Diamond Colour: Diamond is the only gemstone prized for its lack of colour. While many diamonds appear colourless, subtle differences exist, and diamonds may have subtle yellow or brown tones. A tint of yellow or brown in a diamond is due to nitrogen trapped inside. How close a diamond is to colourless determines its value, so the less colour a diamond has, the more valuable it is.
Unless you are a diamond expert you will probably not be able to tell the difference between diamonds which are colour graded D to I unless you are comparing diamonds side by side. At Cliveden Jewellers, we believe in providing our customers with only the highest quality diamonds available on the market today therefore, we only carry diamonds in the colourless to near colourless range.
In a effort to eliminate confusion related to diamond colour, the Gemological Institute of America (GIA) implemented the colour grading system in the 1950s which is still being used industry wide today. Diamonds are graded on a scale beginning with the letter D (colourless) and ending with Z (light yellow or brown).
