Diamond Color

Buying Tips

  • The second most important of the 4Cs is color because it’s what the eye notices next after sparkle.
  • A diamond's color actually refers to its lack of color. The less color, the higher the color grade.
  • To avoid a pale yellow color, choose a diamond grade H or higher.
  • Blue Nile offers only Colorless (grades D-F) to Near-Colorless (grades G-J) diamonds to assure that any natural color present is typically undetectable to the naked eye.

More Expert Tips

  • For the purist, look for a Colorless grade of D-F for a diamond with no discernible color under magnification.
  • For the best value, choose a Near-Colorless grade of G-J for a diamond with no discernible color by the naked eye.
  • Consider platinum or white gold settings when buying higher color grade diamond; a gold setting may show through a colorless diamond.
