I have this vibrant cabochon of Bluebird Azurite and Chrysocolla wrapped in Sterling Silver wire.  The Bluebird Mine produced gorgeous Azurite and Chrysocolla with slight patterns of Malachite. The Bluebird mine was an active mine from 1950 to 1982, it then was shut down. The material now only comes out of very old estate collections. We purchased this several years ago from an estate here in Arizona.
