This is a huge, lustrous smoky quartz crystal that not only has an Alpine-like gemminess to it, but most remarkably, is a DOUBLY-TERMINATED FLOATER! It features multiple points on either end, and beautiful staggered growth around the periphery. I could only find one ding on this whole huge crystal. Very rare and just astonishing! We saw only this one monster and a few smaller ones at Tucson, and grabbed all. 13 x 8 x 6 cm
