A large, intricate cluster of untold numbers of tourmaline crystals, from the nearly invisible to 4 cm! In fact, the cluster is a floater, cemented together by thousands of micro-crystals, so nearly all the crystals are terminated, all the way around this specimen! and all tourmaline!! this is much better, and more green, in person. There is no attachment area with unterminated crystals. ex Ed Ruggiero collection, purchased in the 70's. It IS a remarkable piece for the overall aspect of it, and the sheer amount of tourmaline in one bundle! 9.9 x 6.5 x 6.0cm
