De Beers is moving its auctions headquarters from Singapore to Botswana in a move designed to streamline its operations and cut costs.
The UK-based miner sells around 10 per cent of its rough, by value, via online auctions to almost 1,000 registered buyers. The other 90 per cent is sold to sightholders.
In a statement the company said De Beers Group Auctions would pause it operations and sales events in the coming months, while the transition takes place.
Last year De Beers postponed its Cycle 5 and 6 auctions amid dwindling demand from Indian manufacturers and in January it introduced a new online “sealed bid” tender called The Offer for some of its rough diamonds.
Al Cook, De Beers Group CEO, said the move would drive cost efficiencies and support the needs of customers.
Last December Anglo American, parent company of De Beers said the diamond miner would have to cut $100m from its annual overheads in the face of ongoing weak demand.
De Beers moved its Sights from the UK to Gaborone, Botswana, in 2013.
Diamond output for De Beers slumped 23 per cent in the first quarter, as production was cut in response to a slow recovery in demand amid a pullback in luxury spending and the proliferation of lab-grown equivalents.
De Beers was the only unit of Anglo American to adjust its full-year production forecast on Tuesday, reducing its guided range to 26mn to 29mn carats of output, from 29mn to 32mn, and lifting expected average costs to $90 per carat, from $80.
Anglo American said the diamond market was suffering from a price rout caused by excess piles of inventory, something that De Beers has previously acknowledged is partly down to lab-grown diamonds cannibalising demand for mined stones.
“Ongoing uncertainty around economic growth prospects has led to a continued cautious purchasing approach” by its customers, Anglo American said. “The recovery in rough diamond demand is expected to be gradual through the rest of the year,” it added.
De Beers said a nascent recovery had begun in the first quarter, buoyed by improved demand for diamond jewellery around Christmas and new year in the US.
Diamond producers including De Beers’ arch-rival, Russia’s Alrosa, tried to curb the flow of gemstones into the market in the second half of last year. The Indian government even put on a voluntary import moratorium on rough stones in the final quarter to protect its polishers and cutters.
Despite those continued efforts into this year, demand, prices and the market recovery remains sluggish, Anglo said, requiring further action to be taken to reduce supply.
Anglo American chief executive Duncan Wanblad has been under pressure to improve performance since a production downgrade in December sent shares tumbling, although it has been aided by higher commodity prices, especially for copper.
Wanblad has said that “nothing is off the table” when it comes to asset sales or other options to restructure units, of which De Beers and the platinum group metals division are the most troubled.
“We are progressing through our asset review to optimise value by simplifying and improving the overall quality of the portfolio,” he said in a statement in the first-quarter production update on Tuesday.
Shares in Anglo American dropped 1.7 per cent in early trading in London and remain about a third lower than they were at the start of 2023.
Besides diamonds, the London-based company managed to maintain its guidance across its other commodities such as copper, iron ore and steelmaking coal.
Copper output jumped 11 per cent to 198,100 tonnes, helped by record throughput at its Quellaveco mine in Peru and higher grades at its Chilean mines Collahuasi and El Soldado.
South Africa, where Anglo American has iron ore, steelmaking coal and platinum mines, has become an increasing drag on production because of crippling problems in the logistics and power sector. Rail constraints resulted in a 2 per cent drop in output at Kumba Iron Ore.
Anglo American has announced the value of rough diamond sales (Global Sightholder Sales and Auctions) for De Beers’ second sales cycle of 2024, amounting to US$430 million.
The provisional rough diamond sales figure quoted for Cycle 2 represents the expected sales value for the period and remains subject to adjustment based on final completed sales.
Al Cook, CEO of De Beers, said: “I’m pleased to see a further increase in demand for De Beers rough diamonds during the second sales cycle of 2024. However, ongoing economic uncertainty in the US has led to retailers restocking conservatively after the 2023 holiday season. Consumer demand for diamond jewellery is growing in India but remains sluggish in China. Overall, we expect that the ongoing recovery in rough diamond demand will be gradual as we move through the year.”
Geologists from ETH Zurich and the University of Melbourne have established a link between diamond occurrence and the mineral olivine.
In a paper published in the journal Nature Communications, the scientists explain that their method will simplify the detection of diamond deposits. The process relies on the chemical composition of kimberlites, which occur only on very old continental blocks that have remained geologically unchanged for billions of years, predominantly in Canada, South America, central and southern Africa, Australia and Siberia.
