Top quality is what this quartz crystal is. Very clear on the inside with a few wisps of white. Also a few external natural etch marks appear. This crystal appears to have grown on hematite and displays hematite inclusions inside the crystal. As well some of the hematite matrix appears external to the crystal on the bottom.
