Copper, Tenorite
Thumbnail, 1.9 x 1.1 x 0.7 cm
Phoenix Mine, Phoenix, Keweenaw Co., Michigan, USA
Cubic copper crystals are RARE from Michigan's Copper Country, but this cute and aesthetic thumbnail is LOADED with elongated, stacked cubes in a dentritic pattern. The black tenorite coating and the bit of quartz add a very nice touch to this very fine and sculptural old-timer from the famous Phoenix Mine. Ex. Seaman Museum Collection.
