A huge 14.5-cm crystal of calcite perched on a bed of smaller calcites, some of which are coated with iridescent chalcopyrite throwing off a sparkly rainbow of colors. The big crystal is perched at an aesthetic angle, and is complete and perfectly terminated on the "important" end (the lower termination was a contact so is not complete). Ex. Dave Stoudt Collection, acquired by him in 1984.
