Just a neat specimen from historic Cornwall, better know for tin mining, but many started in the zone of Copper mineralization. This specimen is likely a juiced up piece which had undergone intense influx of copper alteration, since most of the Malachite and Azurite appears to have replaced the feldspar and mica throughout. (maybe I'm full of &*it). The large red spots are the Cuprite.
