Diamond Info: Colour

Colour refers to the degree to which a diamond appears colourless. Diamonds are graded on a colour scale established by the Gemmological Institute of America (GIA) which ranges from D (colourless) to Z (strong yellow or brown).

Diamonds which have tinges of yellow are more common than colourless diamonds and as such are less valuable than colourless diamonds.

Completely colourless diamonds are graded "D/E/F" and are treasured for their rarity. As such they are extremely valuable. Please roll-over the colour scale below for more info:
