A 14.62-carat blue diamond owned by an architect of the modern diamond industry could break the record auction price set last year by fugitive Hong Kong tycoon Joseph Lau Luen-hung fetch a record price at this week’s Magnificent Jewels auctions in Geneva.
Mystery diamond buyer revealed: Hong Kong billionaire Joseph Lau spends US$48m on ‘Blue Moon Diamond’ for seven-year-old daughter
The dazzling rock previously belonged to the late Philip Oppenheimer, scion of the family that controlled the De Beers diamond mining company.
As chairman of a powerful cartel called the Central Selling Organisation, Oppenheimer – who died in 1995 – tightly controlled the international diamond trade and helped make it extremely lucrative.

His success will be on full display on Wednesday when Christie’s puts The Oppenheimer Blue under the hammer at the ultra-luxurious Four Seasons des Bergues hotel overlooking Lake Geneva.
How Joseph Lau’s US$48m diamond rates against five other big rocks
Christie’s has valued the Oppenheimer stone at between US$38 million and US$45 million, giving it an outside shot of breaking a record set by rival auction house Sotheby’s in November.
The 12.03-carat Sotheby’s diamond was bought for US$48.4 million by Lau, who a day earlier scooped up a 16.08-carat pink diamond for a comparatively modest US$28.5 million.

The property tycoon, who was convicted of bribery in Macau last year, named both stones after his daughter Josephine. Lau, who was handed a jail term of five years and three months by the Macau court, has not served time behind bars due to the lack of an extradition treaty between Hong Kong and Macau.
It’s a fabulous diamond, the most beautiful I have ever seen
Jean-Marc Lunel
Christie’s jewel expert Jean-Marc Lunel said The Oppenheimer Blue’s price could top what Lau paid for “The Blue Moon of Josephine”.
“It’s a fabulous diamond, the most beautiful I have ever seen and it could set a record price,” he said.
According to Christie’s, the Oppenheimer diamond is the largest ever sold at auction in the exclusive fancy vivid blue category, which groups rare gems of exceptional colour and clarity.

There is always a chance that the jewel will not even meet its estimated floor price, though. That happened last month when a 9.54-carat blue diamond ring once owned by American child star Shirley Temple failed to sell at auction in New York after bidding closed at US$22 million, below the reserve price.
Christie’s has valued its total of 280 lots up for auction on Wednesday at US$113 million. The collection includes 46 pieces from German-born princess Gabriela zu Leiningen, who was married to the Aga Khan.
Sotheby’s kicks off Geneva’s Magnificent Jewels week on Tuesday with a 495-lot offer valued at US$140 million, the highlight of which is a 15.38-carat pink diamond.

Categorised as a fancy vivid blue diamond, the Blue Moon, discovered in South Africa in January last year, is the largest cushion-shaped stone in that category to ever appear at auction.
