3 Most Expensive Diamonds in the World

Take a look at some of the world’s most expensive cut and polished diamonds

1

Pink Star Diamond

Auctioned by Sotheby’s Hong Kong in 2017, the Pink Star was acquired by famed jeweller Chow Tai Fook and renamed CTF Pink Star in a nod to the brand, which is currently led by chairman Henry Cheng. It went under the hammer after just five minutes of bidding for a staggering US$71 million, setting a new world record for any gemstone at auction.

Oppenheimer Blue Diamond

Previously owned by British diamond dealer and racehorse owner Sir Philip Oppenheimer, the Oppenheimer Blue set a world auction record in 2016 when it sold for more than US$57.5 million at Christie’s Geneva Magnificent Jewels sale. The 14.62-carat stone was the largest fancy vivid blue diamond ever offered at auction and was set into a platinum ring between two trapeze-shaped diamonds.

3 Blue Moon of Josephine Diamond

When Blue Moon sold for US$48.4 million at a 2015 Sotheby’s auction in Geneva, auctioneer David Bennett said it had obtained the “highest price per carat” for any kind of gemstone. CNN later confirmed that Hong Kong billionaire Joseph Lau bought the diamond and renamed it after his 7-year-old daughter, Josephine.
