine. This large specimen is of a size and quality to make it stand out dramatically from the crowd, and from other coppers. This specimen is a major, robust example.

A complete floater, this copper specimen looks like a growing bush or tree with the top much wider than the base. The whole specimen is composed of spinel twins of copper, elongated and graceful, to 6.7 cm in length. The patina color is a rich brownish-red (untouched by acidizing) with the brighter red possibly being a coating of cuprite.Another fine sculptural copper from this classic mine. Like others here, it has immediately recognizable, complex form that is very distinct in the mineral world from other coppers. This piece is a robust, complete-all-around display quality
ex. Robert Nowakowski
Emanating from a central spine which itself is a giant, elongated spinel twinned copper crystal, are a series of parallel growth copper spinel-twins to 1.75 cm in length. The crystals have a patina colored a rich brownish-red (untouched by acidizing) with the brighter red probably representing a thin coating of cuprite. In cross section, the specimen resembles a forest or a fishbone. Architecturally, this looks a lot like a fish skeleton and so you can see why the nickname "herringbone coppers" has been attached to these. Striking specimen, and a very stylish old classic . Out of all the Michigan coppers, this is really one of the few styles totally unique and recognizable to one specific mine.

This is a doubly-terminated floater of a spinel twinned copper crystal , measuring 4.0 cm in length. The crystals have a patina colored a rich brownish-red (untouched by acidizing) . Classic Champion Mine style, in this cute miniature. Note that many of these on the market are brightended by acid wash, but this remains in its natural patina and color.
ex. Robert Nowakowski
An exquisite, curving, doubly terminated, spinel twin of copper that is symmetrically shaped like a fish skeleton. A superb thumbnail for the mine, showing the classic style ! ELEGANT! In fact, one seldom sees such finely formed specimens in a thumbnail size from this mine. The crystals have a patina colored a rich brownish-red (untouched by acidizing)
ex. Robert Nowakowski
This "v" shaped cluster of two major spinel twins, smothered in smaller and filigreed offshoot twins, exhibits dendritic growth with a rich brownish-red color and good luster. The crystals have a patina colored a rich brownish-red (untouched by acidizing) . The largest crystal is a spinel twin measuring 5.0 cm in length. Classic form and style!
ex. Robert Nowakowski
A central spine comprising a single robust, elongated spinel twin copper crystal is host to parallel-growth spinel twins of copper, to 1.7 cm in length. The net effect is to give this lustrous, brownish-red specimen an intriguing, three dimensional appearance. Architecturally, this looks a lot like a fish skeleton and so you can see why the nickname "herringbone coppers" has been attached to these. Out of all the Michigan coppers, this is really one of the few styles totally unique and recognizable to one specific mine. The patina color is a rich brownish-red (untouched by acidizing); and this specimen can be viewed from more than one direction since it appears to be a floater. The back side is lightly covered in a crystal druse, probably calcite.

ELEGANT! In fact, one seldom sees such finely formed specimens in a miniature size from this mine. Most are bigger and bulkier. This features a central, curving, doubly-terminated, spinel twin of copper, measuring 5.1 cm in length. This graceful core crystal is offset at right angles by smaller parallel-growth spinel twin crystals. The crystals have a patina colored a rich brownish-red (untouched by acidizing) which was so classic for these pieces. Aesthetic!
