The ‘Red Cross Diamond’ is among the largest diamonds in the world and is shaped like a Maltese cross.
The largest white diamond ever sold at auction, dubbed “The Rock,” is up for auction in Geneva on Wednesday and could fetch $30 million or more.
The 228.31-carat stone is up for grabs along with a historic deep yellow diamond associated with the Red Cross for more than a century, which will receive part of the proceeds from its sale.
It is “the largest white diamond ever offered at auction,” he told AFP at a preview on Friday.
It could even break records when it goes under the hammer.
The equivalent in euros is between 19 and 28 million.
Larger than a golf ball, The Rock was mined in South Africa in the early 2000s. It has been shown in Dubai, Taipei and New York before going on sale in Geneva.
Bidders will also compete for The Red Cross Diamond, a 205.07-carat cushion-shaped canary-yellow gem estimated to cost between 7 and 10 million Swiss francs ($7.09-10.13 million). ).
A large portion of the proceeds will be donated to the International Committee of the Red Cross, which is based in Geneva.
As well as being ranked among the largest diamonds in the world, a striking feature is its pavilion, which is naturally in the shape of a Maltese cross.
The Red Cross Diamond earned £10,000, approximately £600,000 ($740,000) in today’s money. It was purchased by London jewelers SJ Phillips.
“For nearly half a century, our family has been privileged to safeguard the Red Cross Diamond,” the gem’s anonymous private owner said in a statement.
Several other diamonds will be auctioned on Wednesday, as well as a tiara that belonged to Princess Irma of Furstenberg (1867-1948), a member of one of the most prominent aristocratic families of the Habsburg Empire.
“The diamond market right now is very, very strong,” Fawcett said.
The Russian invasion of Ukraine has had a huge impact.
The supply constraint has created significant price increases and with the sanctions imposed on Moscow after the February 24 invasion, “prices will continue to rise,” he said.
