Collection of Blue Diamonds to Fetch Over $70M

Sotheby’s will sell a group of eight fancy-blue diamonds from De Beers across its global Magnificent Jewels auctions, expecting the set to bring in more than $70 million.

The stones are cut in various shapes and range from 1.22 to 11.29 carats, with a total weight of 32.09 carats, Sotheby’s said last week. The polished originates from five rough blues that De Beers and Switzerland-based manufacturer Diacore purchased jointly from Petra Diamonds in November 2020. Diacore cut and polished those stones into eight diamonds over the past two years.

Sotheby’s will offer three stones from the eight-piece group, called The De Beers Exceptional Blue Collection, this year. The first, a cushion brilliant-cut, 5.53-carat, fancy-vivid blue diamond will go under the hammer at the Magnificent Jewels and Noble Jewels sale in Geneva on November 9, with a high estimate of $15 million. Meanwhile, the December 7 Magnificent Jewels sale in New York will feature a cushion brilliant-cut, 3.24-carat, fancy-vivid blue, internally flawless diamond estimated at up to $8 million. That jewel will be joined by a cushion-cut, 2.08-carat, fancy-intense-blue diamond with an upper price tag of $1.5 million.

“I have remained in awe of the De Beers Exceptional Blue Collection since the first moments I set eyes on it,” said Olivier Wagner, head of Sotheby’s Magnificent Jewels auctions in Geneva. “The market for colored diamonds and precious gemstones has never been stronger. [The diamonds] will, I am sure, captivate all collectors of exceptional gemstones.”

Sotheby’s will sell the remaining five diamonds at its spring 2023 Magnificent Jewels auctions. Those include a step-cut, 11.29-carat, fancy-vivid-blue estimated at up to $50 million; a step-cut, 4.13-carat, fancy-intense-blue expected to go for up to $3.5 million; and a cushion brilliant-cut, 3.10-carat, fancy-vivid-blue diamond with a high price of $5 million.

In April, Sotheby’s sold another De Beers blue diamond: a step-cut, 15.10-carat, fancy-vivid-blue, internally flawless stone that went for $57.5 million in Hong Kong.

Petra Diamonds in Partnership Deal With Stargems on White And Blue Diamonds

*342.92 carat Type IIa white diamond: Petra Diamonds*

Petra Diamonds Limited has sold a 342.92 carat Type IIa white diamond and an 18.30 carat Type IIb blue diamond, both recovered at the Cullinan Diamond Mine in South Africa.

The stones have been sold into a partnership with Stargems (Pty) Ltd. Petra will receive an upfront payment of US$10.0 million for the 342.92 carat stone and US$3.5 million for the 18.30 carat stone, as well as retaining a 50% interest in the profit uplift of the polished proceeds of both diamonds, after costs.

Stargems is a Johannesburg-based subsidiary of Stargems Group, an international and vertically integrated diamond company, and is a diamond beneficiation licencee, allowing for the two diamonds to be cut and polished in South Africa.

Petra’s Chief Executive Officer Richard Duffy commented: “These two diamonds are wonderful examples of the very high quality and rare white and blue diamonds that are so well known from the Cullinan Diamond Mine. We are delighted that both stones will be manufactured in South Africa and it is fitting that we will be working with Stargems, who specialise in the sourcing and supply of the finest diamonds to customers across the world.”

Meanwhile, Shailesh Javeri, Chairman of Stargems Group, commented: “The stones will be beneficiated in South Africa at our Stargems cutting factory in Johannesburg and we look forward to working closely with Petra during the manufacturing process to reveal the eventual polished gems.”

Petra Diamonds finds 342-carat rough at Cullinan mine

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

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 sells 299 carat diamond for $12.18 million

299.3-carat, type 11a, white gem-quality diamond

Petra Diamonds has sold a 299.3 carat diamond recovered in January at its iconic Cullinan mine, in South Africa, to Belgium-based Stargems DMCC for $12.18 million.

The exceptional Type 11a white gem-quality rock achieved a price of $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.

The freshly sold find adds to other most famous diamonds unearthed at Cullinan, such as “The Blue Moon of Josephine”. This 29.6 carat blue diamond sold for $48.5 million in 2015, a world record price per carat for any diamond sold at an auction at the time.

The company’s board approved such reorganization in January, and Petra expects to finish the process around the end of March.

Petra’s shares slumped by more than 80% last year as the covid-19 pandemic battered the global diamond sector, with mines forced to shut down while consumer demand continued to fall.

