Sarine is introducing a traceability solution for melee diamonds.
The Israel-based diamond tech company is expanding its existing technology to cover the smaller stones (generally under 0.2-cts) widely used in jewelry settings.
“To guarantee responsible sourcing of melee and enhance consumer confidence, we specifically aim to enhance the certainty regarding the diamonds’ provenance, by establishing a verifiable documented link between the rough diamonds and their origin and the polished stones used in the jewellery piece,” the company said.
Sarine partnered with the high-end French jeweler Rubel & Menasche, to develop and test its new, data-backed verifiable traceability system, which scales up its tried and tested Journey technology to handle large quantities of small stones. Parcels are initially registered on the Autoscan Plus system.
Rubel & Menasche described the new technology as an “important milestone”. David Block, Sarine’s CEO, said: “This initiative reaffirms our commitment to a more transparent diamond industry.”
Indian mining billionaire Harpal Randhawa, his son, and four others died when their plane crashed en route to the Murowa diamond mine, in Zimbabwe.
The Cessna 206 aircraft belonged to Randhawa’s RZM Murowa, a company that part-owns and operates the mine. It also produces gold and coal and refines nickel and copper.
Randhawa and his 22-year-old son Amer set off from Harare on Friday morning (29 September). Their plane came down in the southwestern part of the country, reportedly due a technical fault.
Zimbabwe police said the crash happened between 7.30 am and 8am, and confirmed the deaths of all six people on board.
“The Murowa Diamond Company (RioZim)-owned white and red Zcam aircraft had left Harare for the mine at 6 am and crashed about 6 km from Mashava,” it said.
Planes are often used as a secure method of transporting diamonds. In February a light aircraft transporting diamonds from Murowa came down in a field, also after experiencing technical problems.
The pilot suffered head injuries and was said to be in a critical condition. Four passengers were in a stable condition.
Revenue from the Ekati mine’s rough output climbed 11% during the third quarter, according to owner Burgundy Diamond Mines.
The company sold 784,000 carats of rough from the Canadian deposit for $90 million in total between July 1 and September 13 up from 901,000 carats for $81 million a year earlier. Burgundy reported these figures last month as sales-to-date for the quarter, which ended September 30.
“The sales results…demonstrate the differentiated value of Burgundy diamonds and our transparent and credible sales channels, despite a softer-than-usual market,” said Burgundy CEO Kim Truter.
Burgundy purchased Ekati from Arctic Canadian Diamond Company for $136 million in March. At the same time, it chose not to pursue its options at the Ellendale mine in Australia, of which it had considered taking ownership.
Burgundy had approximately $139 million in rough inventory at the end of August, in addition to its ongoing diamond production, it noted in the September statement.
The company’s shares rose 16% on the Australian Stock Exchange (ASX) following the announcement.
Anglo American Plc unit De Beers and Botswana’s government signed a deal covering the main aspects of a new sales and mining agreement for their Debswana diamond venture in the African nation.
The pact covers a new 10-year sales deal for Debswana’s rough diamond production through to 2033, along with a 25-year extension to the Debswana mining licenses through to 2054, De Beers and the Botswana government said in a joint statement on Sunday.
The terms “provide further detail and clarity to the commercial and operational aspects of the agreement in principle between the two partners” announced on June 30, they said. Among them are stipulations for the apportionment of Debswana supply and other economic arrangements, they said, without giving further details.
Western officials are expected to head to India this week to discuss the technical aspects of a coming G7 ban on Russian diamonds as they come closer to finalising a sanctions package that may kick in as early as January 1.
But sanctions experts have warned that negotiations may drag on past the expected deadline due to the complexity of enforcing a widely accepted mechanism to trace the origin of diamonds.
“If this mechanism is understandable and transparent enough from the beginning, then there are high chances that all G7 countries will sign off on it,” Yuliia Pavytska, who heads the sanctions team at the KSE Institute, a Kyiv School of Economics-affiliated think tank, told The National.
“If there is no agreement in the coming weeks, it will likely take a few more months to make it happen.”
The impact of a ban on the Russian economy would be relatively small but not insignificant.
Russia’s diamond exports account for about $4 billion – or about 1 per cent – of the country’s total exports, according to Ms Pavytska.
But with half of Russia’s exports comprising oil and gas, diamonds are one of the largest trade groups that have yet to be sanctioned.
