Natural Colored Diamonds

Natural fancy color diamonds are exceptionally rare and prized for the intensity, richness, and distribution of their color. Unlike colorless diamonds, where the absence of color is valued, fancy color diamonds are celebrated for their unique hues and individuality. While cut and clarity still contribute to overall beauty, color is often the most important factor when evaluating these extraordinary diamonds.

Color intensity, richness, and distribution are the most important factors when evaluating a fancy color diamond. In general, the more vivid and saturated the color, the more rare the diamond becomes. All Blue Nile fancy color diamonds display natural color and are not treated with artificial coloring processes such as dyeing or irradiation.

Carat

 

After color intensity, carat weight is one of the most important factors influencing the rarity and price of fancy color diamonds. Larger natural fancy color diamonds are exceptionally uncommon, making size and vivid color together especially rare and sought after. 

Clarity

 

Colored diamonds place less emphasis on clarity, as inclusions are often masked by the presence of color.

Cut

 

Colored diamonds are cut to emphasize color, unlike colorless diamonds, which are cut to maximize brilliance. While they still exhibit sparkle, preserving depth and intensity of color is the primary focus in how they are shaped.

Shape

 

Cut describes a diamond’s light performance, dimensions, and finish, while shape refers to its overall outline (e.g., round, princess, marquise). Many colored diamonds are cut into non-traditional shapes to enhance their color, and, due to their rarity, specific shape and color combinations may not always be available.

Certification

 

All Blue Nile colored diamonds are independently graded by the Gemological Institute of America (GIA) or the International Gemological Institute (IGI), two of the industry’s most trusted authorities. Each diamond includes a Colored Diamond Identification and Origin Report, detailing its specifications—such as color grade—and confirming its natural origin.

Setting Colored Diamonds

 

The way a colored diamond is set influences how its color is perceived. Metal tones can complement or contrast with the stone, while two-tone settings create added balance—bringing the diamond and setting together as a cohesive, intentional composition.
