Yellow - cooler
Yellow diamonds occur in some of the highest levels of saturation of any coloured diamond. “Cooler” yellows sit toward the yellow/greenish-yellow hue boundary.
Unlike many of the other colour charts, which start with Faint, Very Light, and/or Light, yellow diamond colour grades begin with Fancy Light. This is because paler yellow diamonds are part of GIA’s D-to-Z colour scale which is used to categorise white diamonds.
The shaded areas, where no diamonds are illustrated, indicate areas in the yellow hue range in which diamonds are described as predominantly brown.
