Copper (Spinel-Twinned)
Cabinet, 13.8 x 4.4 x 3.8 cm
Champion Mine, Painesdale, Houghton Co., Michigan, USA
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.
