Certification
Diamond certificates are more accurately known as Diamond Grading Reports. These documents are commonly provided with the purchase of a significant stone of over 25 points or more. These reports are prepared by independent, certified gemmologists from laboratories around the world and can help calculate the specific characteristics of your diamonds (colour, cut, clarity and carat weight, for example).
This process is only undertaken for known jewellers and normally these labs won't deal with the public.
A diamond grading report will commonly, but not always, include a plotted diagram of your diamond and all significant characteristics, including the 4C's (cut, colour, clarity, carat weight). The report can also describe the diamond's shape, exact measurements, proportions and depth percentages as well as grade the polish and symmetry. It could also comment on the characteristics like fluorescence, graining, and any imperfections in the diamond. Please note that a grading report does not include an appraisal or any kind of statement of monetary worth of the diamond. Grading reports simply state scientific facts and reputable opinions of your diamond that can be evaluated by highly standardised criteria. The best way to understand your diamond grading report is to schedule an appointment with your jeweller. This way, he can explain to you each portion of the certificate while visually examining your diamond with you.
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. It is important for all consumers to be aware that a lot of diamond grading is and only ever will be an opinion, be it someone with 20 years experience or the average of three people's opinions. As happens plenty of times over, a diamond can be submitted back to a lab where previously it has received an E - VS2, and return this time with an F SI1. Some insurance may require a grading report if you are planning to insure the diamond. But most will only need a valuation.
Certification of a diamond does not increase the value of your diamond. Certification is however 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.
The fee for a grading report varies depending upon the carat weight of your diamond. For exact prices, we suggest you contact specific labs to get quotes.
