At 37.30 carats, the Raj Pink is the world’s largest known Fancy Intense Pink diamond, which will be auctioned by Sotheby’s in Geneva next month. Discovered in 2015, the rough was studied for more than a year before it was handed over to a master cutter to work his magic.
The shape that was chosen for the stone was a cushion-modified brilliant which, in addition to the radiant shape, is the best shape to use for fancy colour stones. Cushions, as well as radiant diamonds, allow for better colour saturation due to premium light absorption owing to the extra depth and shape of these stones. The facet arrangements are also great at masking imperfections, the Raj Pink has a clarity grade of VS1, impressive for a stone of its size.
Only one in 10,000 diamonds mined will be a rare fancy colour stone and these stones come in an array of colours and hues. Fancy colour diamonds range in intensity from light, fancy, intense, vivid and deep, which has the strongest colour; the Raj Pink has been graded Intense Pink by GIA, which is extremely rare for a diamond as sizeable as this. The Raj Pink was named by the diamond’s current owner, who wishes to remain anonymous, and is based on the Sanskrit word for ‘king’.
Fancy pink diamonds are among the rarest in the world, only preceded by red, green, purple and orange. The greater the colour intensity, the more valuable the stone. Diamonds such as the Raj Pink are truly exceptional as stones in this intensity and size are incredibly rare. Of all diamonds submitted to the GIA (Gemological Institute of America) every year, less than 0.02% are pink in colour.
Pink diamonds have only been unearthed in a few mines across the world. The majority of the world’s pink diamonds are found at the Argyle Mine in Western Australia, which is said to be closing in the next few years, making pink diamonds more sought after than ever and excellent investment stones.
The upcoming auction is called Magnificent Jewels and Noble Jewels on 15 November at The Mandarin Oriental, Geneva. Other impressive jewels to be auctioned at this exhibition include the Moussaieff fancy vivid blue diamond ring, 7.41ct and internally flawless (estimate: $14m-$18m) and the Property of a Countess, a fancy light pink diamond ring, 33.63ct, with a VVS1 clarity (estimate: $8m-$14m). The Raj Pink has been estimated to sell for $20m-$30m (approx. £15m).
The most anticipated item of the Geneva auction is The Art of De Grisogono, brought to auction by Christie’s, which is an enormous emerald-shape diamond of 163.41 carats; it will be the largest D-colour, flawless diamond to ever appear at auction. Set into an asymmetric necklace design by De Grisogono, the diamond is the largest ever found in Angola.
After months of analysis, the rough was cut in New York under the hands of more than 10 specialists over a period of approximately six months. The diamond was then sent to the jewellery design house who created an asymmetric necklace featuring 18 other emerald-shape diamonds. The necklace is currently on a worldwide tour until it goes under the hammer in Geneva on 14 November.
