location:
Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia

description:

An interesting and neat crystallized grouping of dark blue to almost black lustrous azurite crystals measuring 3.2 x 3.7 x 4.5 cm in size overall. The main crystal is quite thick and is terminated on top, though most of this termination is coated by tiny crystallized cerussite. There are small glassy transparent crystals of cerussite to 0.3 cm in length spread throughout the specimen. On the "back side" of the cluster is a choice twinned cerussite crystal measuring 0.9 x 0.7 cm. There are many neat smaller terminated crystals of azurite on the "front side" of the main azurite crystal. A fine and choice example for the species from this famous locality! Size: 4.5 x 3.7 x 3.2 cm. Ex Gene Tribbey collection with a data card noting an acquisition date in 1972 at $70; also a previous label from Ret Latta in Rockford, Illinois.