According to the study’s lead author, Andrea Giuliani, olivine is a mineral that makes up around half of kimberlite rock and consists of varying proportions of magnesium and iron. The more iron olivine contains, the less magnesium it has and vice versa.
“In rock samples where the olivine was very rich in iron, there were no diamonds or only very few,” Giuliani, who has been studying the formation and occurrence of the gemstones since 2015, said in a media statement. “We started to collect more samples and data, and we always got the same result.”
His investigations ultimately confirmed that olivine’s iron-to-magnesium ratio is directly related to the diamond content of the kimberlite. Giuliani and his team took these findings back to De Beers, who had provided them with the kimberlite samples. The company was interested and provided the scientific study with financial support and asked the researchers not to publish the results for the time being.
A slow, repetitive process In 2019, Giuliani moved from Melbourne to ETH Zurich and, supported by the Swiss National Science Foundation, began to look for explanations for the connection between olivine’s magnesium and iron content and the presence of diamonds.
With his new colleagues, he examined how the process of metasomatism, which takes place in the earth’s interior, affects diamonds. In metasomatism, hot liquids and melts attack the rock. The minerals present in the rock react with the substances dissolved in the fluids to form other minerals.
The geologists analyzed kimberlite samples that contained olivines with a high iron content—and hence no diamonds. They discovered that olivine becomes richer in iron in the places where melt penetrates the lithospheric mantle and changes the composition of mantle rocks significantly. And it is precisely in this layer, at a depth of around 150 kilometres, that diamonds are present.
The infiltration of the melt that makes olivine richer in iron destroys diamonds. If, on the other hand, no or only a small amount of melt from underlying layers penetrates the lithospheric mantle and thus no metasomatism takes place, the olivine contains more magnesium—and the diamonds are preserved.
“Our study shows that diamonds remain intact only when kimberlites entrain mantle fragments on their way up that haven’t extensively interacted with previous melt,” Giuliani said.
A key point is that kimberlites don’t normally reach the earth’s surface in one go. Rather, they begin to rise as a liquid mass, pick up fragments of the mantle on the way, cool down and then get stuck. In the next wave, more melt swells up from the depths, entrains components of the cooled mantle, rises higher, cools, and gets stuck. This process can happen multiple times.
“It’s a real stop-and-go process of melting, ascent and solidification. And that has a destructive effect on diamonds,” Giuliani noted. If, on the other hand, conditions prevail that allow kimberlites to rise directly to the surface, then this is ideal for the preservation of the gemstones.
De Beers is already using olivine analysis Olivine analysis is as reliable as previous prospecting methods, which are mainly based on the minerals clinopyroxene and garnet. However, the new method is easier and faster: it takes only a few analyses to get an idea of whether a given kimberlite field has diamonds or not.
“The great thing about this new method is not only that it’s simpler, but also that it finally allows us to understand why the previous methods worked,” Giuliani said. “De Beers is already using this new method.”
De Beers has introduced a new online “sealed bid” tender for some of its rough diamonds.
The Offer, which went live last week, allows buyers to key in the price they’re prepared to pay for a lot, unseen by other bidders.
It is an additional sales channel rather than a replacement for the online auctions that have been taking place since 2008.
Online auctions have accounted for the 10 per cent of De Beers production that is not sold at Sights.
“We are constantly looking at new ways for customers to source natural diamond supply with a view to make the experience as simple and flexible as possible while keeping commerciality in mind,” said Rhyzard Bilimoria, account director in De Beers Group Diamond Trading.
“We believe that for certain product ranges and during certain industry conditions, the Offer represents the most effective channel to meet customer and industry needs.”
He said the Offer was quick, simple, confidential and allowed buyers to bid any amount.
“We recognise that in periods when trading conditions are evolving, different customers can perceive different value depending on their specific activities – it is therefore beneficial to implement a sales process where there is no visibility of other bidders’ activity, as this supports customers’ ability to make independent assessments of value that reflect their own underlying demand.”
De Beers cancelled its online auctions in the last two sales cycles of 2023 amid slow demand.
On Monday, De Beers’ customers turned up at the first day of the miner’s January sight to find rough prices were down by an average of 10% to 15%. The reductions were more drastic than many had predicted.
