'Yellow' diamonds -- the colour, can range from diamond clarity M-Z in colourless diamonds, and from "Faint, Very Light, Light, Fancy Light, Fancy, Fancy Dark, Fancy Intense, Fancy Deep, to Fancy Vivid" in fancy diamond colour. Every diamond is valued by its cut, colour, clarity and carat weight: of these, there is no 'average'. Generally, however, you will pay less for a colourless diamond rated M-Z in colour than you will pay for a similar diamond rated as 'faint yellow'.

'Fancy' is a term used to modify the colour of a diamond, which is not white. Fancy applies to all coloured diamonds, the most common of which is fancy yellow. Be aware, however, that naturally fancy coloured stones are more rare than other diamonds. There are some applications of 'treatments' which can highlight a stone's colour, and sometimes these treated stones are sold as fancy coloured diamonds. Any treated diamond which enhances its colour should be labeled as 'treated', and will cost much less than a naturally fancy coloured diamond. A certified gemologist will help you determine how a fancy diamond obtained its colour. You can read more about fancy colour diamonds, below.
