The clarity grading system is a scale that tells you what type of markings - size, type and location markings, - are in a diamond. The clarity grading scale ranges from flawless to I3, or included 3. Flawless means that there are no visible markings at a 10 power magnification, and included 3 means that there are markings that may be visible to the naked eye.
