Description

Old timer from the Krantz stock: malachite with in part nice banding. Please note: i suspect that the specimen was cut by Krantz much later than the specimen was found (there was another half labeled to be found at the Demidoff Mine in 1880. The label hinted to Robert Damon). The sample was only cut, not polished (i did not polish it to preserve the state it was when i got it from Krantz). This sample is the half of the half - i unwillingly stepped on it so i got two specimens :D
