Large single Azurite crystal with a small attached crystal that is altering to Malachite. There is also some alteration to Malachite under the surface of the main crystal that gives areas of 'electric' blue color. Fully terminated and complete all around. There is one chipped area on the side with the small attached crystal (though most of what you see in the third photo is natural etched growth), otherwise it's undamaged. Comes with an old Geary Murdock collection label.
