Diamond clarity A diamond should shine bright and have an inner fire that is worthy of the world’s most precious gemstones. Diamond clarity refers to the amount of inclusions and blemishes a stone has that detract from its value. A diamond is ”loupe clean” or “internally flawless” if, after examination by an experienced grader with a loupe 10 x under normal light conditions, it has been found free of internal characteristics. The other clarity grades are determined by the size, position, brightness and number of internal characteristics. External characteristics and structure phenomena can be mentioned under ”identification marks” or ”comments”. The lowest clarity grades on the scale (indicated by p for piqué) refer to inclusions that can be seen by an experienced grader with the naked eye.
