This classic specimen from the French Creek Mines features sharp, iridescent chalcopyrite crystals in a brightly colorful golden hue. The crystals are sharply formed and many are hoppered, in an unusual triangular tetrahedral shape. The matrix is magnetite. This is a great old-time specimen from a long-closed, highly regarded locality. From an old collection that was put together between the 1930s and 1960s by Carey Melville, a professor at Clark University. Old hand-written label included.
