Rare blue diamond smashes auction record
HONG KONG (AFP) - A rare, flawless blue diamond has been snapped up at a Sotheby's sale here for 7.98 million US dollars, making it the most expensive gemstone in the world per carat ever bought at auction.

I'll make them an offer they can't refuse. Then, I'll spend hundreds of thousands of dollars insuring it, I'll lock it away somewhere where thieves can't get to it, I'll spend thousands of dollars on security to protect the place I locked it up at, I'll let my wife wear it once or twice a year, just so we won't tempt anyone to kill us for it; and I'll do it all so I can say I own the world's most expensive polished rock.

Either that; or, I'll take the money and feed Ecuador for a year.
