Petra Diamonds Ltd. found a buyer for the 20.08-carat blue diamond it unearthed in South Africa earlier this fall.
The diamond miner recovered the stone from the Cullinan Mine in September, and sold it via a tender held at its diamond marketing offices in Johannesburg earlier this month for $14.9 million, or about $741,000 per carat.
Cathy Malins, a Petra spokeswoman, said in the 10 years the company has been operating the mine this is the second highest price per carat achieved for a blue diamond, a “testament to its very high quality.”
The highest was a 29.6-carat blue rough that sold for $25.6 million, or nearly $863,000 per carat. That stone was cut into a 12-carat diamond that sold for $48.5 million in 2015 and was dubbed the “Blue Moon of Josephine.”
Petra said a “leading diamond company” bought the 20.08-carat stone but wishes to remain anonymous.
Petra Chief Executive Richard Duffy said in a press release the result is what the company expected and “confirms the resilience in the value of very high-quality blue diamonds.”
“We look forward to following this exceptional stone’s journey to its polished form.”
Also on Friday the 5th of November, the London-based diamond miner announced it is restructuring in order to better support its operations and speed up implementation of Project 2022, a three-year plan to cut debt.
The mines now report directly to Chief Executive Richard Duffy, and the chief operating officer role has been eliminated.
