A well crystalized cluster of Gypsum (Selenite) with rich green inclusions and encrustations of the rare mineral Herbertsmithite. This find has produced what are certainly the most esthetic examples of this specie as Herbertsmithite is not usually a "display" grade mineral. Recently Herbersmithite was found to have unique properties of changeable magnetism and with quantum spin properties. This was picked up in some of the popular media and somewhat exaggerated as news, even being called a "new form of matter". There was a brief period where tiny crumbs were being sold for high prices. Despite the inaccurate hype this is a remarkable mineral and on this specimen it is actually attractive.
