COPPERCalumet MineCalumetMichigan4.3 x 6 x 3.5 Inches 11 x 15 x 9 Centimeters Large CabinetThis is a copper cast specimen - The copper was within a chunk of quartz and other host r ocks that was chemically "burned" away leaving the copper. It's been treated to maintain a metallic look but there are a few areas with patina/oxidation/malachite. It is very sculptural in appearance and not something you see everyday - Displays great in each and every orientation! Show more
