An excellent and very interesting chalcopyrite crystal that is partially coated with tenorite and hematite. The crystals is very sharp and, as usual, twinned, showing nice stria and re-entrant angles delineating the twinning. I obtained this specimen in an exchange with the famous French collector, the late Alexandre Delerme, when he visited my home in 1997. Displays perfectly!
