A 170-carat pink diamond discovered in Angola may be the largest such gemstone found in 300 years, according to Australian miner Lucapa Diamond Company.
Named the “Lulo Rose,” the diamond was found at the Lulo alluvial diamond mine in the Lunda Norte region of Angola in Africa, the company said in a statement on Wednesday, with its partners, state-run diamond miner Endiama and Rosas & Petalas, a private Angolan company.
Angola’s mines are among the world’s top ten producers of diamonds, according to the Gemological Institute of America, which researches diamond production. In alluvial diamond mining, stones are recovered from gravel and sand found on riverbeds.

Only one in 10,000 diamonds found are colored, according to Stephen Wetherall, managing director of the Lucapa Diamond Company.
“And only one in every 100 diamonds is greater than 10.8 carats in size, so recovering a 170-carat pink diamond means we are dealing with an extremely rare article,” Wetherall said.
“We have recovered pink diamonds before, but finding one this size is extremely rare,” he said.
The pink gemstone is expected be auctioned by the Angolan state diamond marketing company, Sodiam. Wetherall declined to give an estimate of its worth because the diamond is still being examined and valued.
The Angolan government also hailed the “historic” recovery of the gem.
