India’s exports of polished diamonds fell by 23.8 per cent year-on-year in August, according to the latest figures from the GJEPC (Gem and Jewellery Export Promotion Council).
Total foreign sales were $1.04bn, compared to $1.36bn last August. Exports in July were $908m, down 22.7 per cent.
Polished diamond exports have fallen every month this year, down 20 per cent in January, 28 per cent in February, 27 per cent in March, 17 per cent in April, 15 per cent in May and 26 per cent in June. All figures are for US dollars.
Gross exports of all gems and jewelry fell by 18.8 per cent during August – a slower rate of decline than diamonds – to $2.01bn.
Rough imports for the April to August period were down 22.6 per cent to $4.98bn.
India’s exports of polished diamonds suffered a further drop in May, down by almost 15 per cent to $1.47bn.
But the year-on-year rate of decline shows some signs of slowing, according to new figures from the GJEPC (Gem and Jewellery Export Promotion Council).
It fell 20 per cent in January, 28 per cent in February, 27 per cent in March and 17 per cent in April.
Diamonds are faring significantly less well than India’s overall gems and jewelry sector, which saw revenue for April slip by 6 per cent to $2.48bn.
Manufacturers bought more diamonds year-on-year in April and May (up almost 2 per cent by volume) but the price slump means imports are down almost 10 per cent by value are down by almost 10 per cent to $2.39bn.
US Capitol building at sunset, Washington DC, USA.
US jewelers have warned Congress of the harm that new sanctions on Russian diamonds will cause for the entire retail sector.
The trade association Jewelers of America (JA) met with with a dozen Democratic and Republican lawmakers in both the House and Senate to voice concerns over the 1 September restrictions that will require all goods of 0.50-scts and above to enter G7 countries via Antwerp for verification.
They say a single import channel will “cause maximum damage to the global diamond and jewelry supply chain, while having minimal effect on Russia’s diamond revenues”.
JA is urging all its members to lobby Congress and explain that the way the restrictions are being implemented will hurt jewelry businesses.
“JA has been working tirelessly behind the scenes and this visit to Washington, D.C. was a critical step to ensure we minimize unnecessary disruptions to the U.S. diamond industry,” said JA president & CEO David J. Bonaparte.
He and fellow JA representatives also called for a “grandfathering” clause to cover goods imported before 1 March (when the 1.0-cts and above restriction was imposed) and for clearer guidance on whether the current size limit applied only to individual, loose diamonds or to the total weight of all diamonds in finished jewelry.
The US has sanctioned Zimbabwe President Emmerson Mnangagwa for corruption in connection with gold and diamond smuggling, as well as human-rights abuses.
The Treasury Department’s Office of Foreign Assets Control (OFAC) accused Mnangagwa of “providing a protective shield” to gold- and diamond-smuggling networks that operate in Zimbabwe, it said last week. He is also accused of directing Zimbabwean officials to “facilitate the sale of gold and diamonds in illicit markets” and taking “bribes in exchange for his services.”
The US has also restricted Mnangagwa for being a leader or official of entity, including any government entity, that has “engaged in, or whose members have engaged in, serious human-rights abuses,” OFAC explained.
“The Zimbabwe president is a foreign person who is a current or former government official, or a person acting for or on behalf of such an official, who is responsible for or complicit in, or has directly or indirectly engaged in, corruption, including the misappropriation of state assets, the expropriation of private assets for personal gain, corruption related to government contracts or the extraction of natural resources, or bribery,” OFAC stated.
OFAC issued the new sanctions after US President Joe Biden signed an executive order that terminated Zimbabwe’s national emergency and revoked sanctions on the entire country, so as not to target its citizens.
“The US remains deeply concerned about democratic backsliding, human-rights abuses, and government corruption in Zimbabwe,” said Wally Adeyemo, deputy secretary of the treasury. “The changes we are making today are intended to make clear what has always been true: Our sanctions are not intended to target the people of Zimbabwe. Today we are refocusing our sanctions on clear and specific targets.”
