Absolutely gorgeous, polished Azurite hemisphere. It is a half ball with an amazing royal blue color - very vivid and rich. Featuring Azurite aggregates with one marvelous darker blue band at the rim. At the center are seen irregular cavernous formations with crystallized Azurite. Some minor Malachite and one Cerussite crystal on the back side are seen too.  For references see the issue of The Mineralogical Record vol. 45, # 4, July-August 2014. In superb condition. Polished.
Killer!
