Diamond Colour

Diamonds come in a range of natural colours, including blue, green, yellow-orange, pink and red. These types of diamonds are referred to as ‘coloured fancies’ and are extremely rare and valuable. They are graded according to the intensity of their colour. White or colourless diamonds come in a range of shades, from truly colourless to off-white, and are graded on a colour scale from D (colourless) to Z. The shade differences between diamonds are very subtle, so grading is done under controlled lighting using a master diamond sample set for comparison and accuracy.
