WOW! This is an unusual pseudo-cubic crystal of columbite with edges to 3.3 cm long. The crystal is deep black in color, with a nice luster but with slight pitting on the faces. One side of the crystal is contacted. Very large example of the classic Brazilian columbites. A couple of collection labels come with piece.