Botswana has designated BWP 890 million ($65 million) from its new fiscal 2024-2025 budget for the purchase of a 24% stake in Belgian manufacturer HB Antwerp.
The deal, which it first announced in March, calls for the African country to supply rough from state-owned Okavango Diamond Company (ODC) to HB Botswana for five years. The partnership would operate in a similar fashion to HB’s previous supply deal with Lucara Diamond Corp, enabling Botswana to retain a share of the polished profits.
Lucara terminated its rough-supply agreement with HB in September, citing a “material breach of financial commitments” by the Belgian manufacturer as the reason for the split. That decision came on the heels of HB’s departure from cofounder and managing partner Oded Mansori, whom it has since reinstated to his original role.
There was media speculation late last year that the Botswana government was pressuring Lucara to reconnect with HB, and that the split could affect Botswana’s interest in the manufacturer. Lucara owns the Karowe mine in Botswana. The miner has since announced that it planned to form new supply deals with other vendors.
Revenue from the Ekati deposit’s rough production soared during the fourth quarter as demand for its goods strengthened, according to owner Burgundy Diamond Mines.
Sales from the Canadian mine rose 37% year on year to $166 million for the three months that ended December 31, Burgundy reported last week. Sales volume jumped 41% to 1.8 million carats, from 1.3 million carats a year before, outweighing a 2% drop in the average price to $93 per carat.
Output increased 19% to 1.2 million carats for the October-to-December period. During the quarter, Burgundy held four auctions, including one for special stones. The miner sold all of its available inventory during those auctions, it noted.
“Each of our four auctions during the December quarter were oversubscribed due to significant customer demand,” said Burgundy CEO Kim Truter. “This has put us in a strong position with a healthy cash balance to fund the upcoming winter-road resupply and to commence the important work activities to extend the mine life at Ekati.”
Burgundy is currently retrieving ore from two sites at Ekati: an open-pit operation at Sable and an underground one at Misery. It is also working on extending Sable underground and is optimizing the Point Lake area.
Burgundy purchased Ekati from Arctic Canadian Diamond Company for $136 million in March.
A visitor from France who was in the United States to see a rocket launch in Florida found a 7.46-carat diamond at Crater of Diamonds State Park on Jan. 11, according to a news release from the park.
Julien Navas, of Paris, who was making his first visit to Crater of Diamonds on Jan. 11, found the diamond on the surface of the park’s 37.5-acre search area. It is the largest diamond registered at the park since 2020 and the eighth-largest in the park’s history.
Navas was visiting the U.S. to see the United Launch Alliance’s Vulcan Centaur Rocket launch in Cape Canaveral, Fla., the release said. After the launch, Navas traveled with a friend to see the sights in New Orleans. Along the way, he learned about Crater of Diamonds State Park, which “piqued his interest as he had previously panned for gold and searched for Ammonite fossils. So he knew he had to visit the park while he was in the U.S.”
A few days before his visit, the park had received over an inch of rain, making it a wet and muddy day. After purchasing his ticket and renting a basic diamond hunting kit from the park, “Navas headed into the search area and got to work.”
“I got to the park around nine o’clock and started to dig,” Navas said in the release. “That is backbreaking work so by the afternoon I was mainly looking on top of the ground for anything that stood out.”
According to Assistant Park Superintendent Waymon Cox, many of the park’s largest diamonds are found on the surface. “We periodically plow the search area to loosen the diamond-bearing soil and promote natural erosion,” he said in the release. “As rain falls on the field, it washes away the dirt and uncovers heavy rocks, minerals, and diamonds near the surface.”
After searching for several hours, Navas carried his finds to the park’s Diamond Discovery Center, where he learned that he had discovered a brown diamond weighing 7.46 carats. When he learned that he had found a diamond, the release said, Navas was stunned and said, “I am so happy! All I can think about is telling my fiancée what I found.”
The diamond has a deep chocolate brown color and is rounded like a marble. It is about the size of a candy gumdrop.
