Rare blue diamond sells for £6.2million

A tiny but rare blue diamond has been sold at auction for a record breaking 10.5 million Swiss francs, that is £6.2million.

It is smaller than a 1p coin and weighs just 7.03 carats but because of the rarity of blue diamonds it had a massive price tag.
 
The diamond was sold at a Sotheby's auction in Geneva to a unnamed phone bidder who plans to have it mounted on a platinum ring.

While the bidder wanted to retain his anonymity his wife probably won't be so modest and will show the ring off to friends at every opportunity telling them just how much it cost.
