Azurite With Chalcoalumite
Bisbee, Cochise County, Arizona, USA
Small Cabinet, 7.8 x 5.8 x 3.7 cm
The truly neat thing about this specimen is that it can be viewed on either side, equally as well. On one side, a botryoidal crust of rich, blue, azurite is coated with a botryoidal crust of light green, chalcoalumite, a fairly rare, hydrous, copper, aluminum, sulfate. Here the chacoalumite spheres reach .8 cm across. On the back side is a vug with a crust of brown limonite upon which is emplaced a druse of sparkling, deep blue, spheres of azurite. Unusual, and very fine!
