The diamond that is forever blue goes for £14.1 million, setting a new world auction record

The largest flawless vivid blue diamond in the world has sold for £14.1 million ($23.8 million)

It announced today that a 1912 Cartier diamond brooch brought $17.5 million, which is 660 percent more than when it was first sold at Christie's in Geneva in 1991, while a pear-shaped and D-color flawless 75.97-carat diamond sold for almost $14.5 million.

'It is absolutely perfect, absolutely pure externally and internally. It is almost a dream,' said Jean-Marc Lunel, senior international specialist of Christie's jewellery department of The Blue. 

'We are quite confident that it should sell towards the high end of the estimate or above.'

Based on results from sales in Hong Kong and New York this year, the jewelry market is quite strong, Lunel said.

'The market for colored diamonds is really, really high, because they are so rare,' he said.

'For what is really exceptional, not seen on the market, there are really clients looking for such investments,' Lunel added.

'Chinese clients are not only buying in Asia but in New York and Geneva as well.'
