How To Read A Diamond Grading Report?

A diamond grading report, also known as a diamond certificate, provides detailed information about the characteristics of a diamond. Here’s how to read a diamond grading report:

  1. Diamond shape and cutting style: This refers to the overall shape of the diamond, such as round, princess, emerald, or cushion, and the cutting style, which refers to the way the diamond is cut and the number of facets it has. Different shapes and cutting styles can affect the diamond’s brilliance, fire, and overall appearance.

  2. Carat weight: This is a measure of the diamond’s weight and is often used to determine its overall size. One carat is equivalent to 0.2 grams, and larger diamonds are generally more valuable than smaller ones.

  3. Color grade: This refers to the presence or absence of color in the diamond. The Gemological Institute of America (GIA) grades diamonds on a scale from D (colorless) to Z (light yellow or brown). The less color a diamond has, the more valuable it is.

  4. Clarity grade: This refers to the presence or absence of internal and external blemishes or inclusions in the diamond. The GIA grades diamonds on a scale from Flawless (no blemishes or inclusions visible under 10x magnification) to Included (blemishes and inclusions visible to the naked eye).

  5. Cut grade: This refers to the quality of the diamond’s cut, including the symmetry and proportions of the diamond. A well-cut diamond will have better brilliance, fire, and overall appearance than a poorly cut diamond.

  6. Fluorescence: This refers to the diamond’s reaction to ultraviolet light. Some diamonds may exhibit fluorescence, which can affect their color and overall appearance.


Reading a diamond grading report can be helpful in understanding the characteristics of a diamond and determining its overall quality and value. It’s important to note that each of these factors can influence a diamond’s price, and it’s up to the individual to determine what combination of factors is most important to them.
