Strength of Color
Natural color diamonds can vary in color saturation or strength from very faint to an intense vivid color. Just a slight shift in color strength can make a colored diamond affordable. The strength of color is one of the most important factors in determining the value of a natural colored diamond. The value increases with the intensity of the most prominent color within the diamond.
In an attempt to bring some uniformity to the industry description of natural color diamonds, gem analysis laboratories have developed the fancy colored diamond color scale to classify the strength or intensity of a diamond's color. Generally speaking, such gradient scales and tools are a reflection of human attempt to categorize the color the eye sees and judge it within three parametric areas: Color Hue, Tone and Saturation.
