An aesthetic, two-sided specimen of lustrous, radiating green blades of atacamite from a very UNCOMMON Australian locality, Raventhorpe. I particularly like the way the atacamite blades radiate out from the hole in the center of the specimen. Atacamite is uncommon copper chloride and this is a very fine specimen of the species. Ex Eugene Meyer Collection. 4.5 x 3.1 x 2.3 cm
