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.

Couleur

Color intensity, the deepness or richness of color, is the most important consideration when purchasing a colored diamond. Plus la couleur est intense, plus rare et précieux est le diamant.

All of our Blue Nile colored diamonds possess natural color and are never exposed to artificial coloring techniques such as dyeing or irradiation.

Carat

After color grade, carat weight has the most impact on price for colored diamonds. Dans les mines de diamants, l’extraction de grandes pierres est beaucoup moins fréquente que celle des petites. Ceci rend les grands diamants plus précieux. For this reason, diamond prices for colored diamonds rise exponentially with carat weight.

Pureté

Due to the nature of colored diamonds, clarity is less important than it is in their colorless counterparts. En effet, les inclusions tendent à être masquées par la couleur des diamants.

Taille

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.

Forme

Alors que la taille désigne le comportement du diamant à la lumière, ses dimensions et son fini, la forme fait référence à la forme du diamant vu de haut (ex. ronde, princesse ou 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.

Certification

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. Chaque diamant est accompagné d’une identification du diamant coloré, et d’un rapport sur son origine. Ce rapport officiel répertorie les spécifications du diamant, notamment son degré de couleur, et garantit son origine naturelle.

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.