“It is always so exciting to see first-time visitors find diamonds, especially large diamonds like this one,” Park Interpreter Sarah Reap said in the release.
Navas called Crater of Diamonds State Park “a magical place, where the dream of finding a diamond can come true! It was a real great adventure.”
Navas said he plans to return to the park with his daughter when she is older.
“Many visitors choose to name the diamonds they find at Crater of Diamonds State Park. Navas decided to name his find the Carine Diamond, after his fiancee. He said he hopes to have the stone cut into two diamonds, one for his fiancee and one for his daughter,” the release said.
The Carine Diamond is the largest diamond registered at the park since 2020, when Kevin Kinard found the 9.07-carat Kinard Friendship Diamond over Labor Day weekend. It is the eighth-largest diamond registered since the Crater of Diamonds became a state park in 1972, according to the release.
Eleven diamonds have been registered at Crater of Diamonds State Park in 2024 so far. An average of one to two diamonds are found by park visitors each day.
“In total, over 75,000 diamonds have been unearthed at Crater of Diamonds State Park since the first diamonds were discovered by John Huddleston, a farmer who owned the land long before it became an Arkansas State Park in 1972. The largest diamond ever discovered in the United States was unearthed in 1924 during an early mining operation on the land that later became the state park,” the release said.

Africa-focused miners Gem Diamonds and Lucara Diamond have recovered big, high-quality Type IIa diamonds at their respective operations.
Gem Diamonds said on Thursday it had unearthed a 295-carat rough stone at its Letšeng mine in Lesotho, adding to a long list of diamonds over 100 carats found at the operation over the past two years.
The prolific mine is one of the world’s ten largest diamond operations by revenue. At 3,100 metres (10,000 feet) above sea level, Letšeng is also one of the world’s most elevated diamond mines.
Canada’s Lucara recovered a 166-carat rough in the Coarse X-Ray Transmission unit at its Karowe diamond mine in Botswana. The company said the precious stone was sourced from direct milling of ore from the South lobe of the mine.

Lucara’s latest find is the 328th diamond over 100 carats found at Karowe since it began operations in 2012. Chief executive William Lamb said the recovery further supported the economic rationale for investing in the underground expansion project to extend the mine’s life to at least 2040.
The recoveries bring some positive news into a market affected by ongoing weak conditions, with prices for wholesale polished diamonds dropping 20% last year, which also dragged down rough diamond prices.
Rio Tinto is reshuffling its interests in two Canadian projects as the global miner seeks to focus on assets considered key for the world’s transition to a green economy, such as copper and lithium.
The company has decided to sell its 75% interest in the Fort à la Corne diamond project in central Saskatchewan to joint venture partner Star Diamond Corp. in exchange for shares in the junior.
As a result, Rio Tinto Exploration Canada will own a 19.9% stake in the exploration and development company.
Rio Tinto’s head of exploration Dave Andrews said the company was now “firmly focused” on identifying opportunities in metals and minerals that support the energy transition.
“We are grateful to Rio Tinto for the significant monetary investment and expertise it has contributed to the project over the past more than five years, which has meaningfully advanced what Star Diamond believes is one of the most promising diamond projects in the world,” president and CEO Ewan Mason said in a statement.
Rio Tinto’s move follows years of tension between the partners over the terms of their development agreement. The situation saw both companies face off in court and, at one point Star Diamond considered cutting RTEC out of the project.
The partners reached an agreement on the subject in December 2021, after which RTEC put the project on hold until it could determine whether it wanted to continue or exit the venture. The camp was demobilized, and the project put on care and maintenance in the first quarter of 2023.
Copper and lithium Rio Tinto has also moved to increase its stake in Canada’s Western Copper and Gold Corporation (TSX: WRN), which is advancing the Casino project in the Yukon Territory.
Under the deal, RTEC is acquiring 3,468,208 common shares at a price of C$1.73 per share, or about C$6 million ($4.4m) total. This increases Rio Tinto’s ownership to 9.7% of Western’s outstanding common shares.
