Coloured diamonds are coloured because of the inclusion of some other trace mineral -- nitrogen = yellow; boron = blue -- or because of deformation or distortion of the carbon lattice = pink.
Diamonds with little or no trace of other mineral -- other than carbon, which forms the diamond -- or no deformation/ distortion are called 'colourless' or white diamonds.

What is the colour of diamond?
Diamonds can range in color from clear to red and even blue. Most commonly, diamonds are colourless.
What is J diamond grading?
If J is a description of the colour of a white diamond, that grade is given to the near colourless diamonds. You can learn more about this grade from the chart, below, which shows you the full colour range of 'colourless diamonds' from D to Z.
What is a diamond pure of?
A diamond is made of carbon. Some diamonds include colour. For example, the famous Hope Diamond looks blue, because the stone includes traces of boron. Colourless diamonds are pure carbon.
Are diamonds colorless?
Not all diamonds are colorless. Diamonds can come in various colors such as yellow, brown, pink, blue, and black, among others. The most valuable and sought-after diamonds are those that are colorless or display a vivid and intense color.
What does letter H for a diamond stone mean?
On the colour grade for diamonds, H is commonly called 'near colourless'. (Colourless stones are graded D, E and F.)
What are common colors of the diamond?

Are pink diamonds or yellow diamonds more expensive?
Natural pink diamonds are more rare than natural yellow diamonds, probably because the common trace element nitrogen is responsible for a yellow cast in a diamond. Some colourless or 'white' diamonds are considered yellow, when graded with a colour grade from I to Z, as below. Natural pink diamonds exist 'due to structural anomalies" according to Wikipedia, and are very rare. Some diamonds can be altered (or enhanced) to appear yellow or pink, and when altered, are less valuable than naturally colored diamonds.
How many colors of diamonds exist?
The exact number is infinite, but a finite number exists in terms of colour grades. For 'white' or 'colourless' diamonds, the grades begin with the letter D -- colourless -- and trail off to the letter Z -- light colour, with five broad categories of grades. For coloured diamonds, please review the Color Grading system, also linked below, to identify the hue, tone and saturation variables available for grading coloured diamonds. Can you do the math?
What is the color of the diamond stone?
Raw diamonds come in all the colours imaginable -- from 'white' or 'colourless' -- which has its own range of colours, to diamonds in all the colours and intensity of colour, of the rainbow. You can read more, below.
Does the composition of a diamond have any affect on its cost?
Yes. While all diamonds are carbon, some diamonds are called coloured diamonds, because they contain traces of other minerals. For example, the Hope Diamond appears blue because it contains traces of boron. Fancy coloured diamond stones are usually more expensive that comparable 'colourless' stones.
