    My ego is forcing me to respond. If I am wrong, I am sure that
    someone will let me know. I don't have any reference works here so I
    am doing this by memory. 

    The cleavage directions run along the octahedral faces. Anyone that
    sets diamonds for a living has watched a few diamonds cleave from
    the girdle past the culet. The Octahedron is sawed into two stones
    of unequal size to optimize the diameter of one of the stones. The
    table is parallel to the cubic faces.
