Star Diamond confirms Type IIa high value diamonds at Orion North, Taurus kimberlites

Star Diamond has completed a study into the abundance of Type IIa diamonds in parcels recovered from the Early Joli Fou geological units at the Orion North (K120, K147 and K148) and Taurus kimberlites (K118, K122 and K150).

The pipes are located within the Fort a la Corne diamond district of central Saskatchewan, including the Star–Orion South diamond project, on properties held in a joint venture with Rio Tinto Exploration Canada.

These diamond parcels were recovered by Star Diamond between 2006 and 2008 from 120-cm diameter drilling programs. The latest study confirms that unusually high proportions of Type IIa diamonds are present in both the Orion North and Taurus kimberlites.

Of particular note is the high proportion of Type IIa diamonds in the Orion North 147-148 EJF (52%), of which 66% of the 24 stones, 0.66 carats and above are Type IIa. The largest Type IIa diamond identified was a 6.88-carat stone from Orion North (K147-K148 EJF).

Senior technical advisor George Read said that the Type IIa diamonds at Orion North and Taurus are top white in colour, Type IIa diamonds are rare and account for less than 2% of all natural rough diamonds mined from kimberlites. Many high-value, top colour, large specials (greater than 10.8 carats) are Type IIa diamonds, which include all 10 of the largest known rough diamonds recovered worldwide.

The study also confirms and augments an earlier study of Type IIa diamonds being present in the Fort a la Corne kimberlites with Star (26.5%) and Orion South (12.5%).

A target for further exploration completed by Star Diamond in 2014 estimated that between 881 million and 1.04 billion tonnes of the major EJF units, containing between 46 and 79 million carats, occur within the Orion North and Taurus kimberlite clusters.

Orion North (K147, K148 and K220) alone is estimated to contain between 340 million and 410 million tonnes of EJF kimberlite with an estimated range of grade of 2.75 to 8.37 carats per hundred tonnes.

Sotheby’s Rakes In $57.5M for De Beers Blue

A record blue diamond co-owned by De Beers far outstripped its presale estimate in a stand-alone sale at Sotheby’s in Hong Kong, garnering HKD 450.9 million ($57.5 million), the auction house said Wednesday.

*The 15.10-carat De Beers Cullinan Blue diamond*

The step-cut, 15.10-carat, fancy-vivid-blue, internally flawless stone, called the De Beers Cullinan Blue, is the largest of its color to appear at auction. The stone, which sold to an unnamed buyer, had been expected to fetch up to $48 million.

Petra Diamonds discovered the 39.35-carat rough in April 2021 at its Cullinan mine in South Africa. In July, De Beers and Diacore bought the stone for $40.2 million, and Diacore manufactured the piece into the final polished.

To date, only five blue diamonds weighing more than 10 carats have come to auction, none of which has exceeded 15 carats, Sotheby’s explained. Similar blue diamonds have also fetched high prices, including the Blue Moon of Josephine, a cushion-shaped, 12.03-carat, fancy-vivid-blue, internally flawless diamond that sold for $48.5 million at Sotheby’s Geneva in 2015. Meanwhile, the Oppenheimer Blue, a step-cut, 14.62-carat, fancy-vivid-blue, VVS1-clarity stone, garnered $57.5 million at a Christie’s Geneva sale in 2016.

De Beers goes back into Angola after the country radically improves its investment legislation

De Beers is to start diamond exploration in Angola later this year after signing two mineral investment contracts with the Angolan government but the secretive group is giving little away on the details of the agreements.

De Beers announced today that the two licences covering prospects in the north-east of the country are for the “award and exercise of mineral rights covering all stages of diamond resource development from exploration to mining and span a period of 35 years.”

But the group does not specify its shareholding in the new developments which are joint ventures with Endiama – the Angolan government’s state-owned diamond company.

In a statement De Beers said only that “De Beers Group will hold a substantial majority in the new companies, with Endiama having the ability to incrementally increase its equity share over time in line with certain conditions outlined in the shareholder agreements, albeit with De Beers Group maintaining a substantial majority.”

