AGS Diamond Grading reports help you to make an informed purchase when choosing a diamond.
The AGS 0-10 grading scale is easy to understand: the highest possible grade is 0, and the lowest is 10. So a diamond with a color grade of 3 has less color than a diamond with a color grade of 5. Diamonds with less color are rarer; therefore, they may cost more. When writing the grades of a diamond using the AGS Scale, the diamonds Cut grade is listed first, followed by the diamonds Color, Clarity, and lastly, Carat Weight.
For example, if a diamond possessing the finest diamond cu grade and is also colorless, free of inclusions and blemishes, and weight one carat, it would be written as: 0/0/0-1.000 carat.