The drops ranged from slight adjustments for the more in-demand smalls, all the way to an estimated 20% to 25% cut for 2- to 4-carat, lower-clarity rough, sources said.
Sightholders usually celebrate a price decrease, since their margins can be thin at the best of times. But, immediately, the industry started asking the obvious question: Will this cause polished prices to fall?
The basic assumption is that cheaper raw materials mean cheaper end products. Yet the situation with diamonds is more complicated.
First, there are different ways of pricing polished. You can sell based on the current cost of replacing the goods — a method that would imply polished prices should fall, since De Beers rough is now cheaper. However, it’s also possible to price according to the input cost, with the vendor aiming for a certain profit based on how much the rough actually cost. This would, in theory, mean the latest drop in rough prices would not impact polished until around March, when the new, cheaper material enters the market as polished.
Still, most sightholders that spoke to Rapaport News this week don’t expect polished prices to suffer — though the people who buy their polished might disagree. The miner’s move, sightholders argue, was merely an adjustment to polished-price levels and to the price of rough at open tenders and auctions.
De Beers had priced its goods some 15% higher than the rest of the rough market, as it chose to sell less volume since August rather than discounting during the market slump. Its last significant price decrease before this was in July 2023. Since the start of that month, the RapNet Diamond Index (RAPI™) for 1-carat diamonds has fallen 12.5%.
Price drops at De Beers are not always in sync with the market. In recent years, the company has held off reducing prices until crises have eased, as it did in 2020 following the first round of Covid-19 lockdowns. De Beers sold just $216 million in rough at its last two trading sessions of 2023 as it followed this policy amid weak demand.
But the company needs revenue after incurring a loss in the second half of last year. It appears to have chosen the market improvement as an opportune time to stimulate sales.
“In the final quarter of 2023, we saw some stabilization in polished prices, including a number of areas of natural polished now starting to see some price increases,” a De Beers spokesperson said in a statement Wednesday. “Following this stabilization, we have realigned our rough-diamond trading activities, in terms of prices, volumes and supply flexibility, to reflect prevailing industry conditions.”
With the market in flux, De Beers also showed sightholders sample assortments of rough diamonds that indicated the types of goods and prices customers can expect for this year. Based on these so-called “to see” boxes, sightholders were able to apply for additional goods if their need for rough has increased since they submitted their supply applications in mid-December, the spokesperson explained.
However, market participants expect total sales at the sight of $300 million to $400 million — low for January, which is usually a time of post-holiday restocking. The recent season in the US was okay, but Chinese demand remains slow.
Whether sightholders maintain this cautious approach — and De Beers doesn’t sell too much — will be crucial. Excessive buying could lead to a repeat of last year’s oversupply, which ended with India’s two-month voluntary freeze on rough imports. During the recent crisis, De Beers continued selling — albeit at lower volumes — even when competitor Alrosa canceled sales.
At the January sight, De Beers also removed the extra concessions that had allowed sightholders to refuse goods in the final sights of last year without being penalized. The end of this flexibility increases the danger that goods will flood the market and that manufacturers will sell polished cheap to increase cash flow and raise money for rough.
The fact that De Beers diamonds remain relatively expensive could itself support polished prices, since sightholders have no room to offer further discounts.
“There’s no hooray if you look at those prices,” said one sightholder, noting that even the new rates will probably enable businesses to break even rather than turn a significant profit. “It’s just aligning with [reality]. It’s not like you’re going to make 10% [profit].”
Another sightholder agreed the reductions didn’t go far enough — but believed it would likely be up to the trade to drum up polished demand rather than expect further cuts to rough prices.
“If anybody thinks this is a price reduction — no, it’s a halfway correction, and not even achieving the final goal,” he asserted. “But I also believe they won’t do much [in terms of price cuts] after this. I think their expectation is: ‘Listen, we got you 60% of the way. The other 40%, you guys have to jump up now.’”
When the world’s most important diamond buyers arrived at De Beers’ offices in Botswana late last month, they were presented with a rare offer by their host: the option to buy nothing at all.
De Beers markets its rough diamonds in a series of tightly scripted sales, where handpicked buyers are normally expected to take all their contracted allocations at a price set by De Beers, or face potential penalties in the future. But with prices in free fall around the world, the one-time diamond monopoly has been forced to allow more and more flexibility, finally removing the restrictions altogether.
