I am always drawn to these large pyrite cubes-- though so far this is the largest semi-lone crystal I've been able to get. Most of the pyrite crystals from this mine are clustered rather tightly-- to find one of this size so distinct is rather unusual. There are a couple chips, but the piece is incredibly attention grabbing. I had this sitting with the rest of the lot as I was unpacking, and a friend who came by instantly noticed this piece, among all the others. The size of the cube and incredible luster really make it stand out. Even in the pictures, you can actually see the camera and my fingers, and in another you can see the (readable) mirror image of a couple labels in the crystal face. It isn't cheap, but I like it.
