Diamond certification


A Diamond Grading Report issued by an Independent Gemological Laboratory, tells you that the Diamond has been examined by experienced Diamond Graders, using various gemological instruments, and contains the characteristics as stated in the Certificate.

The reason it is important to have a Diamond evaluated by an independent Laboratory is that minute, invisible to the naked-eye, characteristics of a Diamond can have a major influence on the price. Therefore, if not for a great deal of scrutiny on the part of the buyer, it is easy to mistake and purchase a Diamond of lower value, believing it to be of higher value.

Here at World Diamond bourse we understand the importance of the Diamond certificate, not only is it your guarantee as to the exact specifications of your stones, it also enables you to make direct comparisons between like for like stones, and by price and quality. Thereby ensureing that you get the best value for your money.
