The clarity grade is based on the presence or absence of inclusions produced by nature.
While no diamond is perfectly pure, the soul of a diamond is its clarity. Deep within the diamond lies the presence of natural characteristics known as blemishes or inclusions. These defining characteristics are natural imperfections crafted by mother earth many years ago. Inclusions are the diamond’s fingerprints, no two diamonds are alike. Diamonds with fewer inclusions/blemishes receive a higher clarity grade while diamonds with a higher presence of inclusions/blemishes receive a lower clarity grade.
