    Blaine, I think the first problem with dealing with the terms you are
    using is that most stones are not sold with lab certificates and
    therefore cannot be quantified in the format you are suggesting.  The
    second problem is that most jewelers don't have access to the
    equipment and therefore cannot reference the color system.  The third
    problem is that while machines may be able to quantify the amount of
    color in a gemstone they cannot quantify the cut, which dramatically
    impacts the way the color "works" in a stone.  They also are not able
    to distinguish the amount of inclusions in a stone.  It is not only
    the color that makes a colored stone valuable.  On top of all of this
    everyone has a different perception of beauty.  One person's fine
    dark blue sapphire (with whatever numbering system attached to it)
    will not necessarily represent another person's ideal color. Daniel R.
