Editor’s Note
A pair of extraordinary diamonds, including the 228-carat white diamond “The Rock” valued at up to $30 million, are heading to auction. This brief offers a glimpse into the rarefied world of high-stakes gem sales.

A giant diamond is set to be sold. Too large for a ring finger, the diamond “The Rock” is valued at 20 to 30 million dollars, weighs 228 carats, and is now scheduled for auction. For those for whom that is not enough: the auction house has another 200-carat stone on offer, albeit a yellow one.

Rahul Kadakia, Head of Christie’s Jewelry Department, made this statement. The imposing gemstone was mined and cut in South Africa over two decades ago. Not only its size but also its teardrop shape is extraordinary. The diamond will be auctioned on May 11 at the Four Seasons Hotel in Geneva. It will be sold alongside another stone, which is already being offered for sale for the third time.

Its yellow color comes from nitrogen atoms. The estimated selling price is between seven and ten million dollars. Parts of the proceeds will be donated to the International Red Cross. Kadakia views the auction with optimism.
