Iridescent twinned Chalcopyrite w/ Quartz (Carlton Davis Coll.)

Item Description

The Bandora Mine, near Silverton, has produced some of the finest chalcopyrite and quartz specimens ever found in Colorado and this is a stellar thumbnail example. The striking, sharp, interpenetrating, chalcopyrite twins are beautifully iridescent on the bright, golden-brassy, lightly striated crystals. The gorgeous little spray of quartz needles is a fabulous accent. The Bandora Mine was intermittently active from 1884 to about 1950. This cutie is from finds in the early 1980s. Ex Carlton Davis Collection.
