Diamond Colour

Buying Tips

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

More Expert Tips

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