TZ66Z2: A novelty at Tucson 2014. Aggregate of extraordinarily elongated Chalcocite crystals and coralloid growths completely coated by iridescent Chalcopyrite, with dominant blue and violet shades. By recent reports, it seems that in some cases the Chalcocite crystals are partially replaced by Djurleite.
