Description: Copper Locality: Quincy Mine, Hancock, Houghton County, Michigan, USA (Locality at mindat.org) Size: cabinet, 15.9 x 9.2 x 6.0 cm Copper An elegant, arborescent crystal cluster just rising up off a well-trimmed matrix - it is rare to find such large crystals in any case (cluster or not), and on matrix even less common. The matrix has epidote and quartz in it, as well as rock. The copper is solidly embedded - this is no frail treelike growth, but a solidly connected cluster. The cluster overall is flattish, mostly about 1 cm thick; though smaller fat crystals poke out in a few places. Ex. Richard Hauck Collection.
