Diamond Colour

Diamond colour refers to the natural tint present in a stone, graded from colourless to light yellow or brown, with colourless diamonds considered the most rare and valuable.

While a diamond can split light into a rainbow of colours, any natural tint acts like a filter and reduces this effect. The less colour present, the higher the grade – and the more brilliantly the diamond will appear.

The colour scale runs from D (completely colourless) to Z (noticeably tinted). Diamonds graded D, E, or F are exceptionally rare and command premium prices, though to the untrained eye the difference between them is almost impossible to spot.

Near-colourless grades G to J offer excellent value, with G and H often called ‘rare white’ – a highly sought-after balance of beauty and price.

Diamond Colour Grade List

Diamonds listed below are the qualities available at Purely Diamonds

D Colour (Colourless)

The highest colour grade a diamond can receive. D colour diamonds are completely colourless, exceptionally rare, and therefore command the highest prices.

E Colour (Colourless)

The second-highest grade, E colour diamonds are classed as colourless. Any trace of colour is so minimal it can only be detected by an expert under close examination.

F Colour (Colourless)

The most affordable of the premium colourless grades (D, E, F). F colour diamonds are still considered colourless, with only very slight tints visible to an expert gemmologist.

G Colour (Colourless)

The highest of the near-colourless group. G colour diamonds may show a faint tint when compared directly with higher grades, but once set they face up as beautifully white, making them an excellent balance of quality and value.

H Colour (Colourless)

The second grade in the near-colourless range. H colour diamonds generally appear white to the naked eye, especially when set in jewellery, and remain one of the most popular and best value choices.
