Natural diamonds can also come in a variety of vivid colors including yellow, pink, blue, green, red, orange, and black. Fancy colors are evaluated in several ways. The first quality is the basic hue or color (the rarer the color, the greater the cost) of the diamond. The second is the stone’s intensity (the richness or saturation of the color). The third is the purity of the color (is the color is bright and clear or clouded). These color characteristics form the basis for determining a fancy colored diamond’s worth. The more intense the color, the rarer, and more expensive the diamond. For example, a fancy light yellow diamond costs less than a fancy vivid yellow diamond of equal size, shape, and clarity.
