Researching Diamond QualityIt is important for you to know the quality of a diamond so that you know how rare it is. This rarity is what you pay for. The quality grade alone does not tell you whether a diamond is beautiful. Beauty is a complex combination of all diamond factors, and the result is a total package that appeals to the individual. The Importance of CertificatesWe strongly urge you to buy a diamond that comes with an independent lab grading report. There are several laboratories that will evaluate a diamond according to the factors that make it unique, and provide paperwork called a certificate, to identify it. These firms do not buy or sell diamonds, nor do they assign a value, so they can provide an unbiased opinion of a diamond’s quality factors. The Gemological Institute of America, or GIA, created the diamond grading standards and provides excellent lab grading services. There are several companies that also provide grading reports: European Gem Labs, or EGL; International Gem Institute, or IGI; the American Gem Society, or AGS; and HRD. A grading report or an appraisal from the Jeweler, while important for value and insurance purposes, is not the same thing as an independent report.There are 4 basic factors that help determine the relative rarity of a diamond (we have separated Cut into Shape and Proportions).
