A hand-sized, SHARP galena crystal of some significance because it is from the old lead district in northern Illinois, predating the discovery of the more abundant Missouri lead belt. Valid, antique crystals of galena from Galena are super-rare and this is not only a valid one, but a huge crystal in good condition for the locality. This composite crystal, consisting of a smaller cube in the back merging into this beautiful cuboctahedron, weighs 9 pounds. It is mostly complete on the back, as well. I have not brightened it chemically by cleaning it, to preserve the antique look.
