Most Expensive Diamonds Sold at Auction

One of the most exciting platforms in the world of diamonds is the auction platform, where the finest jewels are auctioned to the highest bidder. Many stones will appear in the roster, but the most unique, the largest, and the highest quality diamonds selected always become the highlights to these prestigious events. Viewing these items is just a small portion of the appeal. The peak of the drama is when the hammer comes down and a final sale price is announced. When that sum breaks a record, the excitement cannot be contained.

 

Can you imagine the excitement of those in the industry now that we are so quickly approaching the auction that will likely include the most expensive diamond yet to be sold at auction? With the enormous 59.60-carat Fancy Vivid Pink diamond about to be auctioned off for a steep estimate of $60, million, which will surely be exceeded, it is only fit to take a look back at some of the most expensive diamonds ever sold at auction.

 

Most Expensive Diamond Ever Sold At Auction: The Graff Pink $46 Million


At 23.88 carats, the Graff Pink became famous, not for its large size, but for the high sum paid for it at auction. The rare pink diamond was bought for over $46 million by Laurence Graff, hence the name. The renowned Harry Winston sold the stone 60 years ago, which now resides in a private collection. The Graff Diamond is currently the most expensive diamond ever sold at auction.

The Wittelsbach-Graff Diamond – $24.3 Million


Another extremely expensive diamond, also with the Graff name, is the Wittelsbach-Graff Diamond, this time a Fancy Deep Grayish Blue diamond weighing 31.06 carats. The jewel dates as far back as 1664 and carries an intriguing story. Philip IV of Spain gifted his daughter with the fabulous stone in honor of her engagement. The diamond has been passed through royalty, misplaced, recovered, bought and sold, until it finally found its home with Laurence Graff in 2008, when it was purchased for $24.3 million. In order to enhance the color, Mr. Graff had the diamond cut down to its current 31.06-carat size, which enabled it to receive a Fancy Deep Blue Internally Flawless grading.
