A HUGE twinned quartz, showing symmetric twinning at a near-90 degree angle, called Japan Law. This piece is really in pretty good shapr considering the size, as most of these are heavily damaged from the locality. It has only very, very minor dings on a few edges, one small contact on a lower wing, and a contact at the lower-center where it grew against a very small crystal in the pocket. Otherwise, the display face is pristine and visually it looks so anyways, at first glance. This is a very dramatic piece for the price, given the sheer size of it!!!
