Dazzling brilliance. Captivating color. The planet’s most valued gems are fancy color diamonds.

ABOUT FANCY COLOR DIAMOND

Gem diamonds in GIA’s D-to-Z range usually decrease in value as the color becomes more obvious. Just the opposite happens with fancy color diamonds: Their value generally increases with the strength and purity of the color. Large, vivid fancy color diamonds are extremely rare and very valuable. However, many fancy diamond colors are muted rather than pure and strong.
