Double-terminated clear Quartz crystal with inclusions of graphite and moving bubbles inside water pockets (enhydros). This is a crystal I've owned for about 20 years and was the very best of a large lot of similar crystals purchased. There are bits of Graphite (some large to about 5mm) and bubbles moving everywhere when you turn it in hand, really loaded with movement, I estimate there are about 10 pockets with either a moving bubble or Graphite.
