I love the way the light flashes off of dozens of perfectly parallel faces on this very choice jacare (elestial) smoky quartz crystal.  As you turn it in the light, each side suddenly bursts forth with blazing hot spots bouncing off the multiple glassy faces on the crystal.  The top of this floater is covered with flat faces, and the bottom is re-healed.  This is a highly aesthetic and very appealing elestial quartz.
