Bright white light...

Colour is a decisive aspect when judging the beauty of a diamond. The purer and more colourless the diamond, the greater its rarity and value. Not only this, but its capacity to reflect and refract light ensuring you have a glistening diamond forever. White diamonds come in various shades and may appear colourless to the untrained eye, however on closer inspection they will almost certainly contain very slight traces of brown, yellow or grey. Diamonds are graded on a colour scale established by the Gemmological Institute of America (GIA). This scale ranges from D (colourless) and moves through the alphabet to Z. The price difference even between a single colour grade can be significant.

Coloured diamonds include blues, pinks, greens, browns, oranges and, very rarely, reds.

GIA Colour Grades:

  • (D-F) Colourless tint nearly undetectable to an unaided, trained eye even when compared to white standard.
  • (G-H) Near Colourless tint almost undetectable to the trained eye, but apparent when compared to white standard.
  • (I-J) Near Colourless trace of tint just detectable to the trained eye, but noticeably apparent when compared to white standard.
  • (K-M) Faint Yellow to Faint Brown tint apparent to the trained eye and readily apparent when compared to white standard.
  • (N-R) Very Light Yellow to Very Light Brown tint is easily apparent to the unaided, trained eye.
  • (S-Z) Light Yellow to Light Brown tint, is obvious to the unaided, trained eye.
