The Champion Mine coppers are quite distinct among worldwide coppers, as you can see here from the style of copper shown. The copper crystals are twinned, and thickly intergrown like in a weaving, all supporting the others to make for a robust, skyscraper-bones-like cluster. A slight cuprite patina gives this one its typical reddish color. To the copper-lover, the Champion Mine pieces (such as this one) are absolutely distinct and recognizable. They seldom turn up for sale, only in old collections . This is aparticularly gracile-looking and attrractive example with its original patina, whereas many have been acid-cleaned over the years to make them in my opinion, too bright.

ex. Jason New collection Very closely resembling Christmas trees is this aesthetic cluster of parallel growth, spinel twinned, lustrous, copper crystals with variegated patina. The largest of the spinel twins measures 5.0 cm in length. True there are larger groups, rarely available, but for sheer quality and beauty, this specimen is just hard to beat. It is one of the most elegant such specimens I have seen, and is a large miniature or small small cab. It has much more style than most, as they tend to be singles and this is a nice triple!
