Saturation Scale

Use the GIA saturation scale to judge a gem's strength of color. In warm colors, weaker saturations of 1, 2, or 3 appear brownish. In cool colors the same values look grayish. In both warm and cool colors, gems with saturations of 4, 5, or 6 are almost always more valuable if all other factors are equal.