The concessions are the latest in a series of increasingly desperate moves across the industry to stem this year’s plunge in diamond prices, after slowing consumer demand left buyers stuck with swelling inventories. De Beers’s great rival, Russian miner Alrosa PJSC, already canceled all its sales for two months, while the market in India — the dominant cutting and trading center — had self imposed a halt on imports.
At the recent De Beers sale, its buyers, mostly from India and Antwerp, seized on the unusual flexibility, between them buying just $80 million of uncut gems. Normally De Beers would have expected to shift between $400 million and $500 million at such a sale. Outside of the early days of the pandemic — when sales were halted altogether — the company has not sold so few gems since it started making the results public in 2016.
The speed and severity of the collapse in diamond prices caught many by surprise.
The industry had been one of the great winners of the global pandemic, as stuck-at-home shoppers turned to diamond jewelery and other luxury purchases. But as economies opened up, demand quickly cooled, leaving many in the trade holding too much stock that they’d bought for too much money.
What looked like a cool down quickly turned into a plunge. The US economy, by far the industry’s most important market, wobbled under rising inflationary pressure, while key growth market China was hit by a real estate crisis that sapped consumer confidence. To make things worse, the insurgent lab-grown diamond industry started making major gains in a couple of key segments.
While there are many different diamond categories, broadly prices for wholesale polished diamonds have tumbled about 20% this year, firing a more dramatic fall in rough — or uncut — stones that have plunged as much as 35%, with the steepest declines happening though late summer and early autumn.
The industry’s response was to choke off supply in an almost unprecedented way, which finally seems to be working.
Prices at some smaller tender sales and auctions have risen between 5% and 10% in the past week as shortages of some stones start to emerge. With Indian factories set to reopen next month after prolonged Diwali closures, there is now renewed confidence that the worst has passed.
“The diamond industry has successfully taken action to stabilize things,” said Anish Aggarwal, a partner at specialist diamond advisory firm Gemdax. “That now creates a window to rebuild confidence.”
The plunge in diamond prices has coincided with weakness across the luxury space. LVMH Moet Hennessy Louis Vuitton SE, the luxury titan with 75 labels ranging from Christian Dior to Bulgari, has disappointed investors this year as China’s recovery underwhelmed and demand from US consumers cooled, with the stock shedding more than $100 billion in value since mid April. On Friday, Cartier owner Richemont reported a surprise decline in earnings as revenue from luxury watches unexpectedly fell and high-end consumers reined in spending.
Yet there are specific peculiarities to the diamond industry that make it more vulnerable to slowing consumer demand. De Beers sells its gems through 10 sales each year in which the buyers — known as sightholders — generally have to accept the price and the quantities offered.
When prices are rising, as they did for much of the past two years, these buyers are often incentivized to speculate, betting that paying for unprofitable stones now will pay off if prices continue to rise. Buyers are also rewarded for making big purchases by being given bigger allotments in the future, known in the industry as “buying for position.”
These mechanisms often lead to speculative bubbles, which pop when consumer demand slows and polished diamond inventories build up.
In response, Alrosa stopped selling diamonds altogether for two months, while the Indian diamond sector introduced a halt on imports that will run to mid December. De Beers has allowed its customers to refuse all purchases without it having any impact on the future allocations for its last two sales of the year.
While the two dominant diamond miners have a long history of curtailing supply or letting buyers refuse some goods when demand weakens, the speed and scale of the combined actions is extremely unusual outside of a major crisis such as the outbreak of the pandemic.
While prices have stopped falling — and in some areas rising again — much will depend on the crucial holiday season, which spans from Thanksgiving to Chinese New Year, and how the big miners who have accumulated large stocks of unsold gems feed them back into the market.
There also remains uncertainty in the industry about how much of the slowdown is being driven by macro-economic weakness, versus a more worrying shift in consumer choices. Lab-grown diamonds have made rapid progress in some key segments of the market, while there are lingering concerns in the industry about whether Gen Z consumers look at diamonds the same way as previous generations do.
“We expect there to be some cyclical recovery in the diamond markets,” said Christopher LaFemina, an analyst at Jefferies. “But we believe there are also structural issues here that could lead to weaker than expected demand for the longer term.”
De Beers has signed an agreement with South Africa’s National Union of Mineworkers (NUM) that will avoid a threatened strike at the Venetia deposit.
