The more I look at this specimen the more I am impressed. If you are like me and enjoy the studying the paragenesis of the mineralogy, you will thoroughly enjoy this piece. The color of the Greenockite sets it apart from the rest of the minerals. It is a coating on the surface of the Sphalerite crystals which are black and superb to 3mm. In the open spaces, waterclear Quartz formed at the center and along the outer edges of the vein.
There are only a handful of reported Greenockite in Colorado. This specimen carries a Red Mountain Exploration tag.
