Since the way it is cut (proportioned) determines the amount of Brilliance/Sparkle, The major Gem Labs have begun to provide CUT GRADES with their Diamond Quality Certificates. The "G.I.A." uses a five grade system from EXCELLENT to POOR, the AGS makes use of their numerical system of "O" being the best to something like "5" being the least.
