Standing an impressive 20 inches tall, this is a very fine "cathedral" geode of amethyst, not only filled with sparkly, lustrous crystals, but the amethyst crystals have pseudomorphed an earlier generation of large, euhedral quartz crystals. So instead of the usual "flat" wall of amethyst crystals inside, this one actually has dimension and structure, with these pretty spikes poking out in all directions. These fingers seem to be composed of amethyst pseudomorphed after calcite, with a secondary generation of amethyst coating! Very different from the usual "cathedral" amethyst - will make a fine centerpiece for any room! 48.9 x 18.6 x 11.5cm