Vancouver-based Western Copper and Gold, which remains the sole owner of the Casino project, said it would use the proceeds of this fresh investment to fund specific areas of study with the aim of progressing through permitting to a development phase of the proposed mine.
“We are pleased that Rio Tinto has elected to continue to invest and work with Western to advance the Casino project, with a focus on furthering infrastructure development and streamlining the regulatory process,” CEO Paul West-Sells said in the statement.
Rio Tinto chief executive officer Jakob Stausholm recently said in an interview that the company continued to look for ways to increase exposure to key minerals and metals, particularly copper and lithium.

Gem Diamonds has recovered a 117.47-carat rough from its Letšeng mine in Lesotho, its fourth over 100 carats so far this year.
The miner discovered the gem-quality, type IIa diamond on October 29, it said Tuesday. The find follows that of a 101.96-carat high-quality rough on September 28, and a 163.91-carat yellow diamond on June 22. The company also unearthed a 122-carat stone on March 5.
Letšeng has been known for producing high-quality rough diamonds topping the 100-carat mark, but recently that supply has been dwindling. However, the newest recovery brings this year’s total to a tie with last year, when the miner also retrieved four diamonds in that category. That compares with six in 2021 and 16 in 2020.
The declining number of special-size stones has put a dent in the company’s revenue, with sales falling 28% year on year to $71.8 million in the first six months of 2023. The miner incurred a loss of $1 million, versus a profit of $3.8 million during the same period in 2022.
Stornoway Diamonds has suspended operations at its Renard mine in Canada amid the prolonged slowdown in demand for rough.
“The growing uncertainty of the diamond price in the short and medium term, coupled with the significant and sudden drop in the price of the resource on the world market, has had a major impact on the company’s long-term financial situation,” Stornoway said Friday. “This was in part due to the halt in the import of rough diamonds to India, and [in part to] the global geopolitical climate.”
The company will put Renard on care and maintenance to “preserve the assets and facilitate a rapid return to normal operations,” it explained. It will keep 75 of its 500 workers on staff to perform necessary tasks.
Stornoway will also seek creditor protection under the Canadian Companies’ Creditors Arrangement Act (CCAA), which allows financially troubled corporations owing more than $5 million to restructure their businesses and avoid bankruptcy. As part of this effort, the miner is “implementing a process for soliciting investment and sale proposals,” it added.
The Indian diamond-manufacturing sector announced in September that it was implementing a two-month moratorium on rough imports, from October 15 to December 15, to help reduce some of the oversupply that has built up in the midstream due to weak industry demand.
This is not the first time Stornoway has sought creditor protection under CCAA. In 2019, one of its creditors, Osisko Gold Royalties, acquired and revived the company during a restructuring process. Under the new ownership, the miner restarted operations in 2020 following a six-month halt due to Covid-19.
Gem Diamonds has unearthed a 101.96-carat rough from its Letšeng mine in Lesotho, its second stone over 100 carats so far this year.
The miner discovered the gem-quality, type IIa diamond on September 28, it said Wednesday. The find follows that of a 122-carat stone on March 5.
While Letšeng had previously been known for producing high-quality rough diamonds topping the 100-carat mark, that supply has been declining. Last year, the miner retrieved only four diamonds of that magnitude, versus six in 2021 and 16 in 2020.
The lack of special-size stones has hurt the company’s revenue, with sales falling 28% year on year to $71.8 million in the first six months of 2023. The miner incurred a loss of $1 million, compared to a profit of $3.8 million during the same period in 2022.
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.
Alrosa’s diamond sales have been unaffected by sanctions, according to the company’s first published set of financial results since Russia invaded Ukraine in February 2022.
First-half sales for 2023 were RUB 188.2 billion ($1.9 bn), up 0.2% from RUB 187.8bn ($1.9 bn), for H1 of 2022, and up 3.5 per cent on H1 of 2021. Net profit for H1 2023 was down 35 per cent year-on-year to RUB 55.57bn ($562.5m).