The deal will provide workers at the South African mine with a wage increase of 7% in 2023, De Beers said last week. The employees will also receive a 6% hike in each subsequent year until April 30, 2028.
Workers will also be able to participate in the Employee Share Ownership Plans (ESOPs), it explained.
De Beers reached the agreement with NUM with the aid of the Commission for Conciliation, Mediation and Arbitration (CCMA) following four months of failed talks during which the NUM set out 10 initial demands. Three of those — related to shifts and overtime — were tabled, while six others have been settled. The wage debate was the only outstanding issue, but the breakdown in discussions drove NUM to plan a strike at the deposit. The agreement affects 1,500 of the mine’s workers.
“We are pleased that we reached a favorable outcome following a very tough negotiation process against the backdrop of challenging market conditions that continue to have an adverse impact on our business and the overall diamond industry,” said Moses Madondo, managing director of De Beers Managed Operations, which oversees the company’s mines in South Africa and Canada. “The agreement provides a measure of certainty to our employees for the next five years as we focus on ramping up the underground mine at Venetia, which is set to extend the life of mine to at least 2046.”
Petra Diamonds’ rough prices decreased at its first tender of the fiscal year as the anticipated pickup in demand proved disappointing.
The August trading session brought in $79.3 million from the sale of 696,194 carats, with like-for-like prices — those for similar categories of diamonds — falling 4.3% compared with May, the miner reported Friday.
The slowdown was primarily due to flagging prices for rough between 2 and 10.8 carats, which dropped 14% on a like-for-like basis. Prices for diamonds under 2 carats rose 1% to 2%, Petra noted.
While the tender saw strong attendance, “demand was more muted than we had expected in exiting the summer holiday period,” explained Petra CEO Richard Duffy. “The expected seasonal improvement in demand was evident for higher-quality 10.8-carat-plus stones, with solid prices realized. [However,] this was offset by slower demand for 2- to 10-carat size ranges.”
The miner did not sell any exceptional stones during the tender, it reported, though it did garner $1.7 million for a 20.9-carat yellow diamond from its Cullinan deposit.
Overall sales value rose 88% from May’s $42.1 million but slid 23% from the equivalent tender a year earlier, which took place in September 2022. Sales volume was up 49% from May and 34% year on year, while the average price jumped to $114 per carat from the previous tender’s $90.
The August tender did not include any output from the Williamson mine; Petra plans to sell material from that site at its September sale. However, the latest round did feature all the rough Petra had chosen to defer in June, when it postponed its sixth tender due to the sluggish market.
The August sale also contained 75,880 carats of goods that Petra had withdrawn from the May tender due to low bids. Prices for those goods were largely unchanged from May’s offers, but Petra expects demand to rise in the coming months.
“As we enter a seasonally stronger period [that] includes Diwali, Thanksgiving, Christmas and the Chinese New Year, we remain optimistic that jewelry demand will improve and provide some support to prices over the balance of the calendar year,” Duffy said.

Julian Ogilvie Thompson, former chairman and CEO of De Beers as well as of its parent company, Anglo American, died on August 11 aged 89.
Ogilvie Thompson, a South African native, first joined Anglo American in 1956. He was promoted to personal assistant to then chairman Harry Oppenheimer a year later, De Beers told Rapaport News. In 1966, he joined the board of De Beers, and he became deputy chairman in 1982. Three years later, Ogilvie Thompson took over as executive chairman of De Beers, while Oppenheimer’s son, Nicky, filled his previous role.
In 1997, Ogilvie Thompson retired as chairman but remained deputy chairman until stepping down from the company in 2002. He was committed to supporting the development of young leaders from across Africa, forming an 18-year affiliation with the Mandela Rhodes Foundation, which offers scholarship and leadership programs to youth throughout the continent.
“Julian Ogilvie Thompson — often known in the business simply as JOT — was a hugely influential figure in the history not only of De Beers and Anglo American, but also in the broader South African landscape,” a De Beers spokesperson said. “As the former chairman and chief executive of both Anglo American and De Beers, and as a proud South African, he played a key role in shaping both companies and the nation.”
De Beers will allow sightholders to defer up to half of rough purchases to early next year amid sluggish consumer demand and high midstream stockpiles, market insiders told Rapaport News Wednesday.
The miner wrote to customers on Friday, informing them that they could avoid buying parts of their allocations of 1-carat goods and larger for the rest of 2023, the sources said on condition of anonymity. The allowance is 25% by value for some boxes and 50% for others, and applies to sights 8 to 10 — which will take place in September, October and December.
