Although the method for determining the clarity of a natural colored diamond is identical to that of a colorless diamond, clarity is less important in determining the value of a natural color diamond.

Same as with colorless diamonds, clarity is the measure of the lack of blemishes and the overall flawlessness of a diamond. Although no diamond is 100% pure, the closer it comes to flawless on the GIA clarity scale, the higher its value.

Because diamonds are a natural occurrence, they contain many characteristics that are the result of the extreme heat and pressure that created them. These unique internal characteristics which are called ‘inclusions’ are evaluated along with any external characteristics (blemishes) to determine the true clarity of a diamond. Diamond clarity is judged at a 10x magnification, and even a diamond that has been classified as flawless may have inclusions at higher magnifications.

In order to evaluate the clarity of a diamond, a gemologist reviews the number, size, relief, nature, and position of the inclusions and blemishes to determine where it falls on the GIA International Diamond Grading System. The diamond is then assigned a clarity grade that ranges from flawless (FL) to diamonds with obvious inclusions (I3).

Most of these characteristics are too small to be seen by the naked eye, but still factor into the price. However, clarity has no effect on the overall performance of the diamond’s ability to reflect light, unless the clarity is heavily included.
