Colour 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.

Diamond Colour Grade List

Diamonds listed below are the qualities available at Purely Diamonds

D Colour (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.

E Colour (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.

F Colour (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.

G Colour (Near Colourless)

The highest of the ‘near colourless’ grades, G colour diamonds have a slight colour difference but only if compared side by side to grades D or E. G colour appears colourless once set so is excellent value for money.

H Colour (Near Colourless)

The second highest of the ‘near colourless’ grades, H colour diamonds still appear colourless unless directly compared with higher grades. H colour is a popular choice as it appears white once set, and is the best value for money.
