Striking polished Azurite hemisphere. It is a half ball with an amazing royal blue color - very vivid and rich. Featuring Azurite aggregates with marvelous Agate like bands with different color intensity.  At the center are seen irregular cavernous formations with crystallized Azurite. Some minor Malachite is seen too. For references see the issue of The Mineralogical Record vol. 45, # 4, July-August 2014. In very good condition. Polished.
Splendid!
