Diamonds, unlike other gemstones, have the ability to produce the maximum amount of brilliance. A diamond that is free of exterior and interior inclusions is of the highest quality because inclusions do not interfere with the light passing though the diamond. To determine a diamond's clarity, it is viewed under a 10x magnification by a trained eye.

Inclusions in a diamond are natural and considered to be nature's fingerprints on the stone. The minute inclusions neither mar its beauty nor endanger its durability.

The ability to accurately assign a clarity grade to a diamond is very difficult. Because of this, international grades have been established.
