    Everything you said is correct and accurate, but it is still an
    artificial system from the point of use of diamond in the design.
    Whether the stone is flawless D or VVS1 E, the artistic contribution
    to the overall composition is the same. 

    Also transparency of diamond is not taken into account in GIA grading
    system. By transparency I do not mean inclusions, it is what used to
    called "water" Two stones which would grade the same on GIA system,
    but one from South Africa mines and another from India (Golconda)
    will sell for remarkably different sum. I know that example is
    theoretical because Golconda diamonds are not available anymore, but
    for illustration purpose, it is valid
