An old timer, since the mine closed in 1925, this spinel-twinned copper specimen exhibits a slight chatoyancy along with a dark copper color. The largest of the crystals measures 2.7 cm in length. All the crystals show stepped growth striations. It looks "twisted" and is overall just an unusual copper country specimen.