“There’s been talk for months about a diamonds ban, and now we finally see that the G7 is ready to discuss it and adopt it,” she said.
Belgium has long resisted a ban on Russian diamonds due to their importance for its second-largest city, Antwerp, the largest diamond hub in the world.
But it has recently put forward a proposal that is garnering support among the G7, which may finalise its proposal in the coming weeks. This would be followed by an implementation of the ban at the EU level next year.
As discussions intensify, western officials are expected to travel later this week to India, the world’s diamond-polishing hub, for what EU authorities have described as a fact-finding mission organised by the Indian Gem and Jewellery Export Promotion Council.
Speaking to Reuters last week, US officials said that he delegation would travel to Mumbai and Surat, a city where about 80 per cent of the world’s diamonds are polished.
Belgian officials will reportedly be part of the delegation.
Belgium’s proposal Belgium is not a member of the G7 but is part of the EU, which is represented in the forum that also includes the US, the UK, Canada, France, Germany, Japan and Italy.
The US, the UK and Canada have already banned Russian diamond imports in various ways.
Belgium argues that an outright G7 ban would encourage circumvention, pointing to the fact that while imports of Russian diamonds to the EU have decreased by 95 per cent from pre-war levels, the number of diamonds being traded in Antwerp has not significantly changed.
These figures have fuelled suspicion that Russian diamonds are changing identity before entering western markets.
Experts such as Agiya Zagrebelska, who heads the sanctions direction at the Ukrainian National Agency on Corruption Prevention, said that there has been an increase in purchases of Russian diamonds from companies based in major trade hubs including India and the UAE.
“What is being sold on western markets are Russian diamonds because it’s impossible that the diamonds traded by these companies come out of nowhere,” Ms Zagrebelska told The National.
The Belgian diamond industry has called for the creation of an improved system to track diamonds – a notoriously difficult process.
Rough diamonds are split before they are polished and then possibly mixed with other diamonds.
The proposal focuses on reinforcing traditional customs inspections with blockchain technology to create a ledger that is impossible to forge.
The aim is to cut Russian diamonds off from the G7 market, which represents more than 75 per cent of the diamond consumer market, and forcibly drive their price down.
“The ban on Russian diamonds will not only reduce the revenue Russia is extracting from the export of diamonds but will simultaneously increase the traceability of diamonds at a global level, which has been a long-standing EU policy ask,” an EU official said.
There are other proposals reportedly under discussion, but the diamond lobby has remained tight-lipped about them.
“We understand that it all depends on what trace and track system the G7 countries will choose,” said Ms Zagrebelska.
The Antwerp World Diamond Centre declined to comment when contacted by The National.
The US-based World Diamond Council did not answer a request for comment.
Alrosa has canceled its next two sales and urged caution from buyers and suppliers amid a steep downturn in the diamond market.
The Russian miner informed India’s Gem & Jewellery Export Promotion Council (GJEPC) of the decision in the past few days, citing low demand. The move follows the GJEPC’s recent call for rough producers to act responsibly.
“Alrosa has decided to temporarily halt the allocation of rough diamonds in September and October 2023,” the company said in a note to the GJEPC, seen by Rapaport News. “We believe that this approach is going to have a stabilizing impact by strengthening the market’s supply-and-demand balance. This will aid the prevention of overstocking, especially with manufacturers closed for Diwali.”
Alrosa has continued to sell despite being under US sanctions since the Ukraine war began in February. The company’s revenue was broadly stable year on year at RUB 188.16 billion ($1.9 billion) in the first half of 2023.
Most of the rough goes to India, market insiders believe. That country’s diamond trade has suffered a serious crisis because of weak US and Chinese demand and competition from lab-grown stones. Inventories have piled up as the sales slump has outpaced manufacturers’ production cuts, leading to falling prices.
The GJEPC wrote to diamond miners earlier this month, asking them to be “responsible” when selling to prevent a worsening of the situation. In response, Alrosa said it “expresses equal concern and strives to reverse the existing trend of diminishing demand.”
The Russian company said it would welcome a similar position from other industry players, such as miners, cutters and retailers, “on the matter of rough-diamond purchases and sales” as a “reciprocal effort.”
The benefits of the miner’s decision should be visible in the market by the beginning of next year, it said in a separate statement Wednesday.
“Alrosa has always followed the practice of supporting market stability and leveling its volatility,” a spokesperson for the miner said. “Our solid and high-quality asset base and stable financial position allow us [to implement] such measures.”
