What Will a Diamond Certificate Tell You?
The certificate will state your diamond's 4 Cs: color, clarity, cut, carat weight. It will describe the diamond's shape, measurements, table and depth percentages, and grade the polish and symmetry. It should also comment on characteristics like fluorescence, graining, and imperfections.

Who issues a Diamond Certificate?
Diamond certificates are issued by independent gemological laboratories. There are several grading laboratories, the most prominent being: the Gemological Institute of America (GIA), the European Gemological Laboratories (EGL), the American Gem Society (AGS) and the International Gemological Institute (IGI).
