The Diamond Quality® Report
AGS Laboratories' new proportion-based Diamond Quality® Report is based upon the patented American Gem Society's light performance system. The report offers a complete grading analysis of the 4Cs: Diamond Cut, Color, Clarity and Carat Weight, and features word descriptors ranging from Ideal to Very Poor in order to give a clear, concise explanation of the diamond’s quality. The Diamond Quality® Report is the gold standard in proportion-based grading reports.