By contrast, De Beers will continue to hold sights but take a “responsible approach” to sales, “just as we have previously when faced with challenging industry conditions,” a spokesperson for the Anglo American unit said. The company, which is holding its September sight this week, has already allowed customers to defer up to half of rough purchases for the rest of 2023.
“We will focus on additional supply flexibility as necessary to meet sightholders’ evolving requirements,” the De Beers spokesperson added.
The news comes amid growing expectations for a Group of Seven (G7) ban on Russian diamonds, with an announcement likely in two to three weeks, Reuters reported last Friday, citing Belgian officials. The World Diamond Council (WDC) is also facilitating a proposal for keeping Russian and non-Russian diamonds separate.
Western Australia’s Argyle mine was among nature’s preeminent treasure troves for nearly 40 years. At its peak, Argyle produced more coloured diamonds than anywhere else on Earth and earned an especially sparkling reputation for its unparalleled cache of pink diamonds.
Researchers have spent decades trying to unravel the origins of Argyle’s glimmering gems. Now, by dating minerals in the mine’s volcanic rock, scientists think they may have finally pieced together the process that created the deposit around 1.3 billion years ago. In a paper published on Tuesday in Nature Communications, the team posits that the breakup of an early supercontinent lifted Argyle’s salmon-coloured stones from crushing depths toward Earth’s surface.
Located 2,200 kilometers northeast of Perth, Australia, in the country’s rugged Kimberley region, Argyle mine once covered an area the size of 94 football fields. Between its opening in 1983 and closure in 2020, when mining the gems there was no longer economically viable, Argyle produced more than 865 million carats of rough diamonds. Most of these stones come in pale shades of yellow or brown. But a small percentage of the site’s diamonds radiate rich pinks, purples or reds. More than 90 percent of the world’s pink diamond supply including the nearly 13 carat Pink Jubilee has come from Argyle.
The pink hue of Argyle’s most lavish diamonds is linked to damage they underwent deep within the earth. According to Hugo Olierook, a geologist at Curtin University in Perth and lead author of the new study, these diamonds start out colourless. But immense tectonic pressure from colliding continents can alter the stones’ crystal structure, unlocking the potential colours hidden within. “The diamonds are being forced to bend and twist,” Olierook says. “If they’re twisted just a little bit, it will turn some of these diamonds pink.” Further twisting makes them become brown.
Argyle’s diamonds took on their pink and brown tints around 1.8 billion years ago, when a piece of what is now western Australia smashed into the northern Australian plate and warped the region’s rock. But this only explains part of Argyle’s origin story. When the continents collided, the area’s diamonds were buried in the mantle, hundreds of kilometers below Earth’s surface. If the crystals had been closer to the surface, their carbon atoms would have been compressed into a different structure, transforming them from shimmering diamonds to lumps of dark gray graphite.
A volcano was necessary to bring the molten diamonds up from our planet’s mantle. “You need some sort of tectonic trigger to bring them up to the surface,” Olierook says. As the melt rises, carbon dioxide and steam expand, sparking an eruption that he compares to popping a champagne cork. At Argyle, this eruption likely occurred at a beach, where sand and seawater interacted with volcanic rock called lamproite.
To determine when the eruption occurred, the team sliced two thin sections of Argyle’s volcanic rock and polished them down to a minuscule width. Analyzing the sample’s mineral makeup under a microscope, the researchers were able to pinpoint sand grains from Argyle’s ancient beach and to date them with the help of radioactive elements they contained. By dating the youngest sand grains, the scientists were able to estimate when the beach was buried in lava. They also used tiny lasers to determine the ages of titanite minerals, which formed in the rock when the magma melded with quartz in the beach sand.
Comparing the ages of the youngest sand grains and the oldest titanite crystals allowed the researchers to estimate that the eruption at Argyle occurred between 1.3 billion and 1.26 billion years ago. This age range was older than previous estimates, which surprised Olierook and his colleagues. “We had a betting pool going, and nobody got 1,300 million years,” he says. “That was one of those glass shattering moments.”
That eruption timing corresponds to a volatile period in Earth’s tectonic history when one of the first supercontinents, called Nuna, was splintering apart. The team posits that this instability may have reopened a seam along the continental boundary where Argyle is now situated. This in turn sparked the volcanic activity that brought the diamond-bearing melt toward the surface, creating Argyle’s expansive diamond deposits.
