An incredibly large cluster of crystals of this very rare species, seldom seen in anything larger than thumbnails. True, the crystals have some ingrown gossan matrix attached, but the cluster is still huge and bright, and significant for the richness of the species. And it is not totally ugly, just a little earthy, let us say...but, find another! In person, this has a slightly more green color and good luster, as well. CHEAP DEAL!
