Even more strange, pretty and impressive in person; this is a super-complex floater crystal of smoky quartz, unusually flattened, showing the growth pattern sometimes referred to as "elestial." The crystal is displayable from either side and terminated all the way around. You can't see it from the pics, but as you rotate it, the light reflects off of all the parallel faces at once, demonstrating the crystallographic order amidst what seems to be a confusion of faces. Really impressive! 15 x 11.5 x 2.3 cm
