A rare pink diamond of 170 carats discovered in Angola recently is being feted as the largest such gemstone found in 300 years.
Called the “Lulo Rose”, it was found at the Lulo alluvial diamond mine in Angola’s Lula Norte region, the mine’s owner, the Lucapa Diamond Company, announced on Wednesday on its website.
“Only one in 10,000 diamonds is coloured pink. So you’re certainly looking at a very rare article when you find a very large pink diamond,” Lucapa CEO Stephen Wetherall told the Associated Press news agency.
The pink gemstone is expected to fetch a high value when auctioned, but Wetherall said he did not know what kind of premium will be paid because of its colour.
Lulo is an alluvial mine which means the stones are recovered from a riverbed.
Lucapa is searching for the underground deposits, known as kimberlite pipes, which would be the main source of the diamonds, said Wetherall, speaking from the company’s headquarters in Australia.
“We’re looking for the kimberlite pipes that brought these diamonds to the surface,” Wetherall said. “When you find these high-value large diamonds … it certainly elevates the excitement from our perspective in our hunt for the primary source.”
He said about 400 people are employed at the mine, which has already produced the two largest diamonds ever found in Angola, including a 404-carat clear diamond.
The pink gemstone is the fifth largest diamond found at the mine, where 27 diamonds of 100 carats or more have been found, according to Lucapa.
The pink diamond will be sold by international tender by the Angolan state diamond marketing company, Sodiam.
“This record and spectacular pink diamond recovered from Lulo continues to showcase Angola as an important player on the world stage for diamond mining and demonstrates the potential and rewards for commitment and investment in our growing diamond mining industry,” Diamantino Azevedo, Angola’s minister of mineral resources, petroleum and gas, said, according to the Lucapa website.
The pink diamond is impressive, but many clear diamonds are larger than 1,000 carats.
The Cullinan diamond found in South Africa in 1905 tips the scales at 3,106 carats and it is in the British Sovereign’s Scepter.
