Most Expensive Ring Ever Sold at Auction
The most expensive ring ever sold at auction is the Graff Pink, a 24.78 carat fancy intense pink diamond ring that set a world record for any gemstone sold at auction. It sold at Sotheby's Geneva in November 2010 for approximately 46 million Swiss francs, or about 46.16 million USD at the time, to anonymous buyer Laurence Graff, founder of Graff Diamonds. The ring was designed by Laurence Graff and features a rectangular brilliant cut pink diamond graded by the Gemological Institute of America as fancy intense pink, VS2 clarity, with a colour grade that places it among the rarest coloured diamonds ever discovered. The sale was confirmed by Sotheby's and widely reported by major financial and luxury outlets, including Forbes, which detailed the record price and the buyer's identity in its coverage of the Geneva Magnificent Jewels sale. The Graff Pink remains the benchmark for coloured diamond ring valuations and is regularly cited in industry reports on high jewellery and rare gemstone sales.
Before the Graff Pink, the previous record for the most expensive ring ever sold was held by the Wittelsbach Graff Diamond, a 31.06 carat deep blue diamond ring that Laurence Graff acquired at auction in 2008 for about 24.3 million USD and later recut and resold. The Wittelsbach Graff Diamond ring was originally part of the Spanish Habsburg and Bavarian Wittelsbach royal collections and sold at Christie's London in December 2008. After Laurence Graff purchased it, he had the diamond recut to improve its brilliance, which altered its historical finish but increased its market value. The ring was later set into a new design and offered for sale, with its valuation reflecting both its royal provenance and the rarity of large fancy deep blue diamonds. These transactions illustrate how historic provenance, colour rarity, and expert cutting drive the highest prices in the global jewellery auction market.
Most Expensive Private Sale Ring
The most expensive ring ever sold in a private transaction is the Blue Moon of Josephine, a 12.03 carat fancy vivid blue diamond ring that sold in 2015 at Sotheby's Geneva for 48.4 million Swiss francs, or approximately 48.5 million USD, to Hong Kong billionaire Joseph Lau, who named it after his daughter. The sale price included Sotheby's buyer's premium and made it the most expensive jewel ever sold at auction at the time, with the ring achieving a per carat price of over 4 million USD. The Blue Moon of Josephine is a cushion cut diamond with a fancy vivid blue colour grade and VS2 clarity, graded by the Gemological Institute of America, and it was set in a platinum ring by Lucida Diamonds, a brand associated with Sotheby's high jewellery auctions. The transaction was reported by Sotheby's and covered by luxury and finance media, with details about the buyer and the record per carat price widely cited in industry analyses of blue diamond valuations.
Private sales of ultra rare rings can exceed auction records when the seller and buyer negotiate directly, bypassing auction house premiums and public disclosure. In such transactions, the price is often driven by the scarcity of the gemstone, the prestige of the brand or designer, and the confidentiality desired by the parties involved. High net worth collectors and family offices frequently acquire record breaking rings through private channels, with the details emerging later through regulatory filings, news reports, or auction house retrospectives. These sales highlight the role of specialist brokers, trusted advisors, and rare gemstone dealers in facilitating transactions that set new benchmarks for the most expensive rings ever sold outside of public auctions.
