At Blue Nile, you'll find color grades that range from K (faintly colored) to D (colorless). Lower color grades exist, but L–Z color grade diamonds aren't available at Blue Nile.
Diamonds with a D color grade are absolutely colorless and the rarest of all color grades.
Color, cut, clarity, and carat—the 4Cs—all affect a diamond's price. A D-color diamond will cost much more than a K-color diamond. When working within a budget, try prioritizing cut over color to maximize brilliance.
The larger the diamond, the easier you'll notice the color. For this reason, we recommend shopping for an H color grade or higher if your diamond is one carat or larger.
