Only one in every 10,000 diamonds possesses natural color and is referred to as a colored diamond. For this reason, colored diamonds are purchased almost exclusively for the intensity and distribution of the diamond's color. Criteria considered when purchasing a white or colorless diamond, such as cut proportions and clarity, are less important when purchasing a colored diamond.
The information below will help you understand colored diamonds to determine the diamond that's right for you.
Color intensity, the deepness or richness of color, is the most important consideration when purchasing a colored diamond. The more intense the color, the rarer and more valuable the diamond will be.
All of our Blue Nile colored diamonds possess natural color and are never exposed to artificial coloring techniques such as dyeing or irradiation.
After color grade, carat weight has the most impact on price for colored diamonds. When diamonds are mined, large gems are discovered much less frequently than small ones. This makes large diamonds much more valuable. For this reason, diamond prices for colored diamonds rise exponentially with carat weight. Learn more about carat weight in our Diamond Education section.
Due to the nature of colored diamonds, clarity is less important than it is in their colorless counterparts. This is true because inclusions tend to be masked by the diamond's color.
Colored diamonds are primarily cut to emphasize their color. This contrasts with colorless diamonds that are cut to maximize sparkle or brilliance, which in some instances can detract from the natural color of a colored diamond. While colored diamonds still exhibit brilliance, color is the most important characteristic considered when they are being cut.
While cut describes a diamond's light performance, dimensions and finish; shape refers to the overall outline of the diamond when viewed from the top (e.g. round, princess or marquise). It's important to note that many colored diamonds are cut into non-traditional shapes to enhance their natural color. Due to the rarity of colored diamonds, a specific shape in a specific color may not be available at any given time.

All Blue Nile colored diamonds are independently analyzed and graded by the Gemological Institute of America (GIA), which is among the most respected laboratories in the diamond industry. Each diamond is accompanied by a colored diamond identification and origin report. This authoritative report lists the diamond's specifications including its color grade, and ensures its natural origin.
Setting Colored Diamonds
When choosing a setting for a colored diamond, it is best to choose a setting material that will enhance the natural color of your diamond. For example, yellow diamonds are often set in yellow gold, while pink diamonds look best when set in rose gold.
