Description:  A clear, double terminated, gemmy quartz crystal with inclusions of minute balls of clinochlore. Follow this link for a microscopic image of one of these in a similar crystal, and more information. The minute indentations on the surface are where these balls used to be, and have since eroded, and stained by (?)goethite.

One of the termination points has a minute nick, and the other termination has a small pressure mark, and a bigger one across its facet. Otherwise only a few very minute nicks overall.