More detailed breakdowns of diamond sales are marked as being restricted by decree of the Government of the Russian Federation.
The US has imposed banking restrictions and sanctioned direct imports of Russian diamonds. But Russian stones polished elsewhere are not sanctioned.
The G7 countries were expected to impose restrictions when they met in May, but instead announced plans to consider a traceability solution.
India and Dubai have not imposed restrictions on Russian diamonds.
In its interim financial statement, Alrosa, the state-controlled diamond miner, says: “Ongoing geopolitical tensions in the region have escalated significantly as the situation regarding Ukraine continues to evolve, which remains highly volatile.
“The sanctions against Russia, in turn, have caused economically unjustified costs in a number of foreign economies, disrupted the efficiency of supply chains and trade flows.”
Sarine Technologies saw a drop in revenue and a sharp slide in earnings for the first half of 2023 as demand for the company’s manufacturing equipment slowed.
Sales declined 24% year on year to $23.7 million in the six months that ended June 30, the Israel-based producer of technology for the diamond industry reported Sunday. Profit plummeted 85% to $953,000, as lower sales and a weaker product mix reduced margins.
High inflation and rising interest rates dented consumer demand, as did a sluggish post-pandemic recovery in China, Sarine explained.
“With a decline in the sale of polished diamonds, and the subsequent reduction of rough diamonds in the pipeline, the midstream effected less manufacturing activities,” the company said. “Appropriately, our traditional business of selling capital equipment and, to a much lesser extent our inclusion scanning services, were affected.”
Recurring revenues — from fees clients pay when they use Sarine systems, such as its Galaxy rough scanners — decreased around 9%. Outright sales of capital equipment — customers’ one-off purchases of machines — fell 40%. “Teething” problems with Sarine’s Meteorite Plus, a scanning machine for small rough stones that launched late last year, also impacted the top line. The company has rectified these issues, it said.
Revenues from services to the retail and wholesale segments, which Sarine calls trade revenues, offset the declines with a 12% rise. This mainly resulted from the acquisition of New York-based Gem Certification & Assurance Lab (GCAL) earlier this year, Sarine said.
Overall prospects for the coming months remain gloomy, the company added.
“As interest rates and inflation are likely to stay elevated and the possibility of a recession in the US is still realistic, overall industry conditions are likely to remain challenging for the rest of [2023],” it said. “Our traditional businesses of selling capital equipment and, to a much lesser extent, our Galaxy scanning services, will remain affected under subdued market conditions.”
New findings hold the potential to spark future diamond discoveries.
An international team of scientists, led by the University of Southampton, has found that the breakup of tectonic plates is the main driving force behind the generation and eruption of diamond-rich magmas from deep inside the Earth.
This insight could significantly influence the trajectory of the diamond exploration industry, guiding efforts to locations where diamonds are most probable.
Diamonds, which form under great pressures at depth, are hundreds of millions, or even billions, of years old. They are typically found in a type of volcanic rock known as kimberlite. Kimberlites are found in the oldest, thickest, strongest parts of continents – most notably in South Africa, home to the diamond rush of the late 19th century. But how and why they got to Earth’s surface has, until now, remained a mystery.
The new research examined the effects of global tectonic forces on these volcanic eruptions spanning the last billion years. The findings have been published in the journal Nature.
Southampton researchers collaborated with colleagues from the University of Birmingham, the University of Potsdam, the GFZ German Research Centre for Geosciences, Portland State University, Macquarie University, the University of Leeds, the University of Florence, and Queen’s University, Ontario.
Tom Gernon, Professor of Earth Science and Principal Research Fellow at the University of Southampton, and lead author of the study, said: “The pattern of diamond eruptions is cyclical, mimicking the rhythm of the supercontinents, which assemble and break up in a repeated pattern over time. But previously we didn’t know what process causes diamonds to suddenly erupt, having spent millions – or billions – of years stashed away 150 kilometers beneath the Earth’s surface.”
