About Diamonds > Colour

Diamonds are found in varying shades of white, which range from a totally colourless stone to a light tint of brown or yellow.

Diamonds are graded on a very subtle colour scale established by the Gemological Institute of America, ranging from D (colourless), at the top of the scale, down to Z.

To the untrained eye a diamond needs to be K or lower before it appears less than white. (If a diamond is graded A, B or C quality this will be a jeweller’s own description and should not be confused with the G.I.A. system).

A very special type of diamond is found on rare occasions, in a ‘fancy’ colour; pink, blue, green, yellow, brown, orange or – very rarely – red. These are so unusual that they are extremely valuable and treasured by collectors around the world.
