Diamond Grading Reports

A diamond certificate, also known as a diamond grading report, will usually include a plotted diagram of your diamond and all significant characteristics, including the 4Cs (cut, color, clarity, carat weight).

The report will also describe the diamond's shape, exact measurements, proportions and depth percentages as well as grade the polish and symmetry. It should also comment on the characteristics like fluorescence, graining, and any imperfections in the diamond. This will give you a better picture of exactly what type of diamond your buying to put on your engagement ring.

A grading report does not, however, include an appraisal or any kind of statement of monetary worth of the diamond. Grading reports simply state the scientific facts of your diamond that can be evaluated by highly standardized criteria.

The best way to understand your diamond grading report is to schedule an appointment with your jeweler. This way, he can explain to you each portion of the certificate while visually examining your diamond with you. Grading a diamond is only partially scientific; a brief meeting with your jeweler can help you understand what the certificate really means.

Diamond grading reports assure you of the quality and authenticity of your diamond. As most consumers are not experts, a certificate is an objective comparison. In addition, some insurance may require a grading report if you are planning to insure the diamond. Diamonds for your engagement rings with a grading report are usually more expensive.

Certification of a diamond does not increase the value of your diamond. Certification is only a safeguard for the consumer as it is affirmation of your diamond's authenticity and specific characteristics. Therefore, the certification in itself is a valuable document.

Depending on the laboratory used the process for a diamond grading report can vary anywhere from 2 weeks or longer. The fee for a grading report varies depending upon the carat weight of your diamond. For exact prices, it is suggested that you contact specific labs to get price quotes. Some well-known organizations that provide grading reports include the American Gemology Society (AGS), Diamond High Council (Hoge Raad Voor Diamant; HRD), European Gemology Library (EGL), International Gemological Institute (IGI), and the Gemological Institute of America (GIA). Your local jeweler can help aid you in acquiring a grading report through one of these labs either at the time of purchase or after. Remember to make sure your engagement ring has a certificate!
