A reference sample of bright reddish-orange jeromite on a cluster of partial quartz crystals. Jeromite is a rare arsenic, selenium, sulfur glass-- in previous years you would only see it as a coating on small, individual quartz crystals. Recently however, there was a pocket discovered with larger specimens, and more jeromite. This is a good reference.
