With a diamond certificate, you will be able to verify the color, cut, carat, weight, and clarity of the diamond. You may be required to pay for the certificate and in many cases, you will be able to negotiate a better price on the diamond. If you have a high quality diamond and decide to sell the diamond, you will require the certificate, otherwise it will be hard for selling it to someone else.
Furthermore, you can use the Diamond Grading Report to look up the wholesale value of the diamond in question. With the Certificate, or Diamond Grading Report, there won't be any doubts when you are trying to purchase a diamond. You can easily find out what the diamond is worth. This will prevent you from overpaying, and it can prevent a seller from under-charging as well.
