Pyrite cubes never get old. There are some that insist these things are fabricated, but they are completely natural, and thus a favorite of collectors. This particular piece hosts a large 3.5 cm Pyrite cube, and just for fun, a tiny .5 cube nestled right next to it. Both cubes are perfect – an  amazing piece!
