“The Rock”, the biggest white diamond ever auctioned, was auctioned again on Wednesday for 21.68 million Swiss francs (20.67 million euros), slightly beating the lower range of the estimate made by auctioneer Chistie’s, which sold at auction in Geneva.
The gemstone weighs 228.31 carats and is so large that it takes up almost the entire palm of a hand.
Christie’s had valued it at between $20 million and $30 million and ended up selling it just above the minimum margin, but the company noted that the price obtained represents a new world record for a diamond of this type, which was the highest to be auctioned in history through this type of transaction.
The buyer bid at the last moment by phone to add more than 95,000 euros to what appeared to be the last bid that had been launched by a person from the room of a prestigious hotel in Geneva where the jewelry auction took place.
This diamond was mined from a South African mine earlier this century and is on sale for the second time since its discovery.
In 2006 it was sold at auction in the United States to a private collector, who placed it in a Cartier necklace.
In today’s auction, the diamond called “Diamond of the Red Cross”, of 205 carats, was also sold. Swiss (13.5 million euros).
This diamond has a special relationship with Christie’s, as this is the third time it has been sold.
The first time was 104 years ago and the most recent time in 1973, when it reached the price of 1.8 million dollars, which today has practically been multiplied by eight.
Part of the proceeds from this sale will go to the International Committee of the Red Cross, the largest humanitarian organization working in conflict and disaster scenarios, although the amount was not specified.
