The grading of a gemstone based on the presence or absence of inclusions. The less inclusions, the better a gemstones clarity grade. In diamond grading clarity is one of the four C's (cut, color, clarity, carat weight) and is divided in defined grading terms which can be found in the table below. Colored stones don't have such a defined grading system but you will find gemstone dealers using similar descriptions for colored stones.
