Measurements: 42 x 14 x 11 mm
Description: A quartz crystal with a light amethyst cloud and negative crystal inclusions just below its midline. The two biggest termination facets have lovely raised patterns and one of the shaft facets have numerous (extremely minute) quartz crystals on it (image middle left).
The bottom part is slightly milky, and towards the middle are a few cloudy streaks, caused by hundreds of extremely minute, trapped gas bubbles.
The termination appears to be perfect, but there is a very small nick near the ridge of one of the shaft facets. About a third of its length (lower part) has prominent pressure marks stretching over just more than 2 of the shaft facets.
