Coloured Diamonds

Understanding more

Coloured Diamonds are a quirk of nature, formed billions of years ago deep below the earth’s surface. These special diamonds acquired their colours, shades and tones from additional trace elements and distortions to a typical diamond structure.

On average, for every one million carats of diamonds mined there is only one gem quality 1 carat diamond found and it takes on average five million diamonds to find a single 2 carat diamond with around two hundred tons of Kimberlite mined to find just one single diamond.

90% of diamonds that are found are only industrial quality and of the 10% that remain less than 1 in 10,000 are fancy coloured. Of the fancy colours that remain we source the top 1% of these for our clients

Many colourless or white diamonds possess very subtle hints of yellow or brown and are still classified within the D to Z colour scale reserved for white diamonds.

When a colour is strong enough and of a different hue it is known as a fancy coloured diamond and sits within this special group known as natural fancy coloured diamonds.There are twelve different main fancy colours and many shades in between.

In 2003 a 3.58ct Fancy Intense Pink diamond was sold for $115,000 per carat and in 2011 a 4.59ct Fancy Intense Pink diamond was sold for $625,000 per carat. Sothebys and Christies Auction Houses”

All Natural Fancy Coloured Diamonds are graded by their saturation, hue and tone. Saturation is the strength or intensity of the colour, hue indicates the dominant colour of the stone and the tone describes how much lightness or darkness the stone retains.

Most Natural Fancy Coloured Diamonds possess combinations of different hues and shades. Secondary hues are known as ‘overtones’ or ‘modifiers’, for example, if a Yellow diamond has a slight orange tint or shade it will be called Orangey Yellow (the last colour in the description being the dominant colour). It is then given one of nine colour saturation descriptions:

  • Faint
  • Very Light
  • Light
  • Fancy Light
  • Fancy
  • Fancy Dark
  • Fancy Intense
  • Fancy Deep
  • Fancy Vivid
