Diamond colour
Diamond Buyer's Guide
Diamonds mostly appear colourless. However, many actually contain subtle shades of yellow or brown. The closer a diamond is to having no colour, the more valuable it becomes, because the light is free to play through it giving you a truly dazzling diamond. Diamonds can also be found in what are known as 'fancy' colours, including yellow, brown, pink and blue. These are extremely rare and valuable.
Black Diamonds
Our Black diamonds are natural diamonds which have been subjected to specialist treatments to enhance the depth of colour and contrast. The effect is permanent and the product can be treated the same as your regular diamond jewellery. We would, however, advise that excessive heat is avoided.
Diamond colour scale
At Ernest Jones, we use the GIA (Gemological Institute of America) scale of colour. On this scale, diamond colour is graded from D, which has the least colour, through the alphabet to Z, which has a light yellow colour. Truly colourless diamonds (D) are treasured for their rarity.
Subtle diamonds
The colour differences between diamonds are very subtle. It can be hard, for instance, to tell the difference between and E and F diamond and it can take years of experience and training to fully appreciate the subtleties. If you want to see the difference for yourself, however, ask a diamond specialist at your local Ernest Jones store to compare diamond engagement rings side by side.
Certificated diamonds
At Ernest Jones we only state the colour of certificated diamonds. We do not otherwise state the clarity of our diamonds.
