    Hi Richard, I won't discuss you considerations about business.
    Concerning the light entering the stones, I bring your attention on
    two points: - when photographing stones, I often noticed that the
    facetted gemstones don't look the same way whether there is a white
    background or a black one. I may be wrong, but according to my
    experiments, I am sure that, in the case of clear facetted
    gemstones, light entering from the cutlet enhances the appearence of
    the stone (as long as the stone isn't too weak in color). -
    concerning the cabs, as only low end qualities are cut into cabs,
    they very often are hardly translucent, and not transparent. The
    reflexion of the light only occurs in the very first millimeters
    under the surface, and the light coming from the cutlet doesn't seem
    to cross the cab. But i read that some big and thick cabs were cut
    with a concavity in the cutlet to seem more vivid. Unfortunatly, I
    never saw any. Yann www.webcarats.com
