Diamond Attributes – Clarity

Did you know what characteristics determine the value of a diamond? They are the Cut, Color, Clarity, Carat Weight, and Shape. This article will focus on the clarity of a diamond.


Because of their unique optical properties, diamonds, more than any other gemstone, are capable of producing the maximum amount of brilliance. While minute crystals of diamond or other minerals are contained in almost all diamonds, a diamond that is virtually free of inclusions and surface markings will be judged as flawless. In these diamonds nothing interferes with the passage of light or spoils the beauty, but these diamonds are extremely rare and will command a high price.

To determine a diamond’s clarity grading, it must be examined under a 10x magnification by a trained, skilled eye. What minute inclusions there may be make every diamond unique. These are, in fact, nature’s fingerprints and do not mar the diamond’s beauty nor endanger its durability. Without high magnification, you may never see these inclusions. However, the fewer there are, the more rare your diamond will be.

The following chart will show you the different levels of clarity.
