A VERY AESTHETIC, classic, old-time specimen of cuprite-coated, dendritic, spinel-twinned copper crystals from the famous Champion Mine of Michigan. This piece has some of VERY BEST, classic, dendritic growth patterns that I have ever seen on a copper specimen from any mine. The stem or trunk copper crystal runs the entire length of the piece and the cuprite-enhanced patina is excellent. Ex Kevin Brown Collection. It is utterly classic for the locale in terms of structure and crystallography 6.6 x 3.8 x 3.2 cm
