This is a classic, large, lustrous, spear-point of deep navy blue azurite. The lower portion of the crystal has actually begun its long, inexorable, journey of becoming pseudomorphed by velvety, green, chatoyant malachite. The contrast is beautiful! The size and quality of this specimen from the now closed Tsumeb, leads me to believe that this specimen predated WWII. It is a ridiculously large crystal for the price, with a very fine, broad, textbook termination.
