    GIA does not have explicit rules that you can ascertain simply by
    looking at their website.  They have guidelines which most people who
    train with them learn throughout the course of their training. 
    Clarity grading is a subjective field and even GIA has multiple
    graders look at stones to ensure that there is some consensus on the
    grades.  I suggest that if you want to learn their method of clarity
    grading you take their courses. Daniel R. Spirer, GG
