Tsumeb is famous for above all else, the historic large azurite crystals such as this which primarily came out of the older workings. Without question, this azurite specimen is spectacular and looks good both back and front such that it is really hard to decide which to present first to you. On one side, a large Azurite crystal dominates the piece at 6cm with a 3.8cm sidecar crystal in subparallel growth and a third crossing diagonally down at the base (2.6cm). They exhibit good luster and also display isolated "spots" of Malachite that are actually two-dimensional sprays of radiating, acicular crystals of velvet green contrast for a stunning effect! On the opposing side, the large crystal is superbly lustrous and shows a 2.5cm crystal in slight relief with the same great luster. There are a few Malachite sprays on this side: one located on one of the terminal faces, one near the base, and another small one at center right, providing dramatic aesthetics. With strong backlighting directed along the edge of the crystal, the big Azurite shows the deepest royal blue possible! The addition of the rich green, 2-D Malachite sprays adds immensely to the beauty of the specimen by its minor contrast. This piece has sharp faces and edges with only tiny, trivial edge chatter very locally. This Azurite is even better in person - almost as much of a "jewel" in appearance as these can get. It is simply agonizing to decide which side we liked better...One might point out that Milpillas in Mexico recently produced so much azurite that it rendered that species briefly among the most common on earth for collectors - and that is true, but they did NOT look like this.