By contrast, when Rio Tinto announced it was returning to Angola in October last year it specified that it would hold a 75% stake in the first phase of any mine developed with Endiama holding 25% but that the contract left open the possibility of Endiama increasing its holding to 49%.

De Beers’ return to Angola represents a breakthrough for the country following the regulatory and policy changes made by the government of President Joao Lourenco who replaced former president Jose Eduardo dos Santos in 2017.

Angola is arguably the most prospective country in the world in which to look for a major new diamond deposit but De Beers and most other diamond explorers left the country in the early 2000’s.

That was because of the repressive business conditions imposed by Dos Santos. These included a ban on any foreign company owning a majority interest in the diamond projects it was developing.

De Beers CEO Bruce Cleaver commented that, “Angola has worked hard in recent years to create a stable and attractive investment environment and we are pleased to be returning to active exploration in the country.

“Angola remains highly prospective and we look forward to being part of this next stage in the development of Angola’s diamond sector.”

Christie’s to Sell the Red Cross Diamond

One of the world’s largest yellow diamonds weighing 205.7 ct and known as the Red Cross Diamond is to be auctioned by Christie’s London.

The fancy intense yellow, cushion-shaped stone has a pavilion distinctively faceted in the shape of a Maltese cross.

The original rough gem was recovered by De Beers, in South Africa, in 1901 and was sold in 1918 in aid of the British Red Cross Society and the Order of St John.

It raised $13,000 equivalent to $780,000 in today’s money when it was sold at Christie’s London to the famous London firm S.J. Phillips.

It was sold again in November 1973, achieving CHF 1.8 million at Christie’s Geneva and returned to private ownership.

The diamond will again be offered for sale at Christie’s London on 11 May, with an undisclosed part of the sale revenue to be donated to the International Committee of the Red Cross.

We have asked Christie’s for the estimate, which is available “on request”.

De Beers returns diamond sights to Gaborone as travel opens up

De Beers is bringing its sales activities back to Botswana’s capital Gaborone, it said on Thursday, almost two years after the Covid-19 pandemic forced them to be held in cities including Antwerp and Dubai.

The Anglo American subsidiary had moved its pre-sale viewings – a marketing exercise to showcase its new batch of diamonds – from Botswana in May 2020 when travel restrictions to curb the pandemic prevented its international customers from flying to the Southern African country.

Customers from across the world fly ten times a year to participate in week-long diamond sales, known as sights, in Botswana, which accounts for 90% of the company’s total annual sales.

“From March, we are bringing back the sights to Gaborone and we look forward to meeting again as an industry after a long time,” De Beers Executive Vice-President Diamond Trading Paul Rowley told a press briefing.

“We will of course maintain some flexibility for some customers who will still not be able to come to Botswana.”

The return is expected to bring in valuable foreign exchange to Botswana, which had lost out additional earnings from travel, hospitality and ancillary services, even though sales income still came to the country.

The majority of diamond mining in the country is done by Debswana, a company jointly held by De Beers and the Botswana government, which sells 75% of the diamonds mined to De Beers. The remaining 25% of the diamonds is sold to state-owned Okavango Diamond Company.

Apart from the large business delegations who visit the country ten times a year, the pre-sale viewings are known to attract more than 100 high net worth diamond magnates who spend heavily in the country.

De Beers latest sale shows diamond demand remains strong

De Beers, the world’s top diamond producer by value, saw sales jump by 18% in the second cycle of 2022 compared to the same period last year, attesting to the industry’s consolidated recovery from the first pandemic-induced shutdowns.

The Anglo American unit sold $650 million of diamonds between February 21 to February 25, down $10 million from the first cycle of the year, but higher than the $550 million it sold in the second cycle of 2021.

De Beers sells its gems through 10 sales each year in Botswana’s capital, Gaborone, and the handpicked buyers known as sightholders generally must accept the price and the quantities offered.

