The flawless pink diamond is one of the greatest natural diamonds in the world and Fancy vivid pink color is the highest possible color grade for a pink diamond that is highly demanded. It was cut from a 132.5-carat rough diamond mined by De Beers in Africa in 1999. This diamond has broken the world record for any gem sold at auction and this is why it is ranked by Guinness as the most expensive diamond sold at auction. It was sold on November 12, 2013 at Christie’s in Geneva, Switzerland. Isaac Wolf won the auction and got the oval-shaped 59.60-carat “Pink Star” diamond for just $83.01 million. Cutting and polishing this magnificent diamond took two years to come as the most expensive jewelry piece in the world. - See more at: http://www.topteny.com/top-10-most-expensive-diamond-rings-necklaces-in-the-world-2015/#sthash.IykWQOn3.dpuf
