Whilst most diamonds appear white, many of them display hints of colour barely discernible to the naked eye. The closer a diamond approaches colourless, the rarer and more valuable the stone.
Diamonds with a strong pure colour are extremely rare and are called 'fancies'. Amongst them can be found pink, blue, yellow, green and orange.