De Beers Buys Petra Blue Diamonds for $40M

De Beers has purchased five rough blue diamonds from Petra Diamonds for more than $40 million in partnership with one of its sightholders.

The miner bought the Letlapa Tala collection together with South African wholesaler and manufacturer Diacore for $40.4 million, split equally between the two companies. The type IIb stones, which originated from Petra’s Cullinan mine in South Africa, weigh a total of 85.6 carats, with the individual diamonds ranging from 9.61 to 25.75 carats, Petra said Wednesday.

The sale price at the November 24 tender exceeded analysts’ predictions. Liberum believed the stones would fetch “in the region of $30 million to $40 million,” while Berenberg predicted approximately $26 million, they told Rapaport News.

“The result of this special tender affirms the very high value placed on blue diamonds,” said Petra CEO Richard Duffy. “We believe this to be the first time that five rough blue diamonds of significant size, color and clarity have been offered for sale at one time, and we are delighted that the collection has been bought in its entirety.”

Diacore, which specializes in manufacturing rare, fancy-color diamonds, has worked with De Beers before. It previously cut the miner’s 203.04-carat De Beers Millennium Star, and has also worked on other well-known stones, such as the CTF Pink Star, a 59.60-carat pink bought by Hong Kong jeweler Chow Tai Fook for $71.2 million in 2017. The manufacturer, with cutting facilities in Botswana, South Africa and Namibia, was also one of the pilot participants in De Beers’ Tracr blockchain initiative.

“We are excited and humbled to have the opportunity to unlock the unparalleled beauty of these rare and extraordinary natural diamonds and share them with the world,” said Paul Rowley, executive vice president of diamond trading at De Beers. “Cullinan has produced some of the most beautiful diamonds the world has ever seen, and these blue diamonds are no exception.”

De Beers and Diacore will select expert craftsmen to study and work with the diamonds before presenting them to the public, De Beers added.

De Beers previously owned the Cullinan mine. It sold the deposit to Petra for $149 million in 2007.

Rare Rough Blue Diamonds

Recovered from the famous Cullinan Mine in South Africa, these blue diamonds are among the world’s most expensive

Five blue diamonds have been recovered from Petra Diamonds’ famous Cullinan mine in South Africa.

They are among the world’s most expensive diamonds, and were formed deep within the Earth about 400 miles below the surface, which is four times as deep as white diamonds. The element boron, which is what gives the stones their blue colour, combines with carbon and crystallises under extreme pressure and heat.

The sales tender for the five Type IIb blue diamonds will close later this month, on November 24, following viewings in Antwerp, Hong Kong and New York. They weigh 25.75, 21.25, 17.57, 11.42 and 9.61 carats, respectively.

Type II diamonds contain no detectable nitrogen in their chemical structure, which means they boast exceptional transparency.

Blue diamonds are so rare that most people, even in the jewellery industry, never have a chance to see one. It’s incredibly unusual that these five diamonds were all recovered within the space of one week’s production in September.

Their birthplace, the Cullinan mine, is one of the most important sources of blue diamonds. It’s also the origin of the 3,106 carat Cullinan diamond, which was cut to form the 530 carat Great Star of Africa and the 317 carat Second Star of Africa, which are set into the British Crown Jewels.

It’s the first time that five rough blue diamonds have been offered for sale at the same time. In 2013, a 25.5 carat blue diamond was sold by Petra Diamonds for over US$16.9 million.

Petra to sell blue diamonds recovered at Cullinan

A 20.08-carat Type IIb blue diamond recovered at Cullinan.

Petra Diamonds (LON: PDL) announced the launching of a special tender process for the Letlapa Tala Collection, which comprises five blue diamonds sourced from the Cullinan mine in South Africa.

Cullinan is known as the world’s most important source of blue diamonds, as well as being the place of birth of the 3,106-carat Cullinan diamond, which was cut to form the 530-carat Great Star of Africa and the 317-carat Second Star of Africa, being the two largest diamonds in the British Crown Jewels.

In a press release, Petra said that the name of the new collection actually means ‘blue rock’ in Northern Sotho (commonly known as Pedi), the predominant language spoken in the Cullinan area.

CULLINAN IS KNOWN AS THE WORLD’S MOST IMPORTANT SOURCE OF BLUE DIAMONDS

The collection consists of five Type IIb blue diamonds of 25.75, 21.25, 17.57, 11.42 and 9.61 carats, respectively. Type II diamonds contain no detectable nitrogen in their chemical structure and tend to display exceptional transparency. Type IIb stones contain a small amount of boron, which is what determines their blue colour.

