Red, green, purple and orange diamonds are generally the rarest, followed by blue and pink. Today, yellow diamonds are thought of as “traditional” and are among the most abundant of all “fancy colored” diamonds. Using highly controlled viewing conditions and color comparisons, a fancy color grader selects one of 27 hues, then describes tone and saturation with terms such as “Fancy Light,” “Fancy Intense” and “Fancy Vivid.” This color system was developed by GIA and is used worldwide. Hue refers to the diamond’s color, tone refers to the color’s lightness or darkness and saturation refers the color’s depth. GIA evaluates color in terms of hue, tone and saturation. Shades that are deep and distinct in color are rated more highly than light or pale shades. They come in pale pinks and blues, bright yellows, oranges, greens, reds and brown colors like cognac and champagne.įancy color diamonds are evaluated by their color intensity, unlike colorless diamonds that are graded on their fire and brilliance. The geological conditions needed to create these colors are rare, making them scarce and highly prized.
