Native copper crystals are found at many localities around the world but reach their zenith in Michigan's Keweenaw Peninsula, where they occur ion hundreds of deposits in myriad forms and associations. Some of the most prized specimens exhibit large, blocky dodecahedral to modified tetrahexehedral crystals with a rich chocolate-brown patina. This is one such piece, and is composed entirely of intergrown crystals to an impressive ~3 cm, with great patina and form. Classic! Ex - Proctor Family Trust Collection.
