Azurite rosettes to 1.3 cm on malachite from the 200' level of the Czar Mine at Bisbee, Arizona. The specimen is pictured on p. 649 of Arizona VI, July-August 2015 Mineralogical Record. Although noted in the magazine as a former Ben Williams piece, I received visual confirmation from Bill Larson that it was not part of the historic Williams lot he obtained. Former Jim and Gail Spann collection. Tom Spann photo.
