Pyrite -octahedral on Quartz Classic USA
Emma Mine, Butte, Butte District, Silver Bow County
5.4 x 4.3 x 2.7 CM (small cabinet/ large miniature)
Octahedral Pyrite and milky Quartz in a classic combination from Butte. Additional dark sulphides are present but the main feature here is the lustrous Pyrites and elongated Quartz. In excellent condition which is rare in Butte pieces. Butte is one of the worlds greatest mining zones of the 19th and early 20th century. Good specimens are surprisingly rare, this is a nice one ex Les Hitchings collection.
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.
