Double/Multi-Terminated Quartz Crystal with Large Moving Bubble - NBB 082

"Big Bubble" quartz crystal with large moving bubble

Measurements:  69 x 44 x 42 mm 

Description:  A double terminated quartz crystal with one of its terminations being multi-terminated. It has areas of light smoky colouring and numerous gas inclusions. The main feature of this crystal is its large moving bubble ( 6 x 12 mm)

The bubble moves from just below the main termination ridge, well into the termination. Because of all the gas inclusions, it is not easily visible on these images. Therefore we have deliberately darkened the top right image (same as one just below it) so that the bubble is more visible.

There is a small blow-out (view image bottom left), and some damage adjacent to bits of attached limestone. Most of the termination facet surfaces have a slightly dull appearrance. The terminations have a few minute nicks.
