The Pink Star - The Most Valuable Cut Diamond Ever Offered at Auction Unveiled Today in London

20 March 2017

Sotheby’s announces today that The Pink Star, one of the world’s great natural treasures, will lead its sales of magnificent jewels and jadeite in Hong Kong on 4 April 2017. Estimated in excess of US$60 million / HK$468 million*, this 59.60-carat oval mixed-cut  pink diamond is the largest Internally Flawless Fancy Vivid Pink diamond that the Gemological Institute of America (GIA) has ever graded.

Announcing the forthcoming sale of The Pink Star, David Bennett, Worldwide Chairman of Sotheby’s Jewellery Division, said: “At a time of unprecedented demand for the finest in coloured diamonds, I am delighted to be bringing this magnificent stone back  to the market. The extraordinary size of this 59.60-carat diamond, paired with its richness of colour, surpasses any known pink diamond recorded in history.”

QUEK Chin Yeow, Deputy Chairman, Asia, and Chairman International Jewellery, Asia, said, “Over the years Sotheby’s Hong Kong has played host to many outstanding stones and sales; including the 118.28-carat oval D-colour flawless diamond sold in Oct 2013, the still-current world auction record for any white diamond, as well as the fancy vivid blue 10.10-carat De Beers Millennium Jewel 4 which set a record for any jewel sold at auction in Asia in April 2016. The market for the world’s finest diamonds and gem stones remains buoyant and Sotheby’s Hong Kong is honoured to present at auction the Pink Star this spring following these wo rld records.”

The Most Valuable Polished Diamond Ever Offered at Auction

The Pink Star has received the highest colour and clarity grades from the GIA for pink diamonds and has been found to be part of the rare subgroup comprising less than 2% of all gem diamonds - known as Type IIa: stones in this group are chemically the purest of all diamond crystals and often have extraordinary optical transparency. Mined by De Beers in Africa in 1999, the 132.5-carat rough diamond was meticulously cut and polished over a period of two years and transformed into this stunning gemstone. According to the records of the GIA Laboratory, The Pink Star is the largest Flawless or Internally Flawless, Fancy Vivid Pink, Natural Colour, diamond they have graded in a letter issued in April 2016.

At 59.60 carats, The Pink Star is more than twice the size of the ‘Graff Pink’ – the 24.78-carat Fancy Intense Pink diamond which currently holds the world auction record for any pink diamond. Sold at Sotheby’s Geneva in 2010, for US$46.2 million, the Graff  Pink also marked an auction record for any diamond or gemstone at the time.

The sale of The Pink Star continues Sotheby’s tradition of bringing some of the rarest and most extraordinary collectibles to market. Sotheby’s has sold a number of the most valuable diamonds in the world, and holds the current price-per-carat auction record for any diamond or any gemstone with The Blue Moon of Josephine, a 12.03-carat cushion-shaped Internally Flawless Fancy Vivid Blue diamond that sold for US$48.5 million at Sotheby’s Geneva in 2015.
