Rare blue diamond sells at auction

Overall, the jewelry market has seen signs of weakness lately but the tip of the market is still strong. The blue diamond shown above is a 13.39 carat stunner which sold for a world record price of $8.9 million at a sale at Christie’s in Geneva last Wednesday. Blue diamonds of this size are rather rare. The stone is a type IIb diamond.

Type IIb diamonds are prized by jewelry lovers and collectors and contain small amounts of boron which gives them their color. They also have the property of being semi-conductors that conduct electricity. The auction brought in nearly $48.3 million total.
