Botswana Diamonds acquires Sekaka from embattled Petra

 

Botswana Diamonds (LON:BOD) said on Monday it had completed the acquisition of Sekaka, the exploration vehicle that belonged to embattled rival Petra Diamonds (LON:PDL) and which held three prospecting licenses in the country’s Central Kalahari Game Reserve.

In one of its licenses, Sekaka had singled out the KX36 kimberlite pipe, which is situated about 70 km from Gem Diamonds’ Ghaghoo mine, and 260 km north-west of Botswana’s capital Gaborone.

SIGN UP FOR THE PRECIOUS METALS DIGEST
Sekaka also had a recently built, fit-for-purpose bulk sampling plant on-site that includes crushing, scrubbing, dense media separation circuits and X-ray recovery modules within a secured area.

The acquisition includes an extensive database, built up over 15 years of exploration.

Botswana Diamonds believes the information contained in the database will provide substantial support to its future kimberlite exploration activities in the mining-dependent country, the world’s second-largest diamond producer.

“We are delighted that this acquisition has now closed. This paves the way to explore commercial development options for KX36 and begin to evaluate the extensive database in conjunction with ours to discover more kimberlites in prime diamond real estate,” chairperson John Teeling said in a media statement.

Diamond exports from the southern African nation dropped 42% to $1.49 billion in the first nine months of this year as production fell 29% to 12.3 million carats due to covid-related restrictions.

Botswana’s mining sector provides a fifth of the country’s GDP and 80% of its foreign exchange earnings.

Mounting woes
Petra Diamonds, the former owner of Sekaka, has been struggling for over two years. Its weak financial position pushed it to shed non-core assets and put itself up for sale in June.

The company reversed the decision in October, opting instead for a debt-for-equity restructuring. The deal would leave existing shareholders with just 9% of the company.

Petra is also dealing with allegations of human rights abuses at its Williamson mine in Tanzania, resulting from the actions of its security guards.

It recently reported a 36% fall in revenue and a net loss of $223 million (168.7 million pounds) for the year ended June 30, as the coronavirus pandemic deepened the company’s financial woes.

Gem Diamonds Unearths 179ct. Rough

 

Gem Diamonds has recovered a 179 carat rough diamond from its Letšeng mine in Lesotho.

The miner found the high quality, type I diamond on Thanksgiving Day, it said last week. The stone is the 16th diamond over 100 carats the company has found this year. Earlier this month, Gem Diamonds unearthed 104 and 111 carat specimens from the deposit.

The company has already found more diamonds over 100 carats this year than in 2019, when it reported 11 rough diamonds of that magnitude.

Letšeng also yielded a 14.09 carat, pink, type II diamond of high quality last week from its mine in Lesotho.

The miner unearthed the “top quality” type II stone from the deposit on November 24, it said Wednesday. The discovery comes after the company found a 77 carat yellow diamond at the mine in September.

Gem Diamonds has also found 14 diamonds weighing over 100 carats this year, including 104 and 111 carat diamonds earlier this month.

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.

Largest ever CVD laboratory-grown diamond hailed a “remarkable achievement”

 

The International Gemological Institute’s (IGI) Hong Kong laboratory has certified the largest chemical vapor deposition (CVD) laboratory-grown diamond received to date.

With a finished weight of 12.75 carats, this collection-quality man-made gemstone was fashioned from a 46.20 carat CVD-grown rough crystal.

According to its creator, Shanghai Zhengshi Technology, it is the largest CVD lab-grown diamond ever produced.

“For the past 15 years, IGI has been at the forefront of lab-grown certification and education,” stated IGI CEO, Roland Lorie. “With this milestone, the Institute continues to establish itself as the prominent leader in the industry and opens the door for future opportunities to exceed current gemological standards.”

IGI gemologists confirmed the 12.75ct stone was Type IIa, giving it exceptional chemical purity and transparency, with VVS2 clarity, F color, and triple-excellent marks in cut-quality and finish.

Following detailed scientific analysis, the laboratory substantiated that the stone had not undergone any post-growth treatments, so it can be categorised as a pure CVD diamond.

“A laboratory-grown diamond of this carat weight, with such a high clarity and color grade, is a remarkable achievement in CVD cultivated diamond technology,” said IGI Hong Kong managing director, Bob Van Es. “As the industry leader in the certification of laboratory-grown diamonds, IGI will continue to follow these new developments closely.”

