Colour

Colour is the second of the 4 C’s to be considered in terms of rarity and value.

Acting as a prism a diamond can divide light into a spectrum of colours and reflect this light as colourful flashes called fire.The less colour in a diamond, the more colourful the fire, and the better the colour grade.

Just as when looking through coloured glass, colour in a diamond will act as a filter, and will diminish the spectrum of colour emitted.
The less colour or tint the greater the value, with totally colourless diamonds commanding the highest premiums.
