The 4Cs

How GIA Grades Your Diamond

Every diamond is unique, yet all diamonds share features that allow them to be compared and evaluated. These are the 4Cs: color, clarity, cut, and carat weight.

Diamond color

Color

The GIA Color Scale extends from D, colorless, to Z, light yellow or brown. Truly colorless diamonds are rare, while most diamonds used in jewelry are nearly colorless.

Diamond clarity

Clarity

The GIA Clarity Scale includes eleven grades ranging from Flawless to I3. These characteristics help gemologists evaluate and identify individual stones.

Diamond cut

Cut

The GIA Cut Scale ranges from Excellent to Poor. Cut influences brightness, fire, scintillation, and the overall sparkle you see when the diamond moves.

Diamond carat weight

Carat Weight

One carat equals 200 milligrams. For diamonds under one carat, each carat is divided into 100 points, similar to pennies in a dollar.

0.75 ct. = 75 points
0.50 ct. = 50 points