This news comes only three months after the IGI analysed the Guinness World Record-holding biggest black lab-grown diamond.

Synova’s Automated Cutter to Tackle Fancy Shapes

 

Swiss technology provider Synova has expanded its automated diamond-cutting system to include fancy shapes, it said Monday. 

The company, which is part-owned by De Beers, unveiled the DaVinci Diamond Factory last year at the Dubai Diamond Conference. Synova claims the machine will significantly speed up diamond manufacturing from weeks to hours, improve accuracy and symmetry, and reduce costs. However, the version it initially launched could only cut round-brilliant diamonds with up to 57 facets.

“The pandemic restrictions had us more or less blocked from selling in the first half, so instead of sitting here and doing nothing, we developed the machine and made it market-ready,” Joerg Pausch, head of the diamond business at Synova, told Rapaport News. “We developed software add-ons that will allow for cutting of automated fancy shapes. After the first announcement, people were calling us asking if it can do fancy shapes, and that has actually become our strongest request from the market.”

Synova’s initial testing of the automated fancy shapes has shown “very promising results,” it noted. The technology provider will release the new software early next year.

The company has already received a number of orders for the DaVinci from Europe, South Africa and North America, Pausch noted. It also intends to develop the machines to include more automation, he added.

Luminous Diamonds’ Debut Collection Celebrates Your Inner Glow

 

The new fine jewelry company is a leader in rare fluorescent stones.

All diamonds shimmer when light hits them. Under master hands, they are cut into interesting shapes that spark joy. Gems from Luminous Diamonds, a new fine jewelry brand, however, have an attribute that many precious stones don’t: They glow.

Luminous Diamonds’ parent company, Alrosa, is a leader in sourcing fluorescent stones, which are formed under unique geological conditions that leave trace elements during the carbon crystallization process. As a result, Luminous Diamonds shine extra bright in the sun and, most intriguingly, emit a blue glow under UV light.

“These diamonds are stunning, luminous, and make a statement,” says Rebecca Foerster, Alrosa’s president of North America. “They reflect the way modern women wear confidence like a rare jewel, and they dare us all to stand out by sharing our inner selves. Greatness in people, like diamonds, is made under pressure. When a woman follows her own inner light, others see it. Our diamonds are an enduring reminder of this light.”

To highlight this point, Luminous Diamonds enlisted female leaders from disparate industries to model its debut collection in a campaign titled Greatness Under Pressure. They are WNBA athlete Skylar Diggins-Smith, attorney and travel writer Cynthia Andrew, violinist Ezinma Ramsay, gender-fluid advocate Elliott Sailors, model Denise Bidot, and photographer Marian Moneymaker.

The 28-piece collection consists of brilliants and pavé diamonds on open-work hexagon settings. They include long necklaces with pendants, crawler and chandelier earrings, and bracelets. Each design comes with an illuminator charm that emits UV light so you can get that inner glow all the time.

De Beers sales rise 12% as diamond demand recovers

 

De Beers Group announced on Wednesday that sales of rough diamonds rose more than 12% in the latest sales cycle, as demand improves on the back of easing covid-19 restrictions and ahead of the holiday season.

Sales of $450 million between November 2 and November 16 were higher than the $400 million a year earlier, but declined from the $467 million in the eighth cycle between September 21 and October 9.

SIGN UP FOR THE PRECIOUS METALS DIGEST
“Steady demand for rough diamonds continued in the ninth sales cycle of the year, reflecting stable consumer demand for diamond jewellery at the retail level in the US and China, and expectations for reasonable demand to continue throughout the holiday season,” De Beers CEO Bruce Cleaver said in a media release.

“However, the resurgence of covid-19 infections in several consumer markets presents ongoing risks.”

The company has continued to implement a more flexible approach to sales during the year, as a result of restrictions triggered by the pandemic.

It has also cut prices of its stones, sometimes by almost 10% for larger diamonds, in an effort to spark sales.

On Tuesday, rival Petra Diamond Petra reported a 36% fall in revenue and a net loss of $223 million for the year ended June 30, as the pandemic deepened the company’s financial woes.

Germany diamond robbery: thieves who cleaned 1 billion euros of diamonds

 

A year ago, three people caused the theft of € 1 billion diamonds in Germany. One of these diamonds was encrusted in a 16th century sword. Police raided apartments in Berlin in the morning and arrested three suspects suspected of theft at the Green Vault Museum last year. Police searched 18 apartments, garages and vehicles and seized digital data, clothing and tools.

