FANCY COLORED DIAMONDS
Fancy color diamonds are formed through a unique combination of chemical composition and external elements, along with how light interacts with the diamond’s internal structure. These rare and valuable gems owe their vivid hues to specific geological conditions present during their formation.
Unlike traditional white diamonds, which are prized for their brilliance, fancy color diamonds are evaluated primarily based on the intensity and purity of their color. The deeper and more vibrant the hue, the more valuable the diamond.
Fancy color diamonds span a stunning spectrum of shades, including yellow, pink, red, blue, green, purple, and black. Some diamonds display pure, vivid colors, while others feature blended tones, such as greenish yellow or reddish brown, adding to their uniqueness.
The Gemological Institute of America (GIA) classifies fancy color diamonds into nine distinct color intensity categories, offering a detailed framework for assessing their beauty and rarity.

Key takeaway
The rarity and price typically increase as you move from left to right, with Fancy Vivid being the most valuable, especially in popular colors like pink, blue, and yellow.
