Locality: Bisbee, Cochise County, Arizona. Size Class: Large Cabinet. Collection: Schertz Collection. Bisbee is the classic USA locality for azurite, and all things copper and oxidized (malachite, cuprite, etc), but although it was once the largest copper mine in the world it has produced surprisingly few actual copper specimens in its lifetime. Native copper, for some reason, is relatively rare there. This is a huge, 5.3 pound specimen of solid copper, composed entirely of complexly intergrown crystals! The mine operated from the 1890s on and there is no telling when it came out, although it is undoubtedly an old specimen as little was found here in modern times. This rare piece is complete all around, and has a wonderful horizon row of sharp, upright-pointing crystals. It comes with a custom display base. Size 17.8 x 12.7 x 6.1 cm
