Petra’s Prices Boosted $8.2m Blue

Petra’s Prices Boosted $8.2m Blue

Petra Diamonds sold fewer carats but achieved higher prices earlier this month at its fifth tender of FY 2024, boosted by the sale of an $8.2m blue diamond.

The UK-based miner achieved an average $136 per carat on sales of 362,000 carats for $49m.

Like-for-like figures for its fourth tender, in February, were $112 per carat on sales of 429,000 carats for $48m.

Sales for the year to date are, however, lagging behind FY 2023, at $285m, down 10 per cent down on $316m.

The 14.76ct exceptional color and clarity blue diamond recovered from Cullinan, South Africa, sold for $8.2m, although it was not classified as an “exceptional stone” (over $15m).

Total revenue for Q3 FY 2024 was $66m, down 27 per cent on the previous quarter, due to the lower production and the timing of receipts from the fifth tender.

“Production for the quarter is consistent with the preceding quarter and in-line with expectations.,” said CEO Richard Duffy.

Production guidance for FY 2024 is 2.75m to 2.85m carats.

Earlier this month Petra announced the sale of its loss-making Koffiefontein mine, in South Africa, to Dubai-based Stargems for a nominal sum.

Sotheby’s Rakes In $57.5M for De Beers Blue

A record blue diamond co-owned by De Beers far outstripped its presale estimate in a stand-alone sale at Sotheby’s in Hong Kong, garnering HKD 450.9 million ($57.5 million), the auction house said Wednesday.




The 15.10-carat De Beers Cullinan Blue diamond

The step-cut, 15.10-carat, fancy-vivid-blue, internally flawless stone, called the De Beers Cullinan Blue, is the largest of its color to appear at auction. The stone, which sold to an unnamed buyer, had been expected to fetch up to $48 million.


Petra Diamonds discovered the 39.35-carat rough in April 2021 at its Cullinan mine in South Africa. In July, De Beers and Diacore bought the stone for $40.2 million, and Diacore manufactured the piece into the final polished.



To date, only five blue diamonds weighing more than 10 carats have come to auction, none of which has exceeded 15 carats, Sotheby’s explained. Similar blue diamonds have also fetched high prices, including the Blue Moon of Josephine, a cushion-shaped, 12.03-carat, fancy-vivid-blue, internally flawless diamond that sold for $48.5 million at Sotheby’s Geneva in 2015. Meanwhile, the Oppenheimer Blue, a step-cut, 14.62-carat, fancy-vivid-blue, VVS1-clarity stone, garnered $57.5 million at a Christie’s Geneva sale in 2016.

De Beers Cullinan Blue Diamond Could Bring $48M at Auction

De Beers Cullinan Blue Diamond

Sotheby’s will auction a stone described as “the largest vivid blue diamond ever to appear at auction” on April 27 in Hong Kong.

Sotheby’s estimates that it could bring $48 million.

Cullinan Blue Diamond

The 15.1 carat step-cut blue was cut from a rough stone discovered in April 2021. It is “the largest internally flawless step cut vivid blue diamond that the Gemological Institute of America (GIA) has ever graded,” according to a press statement.

“This diamond ranks as one of the best De Beers has ever seen,” said Bruce Cleaver, CEO of De Beers Group. “It is extremely rare and unique, and as the Home of Diamonds, De Beers is pleased to join together with Sotheby’s to bring this diamond to the world.”

Only five blue diamonds over 10 carats have ever come to auction, Sotheby’s notes. Until now, none has exceeded 15 carats.

“Blue diamonds of any kind are rare on the market, but this is the rarest of the rare; nothing of remotely similar calibre has appeared at auction in recent years,” says Patti Wong, chairwoman of Sotheby’s Asia. “Hundreds of millions of years in the making, this extraordinary blue diamond is surely one of nature’s finest creations.

The diamond comes from the Cullinan mine in South Africa.

Petra Diamonds finds 342-carat rough at Cullinan mine


            342.92-carat Type IIa white diamond.

South Africa’s Petra Diamonds has recovered a 342.92-carat Type IIa white rough at its iconic Cullinan mine.

The company said the diamond is “exceptional” quality, in terms of both its colour and clarity, and that it will likely be sold at the September tender.

Petra fetched in March $12.2 million for a 299.3-carat Type IIA white diamond. That meant it obtained $40,701 per carat, which exceeds the $34,386/ct received for the 424.89-carat “Legacy of the Cullinan Diamond Mine” in May 2019.

Type II diamonds are found less frequently and are more valuable than Type I diamonds, as they have no measurable nitrogen impurities. This gives them exceptional transparency and brilliance.

Cullinan is known as the birthplace of the famed 3,106-carat Cullinan diamond, which was cut to form the 530-carat Great Star of Africa.

The operation also yielded the 317-carat Second Star of Africa.

They are the two largest diamonds in the British Crown Jewels.

Cullinan is known as the world’s most important source of blue diamonds, such as the 39.34-carat stone Petra found in April and which sold for $40.2 million earlier this month. It was the company’s highest price ever for a single stone.

Blue rough diamond fetches $40 million


                39.3 carat blue rough diamond

Petra Diamonds Ltd. sold a 39.3-carat blue gem for more than $40 million, making it one of the most expensive rough diamonds ever.

The small miner sold the exceptional Type IIb blue diamond to a joint venture between top producer De Beers and Diacore, a trading company owned by the billionaire Steinmetz family, it said Monday. The stone fetched just over $1 million per carat and is the most expensive gem Petra has ever sold.

Petra found the diamond at the Cullinan mine in South Africa in April. The mine, once owned by De Beers, is famous for both large and blue stones and was where world’s biggest diamond was found in 1905. Blue stones are among the most rare and valuable.

The sale is good news for Petra, which was forced to restructure its debt last year, when the Covid-19 crisis brought the industry to a standstill at a time when the company was already facing a mountain of debt and falling diamond prices. The shares, which were once worth more than $1.5 billion, closed up 1.1% on Monday.

Petra puts “exceptional” 39-carat blue diamond up for sale


    39.34 carat blue diamond recovered by Petra                                         South Africa

South Africa’s Petra Diamonds has put a 39.34 carat Type IIb gem recovered at its iconic Cullinan mine in April up for sale, with viewings beginning June 15.

The company said the diamond of “exceptional quality” in terms of both its colour and clarity, will be showcased in Antwerp, Dubai, Hong Kong and New York.

Petra, which anticipates that the diamond will be sold via a special tender, said that biddings via its online platform will close on July 12.

While it didn’t set a price range for the stone, the miner said high-quality blue diamonds like the one for sale usually fetch the highest values.

Petra’s Blue Moon of Josephine diamond, cut from a 29 carat rough blue diamond, sold for $48.5 million in 2015.

The figure corresponds to a price of $4 million per carat, which remains the world record price per carat ever paid for a diamond.
