Christie’s auction house in Hong Kong has probably seen every type of stone over the years. However, it could not help but be taken aback by the rarity of a unique 5-carat pink diamond that turned up at the auction house earlier this week, reports Tonic.com



The fact that the large stone market has been deeply affected by the financial crisis did not stop one particular Asian buyer from bidding a record-breaking $10.8 million for the unusual gem.



The diamond with its "vivid pink" hue is almost perfect and is “probably one of the rarest I've ever seen." Said Christie's Europe chairman, Francois Curiel.



The unusually colored diamond fetched no less than $2.2

million-per-carat - the highest price ever paid for a diamond at an auction.



"We were used to ... a million dollars a carat for colored diamonds but never 2 million," said Curiel. "This is an absolute record that is not going to be broken for a while I believe."
