White Pine Mine, Ontonogan County, Michigan, U.S.A.
This is another exceptional specimen from the White Pine Mine that shows genuine cubic copper crystals (instead of just pseudo-crystalline aborescent form). At first glance this thumbnail specimen appears to consist of branching, arborescent Native Copper, but close examination (especially under a loupe) shows impressive crystal form. The formations are made up mostly of hundreds of tiny, intergrown flattened cubes that show a rather dulled copper-red color and equally dull metallic luster. At least one elongated cube is clearly visible to the naked eye, having dimensions of over 2 mm on the square faces. There is no apparent damage to the piece.
