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.
One of the good things about IGI certification is they are cheap and processed faster. But when compared to GIA diamond certifications, IGI is a bit inconsistent.
