What Is A Diamond Certificate? Do You Need One?
Diamond certificates, also known as diamond grading reports, are offered by independent gemological laboratories such as GIA (Gemological Institute of America) and EGL (European Gemological Institute). A gemology laboratory grades a particular loose diamond on various quality factors such as color, clarity, polish, symmetry and florescence. Certificates offer consumers an extra layer of confidence that the diamond is authentic and as described on the website. In most cases no mention is made about the value of the diamond.
