Colours

Colourless diamonds are the most desirable since they allow the most refraction of light (fire and brilliance) but lower colour’s can give you excellent choices in terms of size and budget which have lots of fire and brilliance especially when clean.

While the vast majority of diamonds fall in the D-to-Z colour range, nature occasionally produces diamonds with a naturally occurring blue, brown, pink, deep yellow or even green hue. The geological conditions required to yield these colours are rare, making diamonds with distinct and naturally occurring shades scarce and highly prized.

Unlike colourless and near-colourless diamonds, fancy-colour diamonds are evaluated less for brilliance or fire and more for colour intensity. Shades that are deep and distinct are rated higher than weak or pale shades.

GIA describes colour in terms of hue, tone and saturation. Hue refers to the diamond's characteristic colour, tone refers to the colour's relative lightness or darkness and saturation refers the colour's depth or strength. Using highly controlled viewing conditions and colour comparators, a fancy colour grader selects one of 27 hues, then describes tone and saturation with terms such as "Fancy Light," "Fancy Intense," and "Fancy Vivid."
