A diamond coveted by kings,queens and princes for centuries,used to reinforce alliances between nations and pawned to pay off royal debts sold for 9 million Swiss francs ($9.57 million) at Sotheby’s in Geneva on Tuesday night.
The auction house called the Beau Sancy diamond one of the most important historic diamonds ever to come to auction,reflecting its role in the fluctuating fortunes of Europe’s royal families for more than 400 years.
The legendary Beau Sancy is a truly magical stone that has entranced generations of royal owners and continues to exert a powerful influence over all who see it,said David Bennett,Sotheby’s chairman of jewellery in Europe and the Middle East,in a statement.
Its supreme historical importance was reflected tonight in the strength of the bidding and the remarkable result realized.
No fewer than five bidders competed for the stone,driving the price to nearly five times above its pre-sale low estimate of 1.85 million Swiss francs in an eight minute battle before it was bought by an anonymous bidder,Sotheby’s said.
The stone,a 35-carat modified pear double rose cut diamond belonging to Georg Friedrich,Prince of Prussia and head of the former ruling dynasty of the German empire,had been expected to fetch $2 million to $4 million.
It’s a stone that appeals to me greatly as a survivor of all those tumultuous events,Bennett told Reuters in a telephone interview in February.
Stones from royal collections hardly ever appear at auction. In my career this is an absolute one-off.
Bennett,who sold a pink diamond for $46.2 million in 2010 in what was a record for any jewel at auction,said estimating the value of a stone like the Beau Sancy was difficult given its rarity.
The diamond originated from the mines in India near Golconda and was acquired by Nicolas de Harlay,Lord of Sancy,in Constantinople in the 1500s.
In 1604 it was bought for 75,000 livres by French king Henry IV as a gift for his wife,Marie de Medici.
According to Sotheby’s,the queen had long coveted the stone,especially after learning that de Harlay had sold a larger diamond called the Sancy,and now part of the Louvre Collection,to King James I of England.
Henry IV was assassinated in 1610,and after years of rivalry between Marie and her son King Louis XIII,she was eventually exiled in disgrace.
She escaped to the Netherlands,and to settle her debts her possessions were sold. This included the Beau Sancy,which was acquired by Prince Frederick Henry of Orange-Nassau for 80,000 florins,the largest expenditure in the state budget of 1641.
In the same year,the diamond was used as a sweetener to help seal the wedding of Frederick’s son William to Mary Stuart,daughter of King Charles I of England.
Following Mary’s death in 1660,the Beau Sancy was pawned to settle her debts. But in 1677 the stone reentered the Treasure of the House of Orange-Nassau following the wedding of William III to Mary II Stuart.
The couple ascended the throne of England in 1689,meaning the Beau Sancy entered the collection of the Queen of England. But since the couple had no children,the diamond returned to the Netherlands.
From there it moved to the Prussian monarchy in 1702,becoming the principal ornament of the new royal crown of Prussia.
The diamond remained in Berlin after the last king of Prussia fled to exile on the end of World War One in November,1918. At he end of World War Two,it was transferred to a bricked-up crypt for safe-keeping.
British troops found the stone and returned it to the estate of the House of Prussia,where it remained ever since.
