Gem diamonds in GIA’s D-to-Z range usually decrease in value as the colour becomes more obvious. Just the opposite happens with fancy colour diamonds: Their value generally increases with the strength and purity of the colour. Large, vivid fancy color diamonds are extremely rare and very valuable. However, many fancy diamond colors are muted rather than pure and strong.

Only one in ten thousand diamonds has a fancy colour.
Champagne & Cognac Diamonds are mostly mined in Australia with a large amount coming from the Argyle Mine.
Pink Diamonds are rarely found outside Australia.
With only a handful of pink diamonds found every year and of that handful, five or six will be more than one carat. About 75 per cent of Argyle pink diamonds are less than a quarter of a carat. These natural treasures are an artwork beyond measure.
Pretty & Pink...
Never before, and never since, has there been a diamond mine that consistently produces rare pink diamonds like the Argyle Diamond Mine. All of the Argyles diamond are graded by the GIA.
Coloured diamonds are often cut in fancy shapes, like the radiant cut.
Cutters do this because a diamond’s cut can have a noticeable impact on its apparent colour when viewed from above. Cutters will even recut diamonds to maximize the intensity of the diamond’s face-up colour.
