The Pink Star, a 59.60 carat pink diamond, was cut out of a 132.5-carat rought diamond mined by De Beers in Africa in 1999. Polish over a period of two years, the diamond is the largest Internally Flawless Fancy Vivid Pink diamond that the Gemological Institute of America (GIA) has ever graded and 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 at $46.2 million.

The  oval mixed cut pink diamond rock will be offered at Sotheby’s Hong Kong on April 4, as part of its magnificent jewels and jadeite sale and is estimated to fetch in excess of $60 million. (UPDATED April 5: The diamond sold for $71.2 million to Hong Kong jeweler Chow Tai Fook, a new world record for any diamond or jewel. It was renamed The CTF Pink. )
