What is a Diamond Certificate?

A diamond certificate, also known as a diamond report, is issued by an accredited independent gemological laboratory. In addition to the diamond’s carat weight and measurements, a certificate includes grades for the diamond’s cut, color and clarity. These grades are the opinion of the individual at the lab who graded the diamond, based on the lab’s own subjective grading standards. Certificates also include other information about the diamond’s polish, symmetry and fluorescence, and also a graphical depiction of the diamond showing the location of the diamond’s inclusions.

4Cs of the Diamond

Carat

Or the weight /size of a diamond. A carat is made of 100 cents so a 50 cent diamond is also a 0.5-carat diamond. The larger the size of the diamond the more desirable it is. But even a 1-carat diamond would be lifeless without the right cut and color. So the caratage of a diamond shouldn’t be given undue importance. We provide you withDiamond Certification.
