Thank you for your interest in AGS Laboratories. We set the standard for Ideal cut diamonds. We were the first diamond grading laboratory to develop and offer an objective standard to determine how well a diamond has been cut. Later, the laboratory expanded from offering a cut grade on round brilliant diamonds to fancy shape diamonds. When we say that the AGS Laboratories sets the standard for diamond cutting we back it up with proven research, and that research is translated into our Diamond Quality^TM Reports.
