The GIA’s color grading system is based on three main attributes: hue,toneandsaturation.Hue refers to the diamond's characteristic color, tone refers to the color's relative lightness or darkness, and saturation refers the color's depth or strength. The general rule of thumb is that the stronger the hue, the more valuable the stone. However, the grades are based on the overall combined effects of the diamond’s hue,tone and saturation. GIA uses nine grades to distinguish color saturation. These are: FancyVivid (themosthighlysaturated),FancyIntense,FancyDeep, Fancy Dark,Fancy,Fancy Light,Light,Very Light and Faint. Sometimes a diamond can possess more than one hue. In such cases, the dominant color is always described last. For instance, a Fancy Purplish Pink diamond is in fact a pink diamond.
