Summary

[edit]
Description
English: Copper
Locality: Pewabic, Houghton County, Michigan, USA (Locality at mindat.org)
Size: large cabinet, 30.0 x 24.8 x 8.1 cm
Copper with 1800's era drill impression
This is a huge copper specimen with a thick 12-inch crystal perched on a natural pedestal of smaller crystals. Its a floater, complete-all-around, and with really impressive 3-dimensionality. This crystal has, in its middle, a souvenir of the pre-1900s mining technique of hand-drilling. This impression would have been left by a cold steel drill bar that was hammered through the rock by two strong men, alternating turns while another held a candle. The trick was to aim for the candle's reflection on the polished end, and not to have the hammer slip and hit your buddy holding the bar in place. It was not the easiest of techniques. I find this to be a fascinating specimen. So did the Seaman Museum folks. Yes, technically it is "scarred", but its in such an interesting manner that to me this is definitely a museum-style piece. Ex. Seaman Mineralogical Museum Collection.
