L colour: L-colour diamonds are considered to be in the "near colourless" range. This means that while there may be a slight tint of colour, it's typically not very noticeable to the naked eye, especially when viewed in isolation.

K colour: The first of the "faint" colour grades, meaning colour may be detectable to the naked eye. K-colour diamonds can offer great value.

J colour: The last of the "near-colourless" grades, colour may be slightly detectable to unaided eye, particularly in fancy shapes/diamonds over 1-carat.

I colour: Colour may be only slightly detectable upon close examination. Exceptional value.

H colour: This is considered within the "near-colourless" range. Colour is only noticeable when compared to much higher Color grades. Excellent value.

G colour: The highest "near-colourless" grade. Colour may be detectable when compared to much higher "colourless" grades. Excellent value.

F colour: A "colourless" grade appreciated best set in platinum or white gold. Faint colour detectable by a trained gemologist.

E colour: A "colourless" grade appreciated best set in platinum or white gold. Traces of colour difficult for even trained eye to detect.

D colour: Highest, absolutely "colourless" grade, appreciated best set in platinum or white gold. Exceptionally rare.
