Amazing and very uncommon polished Azurite and Malachite specimen from Poteryaevskoe Mine, Rubtsovskoe Cu-Zn-Pb deposit, Russia. It displays gorgeous royal blue color due to Azurite and green due to Malachite - very vivid and rich combination. Featuring bright Malachite hemisphere enclosing Azurite core which gives superb contrast. For references see the issue of The Mineralogical Record vol. 45, # 4, July-August 2014. In superb condition. Polished.
Beautiful!
