"The third installment, published in Fall 2004, is “A Foundation for Grading the Overall Cut Quality of Round Brilliant Cut Diamonds.” Thomas M. Moses and co-authors turned to visual observation testing on actual diamonds for brightness, fire, and overall cut appearance in order to check previous metrics and develop new ones. On the basis of their findings, the team constructed the foundation for the GIA Diamond Cut Grading System, which will provide a single overall grade for cut quality for standard round brilliants. This system will be incorporated into the Institute’s educational programs and diamond-grading services."
