This 20.6 gram crystal is a complete floater, unusually crystallized so that at first glance it looks somewhat rounded, but is instead composed of multiple inturned faces that give that illusion. It is a gemmy, internally near flawless stone that has substantial cutting value. Although lacking in large scale sharp geometries, the subtle patterning on the surface is complex and interesting. These are from unprecedented 2009-2010 finds that are just completely unique for the species. Joe Budd photos
