Nice specimen with green Dioptase crystal clusters and yellow Mimetite? crystals on matrix. The Dioptase is on both sides in many areas of this specimen in small sprays of clusters. 

The Mimetite? fluoresces a dim yellow under 365nm long wave UV light.

The crystals are small and magnification is suggested to view them well.
