A beautiful, aesthetic, elongate, two-sided copper specimen of dendritic, spinel-twinned copper crystals with a nice patina from the classic Champion Mine. The dendritic pattern of the sharp, spinel-twinned crystals is outstanding. CHOICE material from the Marty Lewadny Collection. NOTE that this started the weekend labeled as Mufulira Mine, Copperbelt Province, Zambia as this label was with the piece, but Marty contacted me when he saw it and made the corrrection himself so I am confident of the change to the now-indicated locale. 4.2 x 2.4 x 1.8 cm
