A miniature-sized piece of iron-stained Quartz veinstone contains a small area (1 cm in length) of grey metallic bismuth telluride mineralization marked by a small red arrow. These bismuth tellurides are dominated by Pilsenite, a member of the Tetradymite group. Although not especially aesthetic this piece is from Stone Cabin Gulch, Hidalgo County, New Mexico, USA, where few specimens of the tellurides are preserved. It is from the superb systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 & 1956-2021). Show more
