Quartz Crystal with Light Smoky Patches - NBB 002

Quartz crystal with light smoky patches and moving

Measurements:  98 x 62 x 43 mm

Description:  A quartz crystal with light smoky patches, lovely gas inclusions and a flat, slowly moving bubble, about 10 mm long (in the crystal's lower part, image 2nd on left). 

Below the lower termination ridge is a flawed area (about 30 x 10 mm), adjacent to a neat pressure mark. Further down from it is a large area with interesting growth marks and numerous small facets (image bottom right). About three quarters of the shaft facet, directly below the start of one of the termination facets (image 2nd from the top, right and bottom left) has chipped off, visible when tilted in light, otherwise not very obvious. This is possisbly because it grew at a sharp angle, and became detached there. The narrow female termination has a few small nicks. 

The specimen displays well on a flat surface, at a sharp angle.