Arrest in different parts of the country
It was an operation of such magnitude that 1,638 officers were involved, which hampered traffic. Three people from Germany have been arrested and will be brought before a judge. Force said the arrests were made in different parts of the country. However, little information has been given on this subject. Security camera footage showed two people breaking into the museum and entering a window grill.

Includes many diamonds
One of the stolen items was a sword that contained 9 large diamonds and 770 small diamonds. At the same time, the 49-carat Dresden white diamonds were worn on the shoulder. These are among the most valuable gems that were included in the collection of the former ruler August the Strong. Police say thieves may have turned off alarm systems by cutting off the power.

Difficult to assess
Museum director Marion Ackerman said last year that the material used in the jewelry was not very valuable, but overall it was worth more. He said that these gems are a treasure trove of art and culture and that it is difficult to assess them. Another director of the museum, Dirk Syndrum, said that these decorations were in some way equivalent to World Heritage. In addition to diamonds, sapphires, rubies and emeralds were also among the stolen sets, he said.

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.

Pink Diamond Ring Beats Estimate at Bonhams

 

A fancy pink diamond ring by Meister was the top seller at the Bonhams London Jewels sale, garnering $1.1 million USD.

The piece, with a step-cut 3.62 carat center stone and designed in 1968 by Meister, exceeded its high estimate of $989,417 USD at the November 12 auction, Bonhams said last week. 

A diamond brooch from the collection of Dame Joan Collins, designed by Van Cleef & Arpels, fetched $161,892 USD, more than six times its high valuation. It was part of a collection of the actress’s jewels that saw 100% of items find buyers, with the final sales total three times higher than the auctioneer had estimated. A portion of the proceeds from Collins’s jewelry will be donated to the Shooting Star Children’s Hospice, of which she is a patron.

Other notable items at the auction included a sapphire and diamond ring, which fetched $189,865 USD against a high estimate of $131,851 USD, and a three-stone diamond ring, which brought in $132,179 USD, nearly doubling its estimate.

In total, the auction achieved $5 million USD, with Bonhams selling 75% of items on offer.

“Despite the auction taking place behind closed doors, the bidding remained spirited and the results demonstrate that high quality pieces with extraordinary provenance continue to captivate buyers around the world,” said Jean Ghika, global head of jewelry for Bonhams.

$27M Pink Diamond Sets Record at Sotheby’s

 

Alrosa’s Spirit of the Rose has achieved the highest price for any purple-pink diamond, selling to an anonymous bidder for nearly $27 million at Sotheby’s Geneva.

The oval modified brilliant-cut, 14.83-carat, fancy-vivid-purple-pink, internally flawless, type II stone, named for the famous Russian ballet, sold for $26.6 million, beating its low estimate of $23 million. The diamond, which fetched $1.8 million per carat, led the Magnificent Jewels and Noble Jewels live auction Wednesday, which garnered $52.2 million in total, Sotheby’s said.

The purchase comes on the heels of the recent closure of Rio Tinto’s Argyle mine in Australia, which produced more than 90% of the world’s pink diamonds. Prices for stones of that color are likely to soar in the coming years, experts have noted.

“The Spirit of the Rose caught the imagination of everyone who had the chance to see it,” said Benoit Repellin, head of the Sotheby’s Geneva Magnificent Jewels auction. “With its size, beautiful color, perfect cut and oval shape, it is a wonder of nature, steeped in Russia’s century-long diamond tradition and cultural heritage. It fully deserves the price achieved tonight, which is also testament to the growing appreciation and awareness of the great scarcity of pink diamonds around the world.”

Sotheby’s also saw strong prices for white diamonds at the auction, with 10 out of 11 stones on offer selling above their estimates. A cushion-shaped, 18.03-carat, D-color, flawless, type IIa diamond fetched $1.9 million against a high estimate of $1.1 million, while a pear-shaped, 102.41-carat, light-brown diamond of VVS2 clarity brought in $1.3 million, exceeding its high valuation.

Noble jewels were in demand as well, Sotheby’s said, led by a Colombian emerald and diamond parure from the collection of the first Marquis de Guirior, viceroy of New Granada and viceroy of Peru. That piece also surpassed its high estimate, fetching $1.1 million.
