Pink diamond auctioned for almost 27 million

A large oval diamond known as the 'Pink Promise' was auctioned in Hong Kong for 26.

With the auction just a new record was not established. Eight years ago, a pink diamond in the so-called cushion-shape went under the hammer for 1.81 million per carat.

Christie's auction house speaks of a 'perfect masterpiece. '' The size was very important, the color top, an absolutely clean stone and beautifully polished ', said a spokesman the high price.

The highest price ever charged for a diamond per carat is 3.39 million euros per carat. That was for the Blue Moon of Josephine, a blue diamond of 12,03 carat, also in cushion shape.