“Blue diamonds are so rare that most people working in the diamond industry have never even seen one,” the media release states. “There are no official statistics on their recovery, so it is therefore even more unusual that these five spectacular stones were all recovered within the space of one week’s production in September 2020.”

According to Petra, this is likely to be the first time that five blue rough diamonds have ever been offered for sale at one time, with buyers being offered the chance to bid either on individual stones, more than one, or for the entire collection.

The Letlapa Tala gems will be available for viewings in Antwerp from October 25 to November 1; Hong Kong from November 5 to November 10; and New York from November 16 to November 20, 2020.

Petra Diamonds shares fall on debt for equity deal

Petra Diamonds has abandoned plans to sell the business in favour of a debt-for-equity restructuring, it said on Tuesday, sending its shares lower because of the deal’s dilutive effect on existing stakeholders.

The London-listed company, which mines diamonds in South Africa and Tanzania, had put itself up for sale in June as part of the restructuring process but has received no viable offers, it said.

Its shares have slumped by more than 80% this year as the COVID-19 pandemic has battered the global diamond sector, with mines forced to shut down while consumer demand collapsed. The shares opened with an 18% drop and by 0952 GMT were down 3.6%.

Petra said its existing $650 million of bond debt will be partly replaced by up to $337 million of new notes, including $30 million of new money contributed by debtholders.

The remaining note debt will be converted into equity, leaving debtholders with a combined 91% of the company while diluting existing shareholders to a combined stake of only 9%.

“For existing equity holders it is very dilutive, as expected,” wrote Liberum analyst Ben Davis.

Existing shareholders will be diluted to “next to nothing”, Shore Capital analysts wrote.

Peel Hunt analysts took a more optimistic view, saying the restructuring would give Petra a more sustainable balance sheet and help it to benefit from a recovery in markets for rough diamonds. They calculated that Petra would be left with $444 million of gross debt.

Petra said it expects to seal a “lock-up agreement” cementing the terms with the noteholder group and South African lenders in early November. It expects the restructuring to become effective in the first quarter of 2021.

The agreement also includes new governance arrangements and cashflow controls.

Petra Chief Executive Richard Duffy expressed the company’s gratitude to the noteholder group and South African lenders for their agreement in principle to provide “meaningful additional liquidity” in what has been a difficult period.

Petra Diamonds recovers five rare large high-quality blue diamonds at Cullinan Mine

South Africa’s Petra Diamonds, which put itself up for sale in June, announced on Wednesday it had found five high-quality blue diamonds, but toned down the news by saying the discovery won’t help turn around its fortunes.

Petra, which has been hit by a triple whammy of weak market conditions, power emergencies in the home country and covid-19, found the Type IIb blue diamonds at its flagship Cullinan mine.

The high quality stones, in terms of both their colour and clarity, range in size from 9.6 carats to 25.8 carats, the company said.

The miner didn’t indicate the diamonds’ potential value but said it is considering sale options.

“These finds, whilst a positive development, will not have a material impact on the likely terms of the required long-term solution to improve the group’s capital structure, nor the significant level of equity dilution that existing shareholders are likely to experience in connection with its implementation,” Petra said in the statement.

The company also warned that measures to improve its capital structure could result in significant equity dilution.

Blue stones are among the rarest and most valuable and have lately fetched higher prices than white diamonds. Last year, Petra sold a 20.08-carat blue gem for $14.9 million, or about $741,000 per carat.

“Flexible” approach to sales
Petra was already struggling when the covid-19 pandemic added further pressure to a sector that was just beginning to show some green shots.

The miner tried in 2019 to turn around its fortunes after piling up debt to expand its flagship Cullinan mine in South Africa. The renowned mine, where the world’s largest-ever diamond was found in 1905, produces about a quarter of the world’s gem-quality diamonds. It is also the source of the vast majority of blue stones.

In May, Petra failed to make an interest payment on a $650 million bond, but won some breathing space from creditors who said they would not declare a default until August.

The diamond producer also cancelled May and June tenders because of travel restrictions and low demand from the midstream. While it originally expected to hold a tender in September, Petra said it was still evaluating the optimal route to market for the stones it mines. It added it would release further information to its customer base once a decision about the marketing plan to follow had been made.

For now, the company is taking a “flexible” approach to selling diamonds in light of ongoing travel restrictions triggered by the global pandemic.

Despite the numerous challenges, Petra is targeting a ramp-up to pre-covid-19 production levels. It added it will disclose production targets for 2021 once it reaches a “sustainable level of operational stability.”
