The Largest Most Valuable Pink Star Diamond

The Largest Most Valuable Pink Star Diamond

Pink Star (Diamond), the most valuable cut diamond ever offered at auction is displayed by a model at Sotheby’s auction rooms in London, Monday, March 20, 2017. It is the largest internally flawless fancy vivid pink diamond ever graded by the GIA. The diamond estimated in excess of 60 million US Dollars will go for auction in Hong Kong on April 4.

The Pink Star was cut from a 132.5-carat rough diamond mined by De Beers in Africa in 1999. It took two years of meticulous cutting and polishing to hone it into its current oval shape. The current record price for a pink diamond sold at auction is the $46.2 million achieved by the 24.78-carat Graff Pink, which sold at Sotheby’s Geneva in 2010. The Pink Star is more than twice as big as the Graff Pink, and its colour rating, ‘Fancy Vivid’, is the highest possible grade on the scale used to assess coloured diamonds, and therefore considered the most valuable.

The pink diamond is also rated as Internally Flawless, meaning it has no internal inclusions, and is a Type IIa stone, the coveted classification given to less than two per cent of all gem-quality diamonds, which signifies chemical purity.