The rule does not apply to the August sight, which runs this week in Botswana, they added.
De Beers does not usually let sightholders defer more than one box per category of rough diamonds in each half year. In normal circumstances, failure to buy can affect access to goods in future intention-to-offer (ITO) periods — the yearlong session for which allocations are planned.
The new concession is unusual because it allows buyers to push off purchases to a new ITO. De Beers did not specify when the final deadline would be in early 2024, the sources said.
However, it told clients they must buy at least 65% of the non-deferred goods or the deferred stones will count as refusals, the sources explained.
The move comes amid persistent weak retail sales in the US and China. Manufacturers have been carrying large inventories of the less salable polished, especially in the 0.30- to 2.99-carat sizes that originate from rough above 0.75 carats.
“There is already a buildup of polished, and therefore there is enough…to fulfill the demand for the holiday,” said one of the sources. “[De Beers will] keep [the rough] for you rather than sightholders needing to buy it and store it themselves.”
Rough prices were stable at this week’s sight, while the buyback policy remains unchanged, the market participants noted. This allows clients to sell up to 10% or up to 30% of purchases back to De Beers, depending on the category.
“We continue to provide sightholders with elements of supply flexibility to support their business needs in response to evolving demand plans,” a De Beers spokesperson commented.
De Beers has sharply decreased its prices for select larger rough diamonds at this week’s sight, as the weak market has shown few signs of recovering.
The price cuts range from 5% to 15% in several categories for stones 0.75 carats and up, with an emphasis on 2-carat diamonds and larger, industry insiders told Rapaport News on Monday. Some of these goods already saw price reductions last month, they noted, while the 15% cuts are in a handful of sluggish categories that the miner left untouched in June.
De Beers has focused its adjustments on the lower-quality items for which demand has been especially slow, the sources said on condition of anonymity. Polished sales in SI to I2 clarities have slumped this year due to the overall weakness of US retail — the main market for this range — as well as competition from lab-grown diamonds.
The company also maintained its policy of allowing 30% buybacks for certain low-performing items, the industry sources said. Buybacks let sightholders sell a proportion of the rough they’ve purchased back to De Beers, allowing them to offload the stones that will generate the least profit. The limit is usually 10%.
De Beers declined to comment on the price changes.
The July sight — the sixth of the year — began Monday and runs through Friday in Gaborone, Botswana. It is the first sight since De Beers and the Botswana government announced a new 25-year mining license and a 10-year sales agreement that will see state-owned Okavango Diamond Company (ODC) gain access to 50% of the country’s rough over the course of 10 years.
The June session saw sales fall 32% year on year to $450 million after De Beers slashed prices of many categories above 1 carat. The negative trends that were present then have continued into July, with the seasonal US summer slowdown compounding the situation. Many manufacturers in India have lowered their polished production to around 50% capacity in response to low sales and tight margins. They have shifted to smaller, lower-value rough to keep factories running.
However, even a 15% price drop for rough is not enough to solve the problem, one executive at a sightholder company said Monday. “[Polished] prices have fallen more than that over the last couple of months. More importantly, there’s still no [foreseeable prospect] of sales. We are all still waiting for the US to wake up.”
De Beers’ sales value fell this month as global rough demand weakened and the miner reduced prices of its larger stones.
Proceeds dropped 32% year on year to $450 million at 2023’s fifth sales cycle from $657 million in the equivalent period a year earlier, De Beers reported Wednesday. Sales declined 6% compared with the $479 million that the fourth cycle brought in. The total included the June sight as well as auction sales.
“Following the JCK [Las Vegas] show, and with ongoing global macroeconomic challenges continuing to impact end-client sentiment, the diamond industry remains cautious heading into summer,” said De Beers CEO Al Cook. “Reflecting this, we saw demand for De Beers rough diamonds during the fifth sales cycle of the year slightly softer than in the fourth cycle.”
De Beers lowered prices at the sight by 5% to 10% mainly in 2-carat categories and larger, as well as for some 1- to 1.5-carat items, market insiders said. It also extended its buyback program, which allows sightholders to sell goods back to the miner following the purchase.
