Hue & sparkle


Diamonds are your all-time favourite, but do you sometimes wish your favourite diamond had a hue or two like rubies or emeralds? If you do, take your pick from coloured diamonds, which are all the rge now. Coloured diamonds come in shades of blue, red and green and these gems are both rare and expensive. For centuries, these diamonds have been the prized collection of royalty because of their beauty and extreme rarity;the dramatic increase in their popularity in the consumer market in the last decade is unprecedented. The GIA (Gemological Institute of America)grades these diamonds on the basis of the 4 Cs of diamond value: colour, clarity, carat weight and cut.

The rarest and most valuable coloured diamonds are red, blue, pink and green. The most important factor when evaluating a coloured diamond is the intensity of the colour. Naturally-occurringcoloured diamonds, such as the Hope and Dresden, are very rare and therefore command top prices; diamonds that have been colour-altered by laboratory treatment are less rare, and therefore less valuable. The style of the cut can also influence colour. Mixed cuts can intensify yellow colour in diamonds. Natural pink diamonds are very rare and extremely valuable. Rio Tinto controls the market for pink diamonds from the Argyle mines in Australia. Investors and collectors alike prize them. The 59.6-carat fancy Pink Stardiamond sold at auction for $83,000,000 in November 2013.
