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 most 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 nor 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 imperfections, the rarer and more valuable the diamond. Many inclusions are not discernable to the naked eye and require magnification to become apparent. A laboratory-certified clarity rating of SI2 represents the point at which inclusions are technically not apparent to the average naked eye.
