What are the 4Cs of a diamond? How do you make a decision on what you want in a diamond, especially when it comes to diamond grading?

Learn about the different grades on an AGS Labs’ diamond grading report, and walk away with a better understanding of what gives a diamond its beauty and quality. 


Of all the 4Cs, cut has the greatest effect on a diamond’s beauty. In determining the quality of the cut, the grader evaluates the cutter’s skill in the fashioning of the diamond; technology. The more precise the cut, the more captivating the diamond is to the eye. Here you can see several of the different cut styles that diamonds come in.


Gem-quality diamonds occur in many hues. In the range from colorless to light yellow or light brown. Colorless diamonds are the rarest. Other natural colors (Blue, Red, Pink for example) are known as fancy – their color grading is different than from white diamonds. Learn about colored diamonds trends


Diamonds can have internal characteristics known as inclusions or external characteristics known as blemishes. Diamonds without inclusions or blemishes are rare; however, most characteristics can only be seen with magnification. Learn more about diamond clarity and how it is determined


The carat is the diamond’s physical weight measured in metric carats. One carat equals 1/5 gram and is subdivided into 100 points. Carat weight is the most objective of the 4Cs. It involves no estimates, comparisons or judgments.
