Aurichalcite, Hemimorphite
79 Mine (79th Mine; Seventy-Nine Mine; Seventy-Nine property; McHur prospect), Chilito, Hayden area, Banner District, Dripping Spring Mts, Gila Co., Arizona, USA
Small Cabinet, 7.5 x 5.8 x 4.4 cm
Another interesting Arizona copper-mineral specimen, this one from the classic 79 Mine (from recent re-mining there for specimens). Here is a ribbon of deep turquoise-blue acicular crystals of aurichalcite (actually gemmy on close inspection, one of those minerals that is incredibly beautiful as a micromount with its gemmy, colorful crystal sprays) -- intergrown with sparkly, colorless crystals of hemimorphite. GORGEOUS!
