A fine, sharp, well crystallized Butte Covellite collected in Butte before 1966 by Paul Heissfeld. Comes with Heissfeld and Larry Conklin labels. Larry notes: An excellent mass of large crystals and no matrix. Classic form and habit, very good blue and gold iridescence amid the dark crystals. Covellite crystals of any size are rare and best known from just two localities, both long closed.