To address this question, the team used statistical analysis, including machine learning, to forensically examine the link between continental breakup and kimberlite volcanism. The results showed the eruptions of most kimberlite volcanoes occurred 20 to 30 million years after the tectonic breakup of Earth’s continents.
Dr. Thea Hincks, Senior Research Fellow at the University of Southampton, said: “Using geospatial analysis, we found that kimberlite eruptions tend to gradually migrate from the continental edges to the interiors over time at rates that are consistent across the continents.”
Geological processes
This discovery prompted the scientists to explore what geological process could drive this pattern. They found that the Earth’s mantle – the convecting layer between the crust and core – is disrupted by rifting (or stretching) of the crust, even thousands of kilometers away.
Dr Stephen Jones, Associate Professor in Earth Systems at the University of Birmingham, and study co-author said: “We found that a domino effect can explain how continental breakup leads to the formation of kimberlite magma. During rifting, a small patch of the continental root is disrupted and sinks into the mantle below, triggering a chain of similar flow patterns beneath the nearby continent.”
Dr. Sascha Brune, Head of the Geodynamic Modelling Section at GFZ Potsdam, and a co-author on the study, ran simulations to investigate how this process unfolds. He said: “While sweeping along the continental root, these disruptive flows remove a substantial amount of rock, tens of kilometers thick, from the base of the continental plate.”
The typical migration rates estimated in models matched what the scientists observed from kimberlite records.
“Remarkably, this process brings together the necessary ingredients in the right amounts to trigger just enough melting to generate kimberlites,” added Dr Gernon.
The team’s research could be used to identify the possible locations and timings of past volcanic eruptions tied to this process, offering valuable insights that could enable the discovery of diamond deposits in the future.
Professor Gernon, who was recently awarded a major philanthropic grant from the WoodNext Foundation to study the factors contributing to global cooling over time, said the study also sheds light on how processes deep within the Earth control those at the surface: “Breakup not only reorganizes the mantle, but may also profoundly impact Earth’s surface environment and climate, so diamonds might be just a part of the story.”

Istanbul Police, Tuesday, seized unprocessed raw diamonds with a market value of TL 20 million ($1 million), estimated to be 61.38 carats, during an operation in the Grand Bazaar – one of the historical trade centers of Istanbul, local Turkish media reports.
According to the report, the Istanbul Police Department and the Department of Combating Financial Crimes received information about the smuggling of diamonds in the historic Grand Bazaar, Istanbul.
They detained four foreign national suspects, the report added.
It was determined that the seized diamonds were brought to Turkey illegally, via Africa.
De Beers, the largest diamond producer by value, has unveiled a unique piece it named the “Beating Heart”, a 0.33-carat rough specimen that consists of a diamond within another diamond.
The unusual discovery – a D-colour, type IaAB diamond – has an internal cavity enclosing a smaller loose diamond, which is trapped, yet free to move around within the space.
De Beers said the gemstone was discovered at one of its mines in either Africa or Canada, but the exact origins can’t be pinpointed.
It arrived at the De Beers Institute of Diamonds facility in Maidenhead, England, in November last year, where it was verified to be a natural occurring stone.
Initial conclusions from the Institute’s experts suggest that an intermediate layer of poor-quality diamond etched away during its travel to the surface of the Earth, leaving only the better-quality material: the outer diamond and the core.
“The ‘Beating Heart’ is a remarkable example of what can happen on the natural diamond journey from formation to discovery,” Jamie Clark, Head of Global Operations at De Beers Institute of Diamonds, said in the statement.
Now registered on De Beers’ Tracr blockchain platform, which certifies a diamond’s provenance and production journey, the “Beating Heart” will be kept in its rough form for research and educational purposes.
Competitor Alrosa found a similar diamond in 2019, which was named “Matryoshka” after the famous Russian nesting dolls. The 0.62 carat gem, estimated to be over 800 million years old, resulted from one diamond growing inside another, according to Alrosa’s scientists.
