De Beers Diamond
Record: The Largest Missing Diamond In The World
In 1888, the De Beers Diamond was discovered in the Kimberly mines in South Africa. It was one of the largest diamonds ever found, and weighed 428 carats. After the diamond was cut, it became a magnificent 234.65 carat gemstone. The color of the diamond is pale yellow, and it holds a cushion cut of unknown clarity grade.
The De Beers diamond is currently the eighth-largest faceted diamond in the world. In 1928, the diamond became the centerpiece of the Patiala Necklace, which was created by the House of Cartier for Bhupinder Singh of Patiala. The necklace is one of most valuable pieces of jewelry every created. It contained 2,930 diamonds, including the 234.65 carat De Beers. The total weight of the Patiala Necklace was about 962.25 carats.
In 1948, the necklace disappeared. On May 6, 1982, it was reported that the De Beers diamond was put up for auction at Sotheby’s in Geneva, and fetched a $3.16 million bid, but did not meet the reserve. In 1998, part of the Patiala Necklace was located at a second-hand jewelry shop in London. However, all of the big gemstones were gone, including the De Beers diamond. As of 2013, the De Beers Diamond remains the largest diamond in the world that is not accounted for.
