Aurichalcite is relatively uncommon from the famous mines at Bisbee. This remarkable combination specimen is richly covered with radial sprays of powder-blue to pastel-green aurichalcite needles. The aurichalcite is associated with clusters of glassy, colorless hemimorphite crystals, some of which are included with aurichalcite. This is a very uncommon association specimen from this classic locale and is almost certainly old-time material, dating to prior to World War I. Ex. Dennis Mullane Bisbee Collection.
