Certificates

Diamond certificates, more accurately known as diamond grading reports, are commonly provided with the purchase of a significant piece of diamond jewelry such as a diamond Engagement Ring or a diamond Three Stone Ring. These reports are prepared by independent, certified gemologists from laboratories around the world and can help calculate the specific characteristics of your diamond (color, cut, clarity and carat weight, for example).

What's Included in a Diamond Grading Report?
A diamond grading report will commonly include a plotted diagram of your diamond and significant characteristics, including the 4Cs (cut, color, clarity and 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, raining, and any imperfections in the diamond. Please note: a grading report does not 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.

Benefits to Getting a Diamond Grading Report
Diamond grading reports assure you of the authenticity and quality of your diamond. As most consumers are not diamond experts, a certificate is an objective comparison. In addition, some insurance companies may require a grading report if you are planning to insure the diamond.

Does a Diamond Grading Report Increase the Value of My Diamond?
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. Since each diamond is unique, a certificate will help you identify the special characteristics of your diamond.

How Much Does it Cost? How Long Will it Take?
Depending on the laboratory used in the process for a diamond grading report can vary anywhere from 2 weeks or longer. The fee for a grading report varies depending on the carat weight if your diamond. Many labs charge approximately $75 for the first carat. If your diamond is larger than 1 carat, the price increases incrementally in relationship to carat weight. For exact prices, we suggest you contact specific labs to get price quotes.

Some well-known organizations that provide grading reports include the American Gemological Society (AGS), Diamond High Council (Hoge Raad Voor Diamant; HRD), European Gemological Laboratory (EGL), International Gemological Institute (IGI), and the Gemological Institute of America (GIA), to name a few. Your local jeweler can help aid you in acquiring a grading report through one of these labs either at the time of purchase of after.
