Description

 This is a specimen of pyroxmangite from one of Colorado's most famous old gold mines. It was and still is referred to as rhodonite, but an analysis in 1976 revealed that the mineral is actually pyroxmangite. This specimen shows a nice rich pink color in contrast to the dark sphalerite and some chalcopyrite.
