A KILLER Yaogangxian Mine combination specimen. A water-clear, very pastel-green fluorite cube with gorgeous, purple phantoms is aesthetically nestled in the side of a splendent, super-sharp, metallic-silver arsenopyrite crystal. The arseno crystal has textbook crystal form and beautiful, etched faces. This complete all-around, super piece has only the slightest contact on the back. The Yaogangxian Mine produces some of the finest arsenopyrites in the world, comparable to those found at Panasqueira and this is a very fine example.
