probably Quincy Mine, Hancock, Houghton Co., Michigan, USA
Cabinet, 13.5 x 9.2 x 2.2 cm
Ex. Andrew Carnegie
This is a structurally unique copper specimen that reminds me of those children's cartoons of a man sitting on the crescent moon. It features a "stalk" of that is curved over by the succeeding growth of each copper crystal on top of the previous one at a slight angle to the right. I cannot figure out what process would cause this to happen other than a slowly rotating environament?! The crystal at the bottom, just sitting there perfectly isolated and straight and yet impaled by the "stalk" curving through it, measures 4.2 x 2 x 1.7 cm in height and thickness dimensions. It is truly a graceful specimen, aside from the significance of the large isolated crystal. The patina is a rich wet-looking chocolatey brown that is simply not conveyed well in the photo. The mine attribute is at Hansen's suggestion having shown it to copper experts some 20 years ago and comparing it to known specimens.
