Diamond studsColour of a diamond
A diamond can divide light in to a spectrum of colours (like a prism). Colour in a diamond acts like a filter and diminishes the spectrum of colours emitted.
The less colour in the diamond, the better the colour grade.
Grades of colour range from D, which is totally colourless, to Z, which is a pale yellow or brown colour.
Diamonds that are ‘colourless’ (graded D, E or F) are very rare and demand premium prices. The untrained eye will find it very difficult to distinguish between D, E or F grades.
G, H, I and J are ‘near colourless’ and represent excellent value for money. G and H are sometimes called ‘rare white’ and are the most sought after in the ‘near colourless’ group.;

Grade List
Diamond colour grade D (Colourless)
The highest colour grade a diamond can have, meaning the stone is completely colourless. D colour diamonds are extremely rare and therefore command the highest prices.
Diamond colour grade E (Colourless)
The second highest colour grade a diamond can have. Classed as colourless, E colour diamonds will have only the most minute traces of colour that can be detected only by an expert gemmologist.
Diamond colour grade F (Colourless)
The least expensive of the premium 'colourless' diamonds (D, E & F). F colour diamonds are classed as colourless as the traces of colour can only be detected by an expert gemmologist.
Diamond colour grade G (Near-Colourless)
The highest of the 'near colourless' grades, G colour diamonds have a slight colour difference but only if compared to grades of D, or possibly E, side by side. Even then, to the untrained eye most will not see the difference in colour. G colour diamonds appear colourless especially once set, so they are excellent value for money.
Diamond colour grade H (Near-Colourless)
