Colour

The finest white diamonds are as close to colourless as possible. Colourless diamonds are graded on a scale from D–Z.  A ‘D’ grade is totally without colour, whilst ‘Z’ signifies a diamond containing a hue of light yellow.

At first glance, the difference between one grade and the next appears minimal: until careful comparison by a professional’s eye shows increasing shades of colour, reducing the stone’s value.

The vast majority of diamonds bearing the Graff name are of scale D-G, signifying both their beauty and their rarity.
