This is a copper cast specimen - The copper was within a chunk of quartz and other host rocks 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!

EVERY SPECIMEN INCLUDES AN IDENTIFICATION CARD
