| dbar COVELLITE and CHALCOPYRITE pseudomorph after COVELLITE (AKA GOLDEN COVELLITE), Summitville, Rio Grande county, Colorado, 4.5 x 2.5 x 2.5 cm | |
 | These pseudomorphs (Golden Covellite) are well known from two locations: Butte, Montana and Summitville, Colorado. In this one, most of the blue Covellite is pseudomorphed to the brassy Chalcopyrite but traces of the original blue can still be seen. Nice classic miniature. |
