A diamond certificate will not place a dollar value on your diamond. Instead, the certification will describe the stones key quality characteristics which affect its value the most. It grades each of the 4Cs and then lists results for any process carried out on the stone, such as laser drilling, fracture filling, irradiation, and HPHT treatment, which may have been performed earlier on the diamond and has affected its quality. A diamond certificate can also be useful if you want to get your ring or jewelry appraised for insurance purpose.
You can get your diamond certified by sending it to a gemological laboratory which will analyze and grade the stone according to their specifications and then give you a certificate, which is also known as adiamond grading report.
