Precision – This is pardon? tells you how “clear” a diamond is. Almost every diamonds contain “origin marks”. These origin marks are called “Inclusions” and range of forms of inclusions survive:
Black inclusions
Exterior imperfections
Vapors
Feathers

These imperfections contain a direct effect on diamond value. Depending on the quantity of imperfections and of what type, the diamond be able to be graded as to its clarity, initial from I3 to F. The prices of diamonds go up radically from Included to Flawless.