The new time estimates add crucial context for understanding the volcanic eruption at Argyle, says Evan Smith, a researcher at the Gemological Institute of America, who researches the geology of diamonds but was not involved in the new study. “The previous age constraint for Argyle was younger, and it was a lot less clear how to frame the eruption in a broader geological context,” Smith says. He thinks the new study adds exciting evidence that these “eruptions are related to bigger processes that affect whole continents rather than being isolated, random burps of magma.”
Olierook thinks similar events may have occurred at other continental boundaries around the world. Most diamond-bearing deposits are found in the middle of continental plates where rock is exposed. This makes Argyle an outlier. When the mine was first discovered, most geologists thought that searching for diamonds along continental plate boundaries which are often uplifted by ancient mountain belts and buried beneath soil and sand was futile.
Though gem mining in these regions remains difficult, Olierook believes there are plenty of diamonds to be found in the rough. “I think all of them will host some sort of coloured diamonds,” he says. “They may all be brown, but with a little bit of luck, there could be a few pinks in there.”
Diamond processor and trader HB Antwerp said on Monday it had removed one of its three co-founders from management following differences over strategy, a development that comes amid a pending sales pact with major producer Botswana.
Oded Mansori, who co-founded HB Antwerp in 2020 with partners Shai de Toledo and Rafael Papismedov, said he was taking them to court over his removal.
“On September 1, HB terminated Mr Oded Mansori’s management role in all the HB Companies,” the Belgian company said in a statement, citing a “sharp difference in strategic vision and approaches to business”.
The government of Botswana, the world’s No. 1 diamond producer by value, said in March that it had agreed to buy a 24% stake in HB Antwerp. As part of the deal, state-owned Okavango Diamond Company would supply HB with an undisclosed quantity of rough diamonds for five years.
The deal is yet to be signed.
Mansori, a long-time diamond dealer, said in a separate statement that he was “determined to defend his vision and to fight for the wellbeing and the future of HB,” and that “a legal process is currently underway in court.”
Mansori, who declined to comment further, said he was still a shareholder in the company.
HB also has a partnership with Lucara Diamond Corp, buying stones of 10 carat quality and above from the Toronto-listed miner’s Karowe Mine in central Botswana at prices based on the estimated polished outcome of each diamond.
Lucara did not immediately respond to a request for comment on whether the legal tussle could impact its own deal with HB Antwerp.
In 2022, HB Antwerp partnered with Microsoft to track mined gems via blockchain, as consumers focus on clearing the supply chain of fraudsters and diamonds mined in war zones and sold to fund insurgencies.
Other diamond miners, including Anglo American’s unit De Beers, also use blockchain platforms to trace their diamonds and verify authenticity.
Sanctions-hit Alrosa, the world’s biggest diamond-producing company, said on Sunday it has mined the largest gem-quality diamond in Russia in the past decade.
The 390.7-carat diamond was mined at one of the company’s mines in the Republic of Sakha, Alrosa said in a statement. The region, commonly known as Yakutia, lies in Russia’s Far East along the Arctic Ocean.
“The found diamond is a light crystal of an irregular shape, bordered by a yellow-brown halo – a combination of mass, shape and colour that is unique today,” Alrosa said.
The company mined the largest gem-quality diamond in Russia in 2013, weighing 401 carats, Alrosa said.
The world’s largest gem-quality diamond ever mined – the 3,106-carat Cullinan stone – was recovered in South Africa in 1905.
Alrosa was last year placed under sanctions by the United States, which cut it off from its banking system and banned direct sales to the US market after Russia invaded Ukraine.
Last month the company reported a rise of 0.2% in revenue for the first half of the year but said net profit fell 35% year-on-year to 55.6 billion roubles.
A 7 year old girl on a birthday trip to Crater of Diamonds State Park in Arkansas found a big present a 2.95 carat diamond.
Arkansas State Parks said Aspen Brown of Paragould, Ark., was visiting the park with her family to celebrate her birthday when she spotted the diamond in the park’s north search area.
Officials said the 2.95 carat diamond is about the size of a green pea, with a golden-brown color.
The diamond is the second largest found by a park visitor this year, officials said. The largest was a 3.29 carat brown diamond found in March.
The Murfreesboro park was mined by commercial diamond hunters before becoming a state park in 1972.
