Clarity

Nature is rarely perfect, so it is very rare to find a diamond that is completely pure and free of inclusions. Inclusions are minerals or crystals trapped within the stone at the time of its formation. Without ten-power magnification, you may never see these tiny inclusions, but they are the fingerprint that makes each diamond unique. Diamond clarity is assigned a value from Flawless to Included 3.
