Colour

In diamonds the colour refers to the lack of colour. While many diamonds appear colourless, or white, they may actually have subtle yellow or brown tones that can be detected when comparing diamonds side by side. Diamonds are graded on a colour scale established by the Gemological Institute of America (GIA) which ranges from D (colourless) to Z.

Truly colourless stones, graded D, are rare and very valuable. The closer a diamond is to being colourless, the rarer and more valuable it is. By international grading standards, the colour H is considered to be the base white, anything less is considered to be tinted colour. Coloured diamonds such as Pink, Blue, Cognac and Champagne do not follow this grading chart.
