This unusual example of Quartz phantom exhibits a rare habit: the phantoms alternate purple/black/purple/black as they travel through the Quartz crystal. This came from one small pocket about two years ago. I have not seen any more since then.

The termination is pristine, only a tiny chip near the base.
