An old classic from the turn of the 1900s era at the heyday of the original Bisbee mines! This specimen is made up of an adorable set of three stacked spherical clusters of finely crystallized Azurite from the famous Copper Queen Mine in Bisbee. The upper sphere is virtually complete, and it is 1.6 cm across. The luster is very good, and the crystallization is such that the deep, rich blue shows well, rather than the almost black-blue often seen in many Azurites. Very nice aesthetics!
