WOW! This is an unusual pseudocubic 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 coloumbites. A couple of collection labels come with piece. 3.4 x 3.3 x 3.1 cm
