IGI Diamond grading system

IGI grades diamonds based on the following criteria like Diamond Clarity, Carat, Cut, Color, and Finish.

Diamond Color is graded on a scale from D to Z where D means Colorless and Z means yellow. Along with this, diamond’s fluorescence is also graded.

Diamond clarity is usually examined by experts using 10X magnification and the diamond’s carat is measured carefully. Apart from this, they also focus on the diamond’s symmetry and proportions.
