dr61 ((COPPER)), $10 MINIMUM BID, Kennecott Mine, Ray, Arizona, 3 cm in length, Miniature | |
Here is a rare and unusual Copper specimen collected pre 1975. Pseudohexagonal copper crystals appears to result from cyclic twinning around the 3-fold axis; note that some are scepters with a cube corner at the top of the scepter. Collected pre-1975. Again very rare and unusual crystal form |
