Fancy Colored Diamonds

Yellow and brown diamonds that fall outside of the D through Z color range, as well as diamonds of other colors, such as blue, pink or green, are categorized as colored diamonds or, "Fancy Colors."

While the vast majority of diamonds fall in the D-to-Z color range, nature occasionally produces diamonds with a naturally occurring blue, brown, pink, deep yellow or even green hue. The geological conditions required to yield these colors are rare, making diamonds with distinct and naturally occurring shades scarce and highly prized.


Unlike colorless and near-colorless diamonds, fancy-color diamonds are evaluated less for brilliance or fire and more, for color intensity. Shades that are deep and distinct are rated higher than weak or pale shades.

Gemological laboratories describe fancy color diamonds in terms of hue, tone and saturation. Hue refers to the diamond's characteristic color; tone refers to the color's relative lightness or darkness; and saturation refers to the color's depth or strength. Using highly controlled viewing conditions and color comparators, 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."

The grading of colored diamonds is conducted utilizing comparison masters diamonds, and a nine-tiered rating system for color, ranges from Faint to Fancy Vivid, is employed. Among the most famous colored diamonds are the Hope, a 45.52-carat blue diamond at the Smithsonian Institution, and the 41-carat Dresden Green Diamond, both fabled in their cultural history.

Fancy colored diamonds combine the sparkle and brilliance of a colorless diamond with the alluring hues of colored gemstones like rubies, emeralds, and sapphires. Naturally occurring colored diamonds are very rare and therefore, command top prices.

Historically, celebrities, royalty, and other aristocrats have owned and worn these unique gemstones, but times are changing. These rare gifts from nature are rapidly gaining popularity among today's jewelry lovers as well.

Celebrity fascination with fancy colors accounts for at least some of the sudden spiral in popularity. Whoopi Goldberg wore yellow diamonds to the 1999 Academy Awards. Heather Locklear wore pink diamonds to the 2000 Golden Globes, and, Academy Awards presenter, Salma Hayek, wore a 6.17-carat, fancy-intense pink diamond ring. Actress Julianne Moore wore a 7.52-carat, fancy-vivid yellow diamond.
