The Fifth C: Certificates

A certificate is a way of identifying a diamond; it shows the diamond's exact measurements and includes the details of the 4 C’s. It precisely points out all the individual characteristics of the diamond. It also identifies the shape of the diamond, including: Round Brilliant, Cushion, Princess, Emerald, Radiant, Oval, Pear, Marquise, Asscher and Heart shapes.

A certificate is not the same thing as an appraisal. A certificate describes the quality of a diamond, but it does not place a monetary value on the gem. An appraisal places a monetary value on your diamond, but does not certify the quality of the diamond.

There are many diamond laboratories that issue certificates, but the Gemological Institute of America (GIA) is recognized as the standard for diamond grading labs in the world.

The different laboratories have different grading standards, and some laboratories will be more lenient with their standards than others.
