A diamond's clarity is the quality of the diamond relating to the existence and visual appearance of the internal characteristics of the diamond; called inclusions, and surface characteristic called blemishes. Most diamonds are formed in extreme circumstances from primeval carbon deep in the earth's mantle at about 500,000 to 2 million feet below the surface. The extreme heat and pressure that diamonds undergo during their "birth" can cause unique "birthmarks" that affect their clarity.
