The colour of a lab diamond ring is graded on a scale from D to Z, with D being the most colourless and Z being the most coloured. The colour of a lab diamond is determined by the presence of impurities, such as nitrogen or boron. The less impurities a diamond has, the more colourless it will be.

  • G-J: Near colourless. These diamonds have a very slight yellow or brown tint, but it is not visible to the naked eye.
  • K-M: Faint yellow or brown. These diamonds have a noticeable yellow or brown tint, but it is not considered to be a major flaw.
  • N-R: Very light yellow or brown. These diamonds have a strong yellow or brown tint, and it is considered to be a major flaw.
  • S-Z: Light yellow or brown. These diamonds have a very strong yellow or brown tint, and it is considered to be a major flaw.

For example, a diamond set in white gold will appear more colourless than a diamond set in yellow gold.
