When buying a diamond, certification is very important. It is different from being appraised by a jeweler, though every appraisal will have a certification component. Every diamond is of different quality, though many might look the same. A diamond certificate will define the diamond’s attribute. It assure the buyer of the quality she is paying and gives the precise grading of the 4Cs color, clarity, cut and carat weight. The 4Cs together, will define the diamond value.

Certification gives you the information you need to assess a diamond's value compared to other diamonds. It also allows you to make an intelligent comparison with other diamonds either in the same jewelry store or in another.

Diamond certificates are issued by independent gemological laboratories, not your jeweler. There are several grading laboratories, the most prominent being: the International Gemological Institute (IGI); the Gemological Institute of America (GIA); the American Gem Society (AGS); the European Gemological Laboratories (EGL) and GemEx Systems.

When you buy a diamond, be sure to question the sales associate first about the characteristics or attributes of the stone. Ask to see the diamond certification that will accompany the diamond when you purchase it. If you do some comparison shopping, you will note that the quality of the diamonds each jeweler carries varies depending on the store.

A diamond certification will also give you indicators about other diamond qualities, such as fire, brilliance and scintillation, also called Return of Light. These qualities refer to how light is refracted back to the viewer when held stationary or when in motion. The certification will also give you a measure of the stones fluorescence. These factors also impact the beauty and brilliance of your diamond.
