subject: The Importance Of Knowing About Diamond Certification [print this page] Each certification process goes by industry guidelines which are provided by the GIA, or the Gemological Institute of America. The GIA lays down the standard minimum criteria across the globe as per the international parameters. The grading of the color of diamonds and gemstones during the process of diamond certification is done by the American Gemological Society. The criteria they employ for rating hue are deemed better than that of the GIA.
In addition, there is the group called Accurate Gemological Labs A.G.L. is an abbreviation for American Gemology Limited. and its European partner, the European Gemological Laboratories (EGL). The AGL's comprehensive reports evaluate the diamond's 4 Cs; this is the organization's major role in diamond certification. But, the EGL follows AGL protocol and, in addition, delivers a report on the different proportions of the diamond. The report is all-encompassing with the inclusion of unique features like angles of pavilion and crown.
International Gemological Institute (GMI) (IGI for short) also shares a certification of diamonds similar to that of Europeans Mentioned also are the angels and crown of the diamond. But, the primary benefit is that they are more affordable than the GIA when it comes to certification. Small and medium-sized diamonds are the most sought after ones.
