The colour of the diamond is one of the fundamental attributes (one of the 4 C's) to knowing how to judge a diamond, which is important when matching with diamond jewellery or engagement rings. Colour stands for how white or colourless a diamond is; the better the colour grading, the more white or colourless the diamond will be and the more sparkle or fire it will have. Generally, white or colourless diamonds are rarer and more highly valued. However, as a note of interest, certain evenly coloured diamonds are also highly valued due to their rarity (such as the Steinmetz Pink diamond - 59.60 carats).
Diamonds are graded according to GIA's colour scale which begins with D for perfectly white or colourless and continues all the way to Z which is brownish in colour. For diamonds on this website, we focus on the best quality diamonds, which start with D and go through to diamonds which have light yellow colouring (J).
