This $60 million diamond is called the ‘Pink Star’ for a reason

The most valuable diamond to ever be offered at auction is going under Sotheby’s hammer on November 13, with experts predicting it will fetch a record-breaking $60 million.

Described as one of “the earth’s greatest natural treasures”, the oval-cut 59.6 carat “Pink Star” is the largest flawless pink diamond that the Gemological Institute of America (GIA) has ever graded.

First unveiled to the public in 2003, the rock was called the “Steinmetz Pink,” but it was renamed after it was first sold for an undisclosed sum in 2007.

The internally flawless vivid pink gem is more than twice the size of the 24.78-carat “Graff Pink” diamond that set the world auction record for a diamond and any gemstone or jewel when it was sold at Sotheby’s Geneva in 2010 for $46.2m, the auction house said.

Its sale will follow the Hong Kong auction coming up in October, which contains a white and a blue diamond valued at more than $28 million and $19 million each.
