Superb complex of brilliant Hausmannite pseudo-octahedrons, ranging up to 1 cm on edge, accented by two gemmy pink datolites (a rare and unique combination) which range up to .8 cm. A superb thumbnail, in every sense. This piece is highly symmetrical, and also is bright and reflective. Ex. Charlie Key.
