Target units such as at least one-hundredth of a carat (0.01 carat or 2 mg) are usually only used for diamonds weighing one carat.

Clarity can also be a measure of a diamond's internal imperfections called inclusions. Inclusions are also small cracks that appear pale or cloudy or structural defects such as crystals or other diamond crystals in the rim material. The number, size, color, relative position, orientation and visibility of inclusions can affect the relative transparency of a diamond.
