Fabulous specimen with a good amount of Gold intimately associated with silvery Coloradoite. Some of the Gold shows wire development. There are three spots which show prismatic crystals of Krennerite. These have slightly different goldish color in the right light, and they also exhibit cleavage. Coloradoite does not have cleavage.
