This BIG specimen is amazing not just for the beauty of the combination of species, but for the calcites themselves. They grew in two completely different forms, on the same specimen: scalenohedrons, and flat nail-head crystals. Some of the crystals are part one and part the other - just incredible from a crystallographic standpoint! The crystal grew part-way up then rose to a pointed termination in one area, with the rest of the crystal continuing up to a flat top that wrapped itself around the point of the scalenohedron!!
