A very showy and fine, arborescent cluster of sharp, elongated, two-toned copper crystals with a nice patina from the famed Ajo District of Arizona. Some of the crystals are also lightly hoppered. This fine, two-sided copper has excellent aesthetics. The top crystals look like a fantastic animal/insect head with open jaws, large teeth and two ears (a dragon?). Ex. George Elling Collection.
