The blue diamond with a rectangular shape has been the rarest stone that has entered the international auction market this year. At the end of the auction the blue stone went to an anonymous buyer who was making his bids using the telephone after a hectic session of bidding between two of the unknown callers that lasted for a full and thrilling 15 minutes.
After, the stone had been auctioned off for the record price of 6.2 million pounds, David Bennett, the conductor of the auction told the reporters, "This is already a new world record price for a fancy vivid blue diamond and a new world record per carat for any gemstone at an auction. " He further added, "It is fantastic in this market and shows that these rare things are very much in demand."

The blue diamond was discovered on 2008 in South Africa and because then it had been highly marked for its vividness both in terms of color and clarity. The rectangular cushioned shaped diamond, which is smaller than a dime, is one of the rarest and only a handful of these blue gemstones exists at current or has ever been found.
