Highly lustrous, gun metal-gray, massive chalcocite with a bit of sparkly, royal-blue azurite from the Bonanza Mine of Alaska. This shapely chunk comes with a reallly cool old, faded, 13.3 x 8.0 cm Kennecott Copper Corp. label and has the nickname of "steely glance" Very interesting historic specimen and besides that, who has any minerals from ALASKA anyhow? a rare chance to own one here..... Moreover, this is the original locality for this famous old mining company - I never realized Kennecott mining company actually STARTED in kennecott (they ended up owning Butte and other mines later on). Ex Richard Hauck Collection. 7.9 x 5.5 x 4.8 cm