This reflected weakness in the rough that produces polished above 0.30 carats, and especially the stones that yield 1-carat finished diamonds. These sizes are especially weak in the US market amid economic uncertainty and a lull in engagements, dealers explained. Rough under 0.75 carats has seen a mild recovery as Indian manufacturers look to fill their factories with low-cost material.
Mountain Province Diamonds reports positive drilling results at several targets at the Gahcho Kué diamond mine 300 km east-northeast of Yellowknife, N.W.T. It has intersected 40 metres of kimberlite near the Tuzo resource and multiple intersections – as long as 287 metres of kimberlite – at the Hearne Deep and Hearne Northwest Extension targets.
The Gahcho Kué mine is a joint venture of Mountain Province (49%) and the operator De Beers Canada (51%).
The longest intersection, 287 metres, was drilled at the Hearne Northwest Extension. This target was identified late in 2021 when a 25-metre kimberlite exposure was discovered during routine mining operations in the Hearne pit. Drilling in 2022 pointed toward the presence of a significant, previously unknown kimberlite could exist. During the 2023 drill program, 10 of the 11 holes collared within and outside the Hearne pit intersected kimberlite.
“Combined with our earlier results, we now have 21 drillholes that define the extension below the final pit and to the northwest. We are actively engaged with our operating partner De Beers to look at ways to recover this deeper kimberlite by underground mining,” said Mountain Province president and CEO Mark Wall.
Following the success at the Hearne Northwest Extension, Mountain Province said drilling moved to the Tuzo kimberlite in the hope of finding a similar extension. A new kimberlite about 40 metres northeast of the modeled Tuzo resource was drilled. The intersection returned 40 metres of kimberlite.
Botswana may not renew a five-decade sales agreement with De Beers if the diamond producer doesn’t offer a larger share of rough diamonds to the state’s gem trading company, Okavango Diamond Company (ODC).
The move comes after the southern Africa nation acquired last month a 24% stake in Belgian diamond processing firm HB Antwerp for an undisclosed sum.
Analysts saw this deal as a way for Botswana to loosen the Anglo American-owned miner’s grip on its diamond sector, which is a major source of employment and tax revenue for the country.
De Beers and Botswana jointly own Debswana, which mines almost all of the roughs gems in the country — the world’s second-largest diamond producing nation after Russia.
The partnership has helped Botswana become one of Africa’s fastest growing economies, while supplying De Beers 75% of Debswana’s rough diamonds, which are then sorted and sold to sightholders around the world.
Debswana’s diamond sales hit a record $4.6 billion in 2022, compared to $3.4 billion in 2021.
President Mokgweetsi Masisi has threatened to walk away from the talks if Botswana does not get a larger share of Debswana’s output for marketing outside the De Beers system.
The government has not publicly stated what share it seeks, but it is believed to be as high as 50%, double its current allocation.
The two parties have been negotiating for several years to extend their 2011 mining rights and sales agreement, which is due to expire in June this year.
“Colonial” model Rafael Papismedov, co-founder of HB Antwerp, told the Financial Times that a revised deal would help Botswana break free from the current model of being “stuck in a box that says you can only dig and wash the diamonds.”
Papismedov added that De Beers’ operating model carries on “colonization” principles, acting as if Botswana was incapable of building midstream capabilities for polishing diamonds.
Masisi wants more locals employed in the diamond sector, which accounts for a fifth of the country’s gross domestic product.
The largest diamond producer by value has said it is confident that it can maintain its partnership with Botswana, but that some of the negotiations are complex and require more time.
De Beers has said that the arrangement must make economic and strategic sense for both parties, adding that it is committed to supporting Botswana’s aspirations to grow its diamond industry.
The stakes are high for both sides, as they seek to secure their future in a volatile and competitive industry that has been hit by the covid-19 pandemic, changing consumer preferences and ethical concerns.
A new deal between Botswana and De Beers could have significant implications for the global diamond supply chain and the balance of power in the sector.
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.
“The Eternal Pink,” a 10.57-carat internally flawless fancy vivid purplish-pink diamond
“The Eternal Pink,” a 10.57-carat internally flawless fancy vivid purplish-pink diamond, will be offered at Sotheby’s New York on June 8. Its estimate is $35 million, which if achieved, would make it one of the most valuable gems ever sold at auction.
Its per-carat estimate of more than $3.3 million is the largest such estimate ever placed on a diamond or gemstone, according to Sotheby’s.
