- The clarity and cut of a diamond are two of the four C's of diamond grading. (The other two are color and carat.) For a sample of diamonds, the accompanying table lists the clarity (related as internally flawless, IF, very very slightly included, VVS, very slightly included, VS, slightly included, Sl and included, I) for the two lowest ratings for cut, which are "good" and "fair". Complete parts a through c below. E Click the icon to view the table a.
