Diamond Color

Key Points

  • Of the 4Cs, color is the second most important characteristic because the human eye detects sparkle first (diamond cut) and color second.
  • As a diamond's color grade improves, it's price increases. However, at a certain point, the color difference cannot be detected unless under professional magnification.
  • To maximize your budget, choose what's called a near-colorless diamond (grades G-H) because the naked eye will still not see traces of color for these grades.

Color manifests itself in a diamond as a pale yellow. This is why a diamond's color grade is based on its lack of color. Blue Nile offers only Colorless (grades D-F) to Near-Colorless (grades G-H) diamonds to assure that any natural color present is typically undetectable to the unaided eye.

Expert Buying 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.