Quig Bruning, head of Sotheby’s Jewelry, Americas, says it’s the most vivid pink diamond to ever to come to market. “This color is the most beautiful and concentrated shade of pink in diamonds that I have ever seen.”
The cushion-shaped diamond will first be on view in Hong Kong April 1 – 7 to coincide with the 50th anniversary of Sotheby’s presence in Asia. The gem will then travel to Dubai, Singapore, Shanghai, Taiwan and Geneva before being offered as the top lot at Sotheby’s New York Magnificent Jewels auction on June 8.
The 23.78-carat rough which yielded The Eternal Pink was mined by De Beers at the Damtshaa mine in Botswana. Diamond manufacturer, Diacore, took six months to cut and polish the gem into its current color, described as “bubblegum” by the auction house.
“This stunning diamond is the best of the best when it comes to exceptional pink diamonds and it is difficult to overstate its rarity and beauty,” said Wenhao Yu, chairman of Jewellery and Watches at Sotheby’s Asia.
Sotheby’s has had some experience with important pink diamonds. The auction house sold the record-breaking CTF Pink Star, a 59.60-carat oval mixed-cut Fancy Vivid Pink Internally Flawless diamond, sold for $71.2 million—a world auction record for a diamond and any gemstone or jewel—in Hong Kong in April 2017. More recently, Sotheby’s sold the Williamson Pink Star, an 11.15-carat fancy vivid pink internally flawless diamond, for $57.7 million in a single-lot auction at Sotheby’s Hong Kong on October 8, 2022, setting the world record price per carat for any diamond or gemstone at more than $5.1 million.
Colored diamonds continue to demand high prices at auction with exceptional pink and blue diamonds leading the way. It is because of their rarity, according to Sotheby’s. Of all the diamonds submitted to the Gemological Institute of America, fewer than 3% are classified as colored diamonds. Within these colored diamonds, pink is one of the rarest to occur naturally in diamonds. A diamond that is more than 10 carats, with strong color, internally flawless clarity, and classified as a “vivid pink,” the highest grade for a pink diamond is extremely rare.
De Beers’ sales fell at its February trading session as sightholders deferred demand to later in the year amid uncertain market conditions.
The second sales cycle of 2023 grossed $495 million, a drop of 24% from last year’s equivalent period, the company reported Wednesday. Sales were, however, 9% higher than January’s $454 million.
“We know that sightholders planned more of their purchases for later in 2023, given the economic uncertainty at the time they were taking their planning decisions at the end of 2022,” said Al Cook, De Beers’ new CEO. “It is also encouraging to see some positive trends in end-client demand for diamond jewelry at the start of the year.”
The total includes the company’s February sight as well as auctions. The company raised prices of its smallest diamonds for the contract sale, but mostly maintained rates for larger stones after January’s price decline, customers told Rapaport News.
De Beers’ rough revenues have fallen 28% year on year to $949 million for the first two sales cycles of 2023, according to Rapaport calculations based on the company’s sight reports.
De Beers has increased prices of small rough diamonds for the second consecutive sight as a combination of demand and supply factors continue to create a hot market for the category.
Prices for tiny stones rose by around 10% on average at this week’s trading session, with sharper advances in certain segments, customers and insiders estimated Monday. The changes were mainly for minus-7 sieve sizes, which weigh about 0.03 carats, across a range of qualities. De Beers was unavailable for comment.
The February sale runs this week from Monday to Friday in Gaborone, Botswana.
Rough under 0.75 carats became a sought-after asset in the second half of 2022 as melee demand from luxury brands strengthened and Indian manufacturers needed cheaper material to fill factories amid thin profit margins. In addition, Western sanctions on Russian diamonds created a mixture of real and perceived shortages in those sizes, for which Alrosa is the biggest supplier. The trade is watching for potential further restrictions as the one-year anniversary of Russia’s invasion of Ukraine approaches.
“Are people preempting what the [new] measures might be on Russia? [The strong market] might have to do with that,” a rough-market participant told Rapaport News on condition of anonymity.
Last year, De Beers made only modest increases in the prices of smalls, even when the segment saw robust demand, a sightholder explained on condition of anonymity. The miner raised prices at last month’s sight by approximately 10% — alongside decreases in the slower, larger goods.
The fresh hikes caught many dealers by surprise, as they were expecting De Beers to monitor the Chinese recovery before making further price adjustments.