Customers are given a black and yellow box containing plastic bags filled with stones, with the number of boxes and quality of diamonds depending on what the buyer and De Beers agreed to in an annual allocation.

The company said that owing to the restrictions on the movement of people and products in various jurisdictions around the globe, it has continued to implement a “more flexible approach” to selling roughs, which included extending the latest sight event beyond its normal week-long duration.

The miner, which has benefitted from a steady recovery in the diamond market, is said to have hiked prices by about 8% in January. It had already increased the price of its rough diamonds throughout much of 2021 as it sought to recover from the first year of the pandemic when the industry came to a near halt. Most of these hikes, however, were applied to stones bigger than 1 carat.

The strategy granted De Beers a steady recovery during 2021. Its diamond prices rose by 23% in “just over a year,” said Mark Cutifani, CEO of Anglo American in a December presentation.

Russia-Ukraine effect
De Beers may benefit from the sanctions imposed to Russian companies as Moscow-based Alrosa (MCX: ALRS), the world’s top diamond miner by output, is its main competitor.

Alrosa and its chief executive Sergei S. Ivanov were included in the first wave of restrictions announced by the US Department of the Treasury’s Office of Foreign Assets Control (OFAC), which targeted mainly banks and energy firms.

Data from the US Treasury shows Alrosa is responsible for 90% of Russia’s diamond production and 28% of global supply.

De Beers chief executive Bruce Cleaver said the company has been “shocked” and “saddened” by the war in Ukraine, so it will donate $1 million to aid organizations operating in the region and providing support to those affected by the ongoing conflict.

Experts believe that The Kremlin will soon be unable to pay its debts amid increasing international sanctions against Russia.

Credit ratings agency Fitch Ratings has downgraded its view of the country’s government debt, warning a default is “imminent” for the second time this month.

“The further ratcheting up of sanctions, and proposals that could limit trade in energy, increase the probability of a policy response by Russia that includes at least selective non-payment of its sovereign debt obligations,” the agency said.

Moscow has told investors that it will continue to service its sovereign debt but warned that international sanctions imposed on its energy industry could limit its ability and willingness to meet its obligations.

De Beers Raises Prices of Smaller Diamonds

*Sorting a parcel of rough diamonds Gaborone, Botswana.*

De Beers lifted prices of smaller rough at this week’s sight, its second consecutive increase, as the industry continued to express concerns about a perceived mismatch with polished.

Goods weighing less than 0.75 carats saw price hikes of around 5% at the February sale, while larger items were mostly stable, sightholders and industry insiders told Rapaport News this week.

The latest adjustments follow a strong US holiday season for retail and come amid robust demand in the polished sector while the industry restocks. Rough prices have rocketed in recent months, reflecting this appetite as well as supply shortages.

Prices at auctions and tenders have risen even more strongly than sight goods, with traders enjoying unprecedented premiums when reselling De Beers boxes on the secondary market.

However, manufacturers’ margins have suffered. This was a major point of discussion at the Dubai Diamond Conference, which took place Monday.

“There is still some buzz, but people are very cautious now because they’ve understood that prices have hit the ceiling and [De Beers] is facing resistance now with the new prices,” a sightholder said Tuesday on condition of anonymity. “There will be some stability and there has to be some mindfulness, because rough prices are outpacing polished prices so anyone who buys rough at those prices is not going to make a profit.”

The increases at the February sight followed sharper hikes in January, when rates jumped by up to 15% in the smallest categories and by 5% to 12% in larger sizes.

“What we try and do very hard at De Beers is price properly in accordance with demand,” De Beers CEO Bruce Cleaver told Rapaport News on the sidelines of the Dubai event. This is based on expectations of how the final polished will sell when it becomes available two or three months later, he explained. “Our crystal ball is no better than anyone else’s, but it’s based on a lot of data at the time that we make these pricing decisions.”

China Sales ‘Average’

Meanwhile, sales in the Far East during the recent Chinese New Year were steady, producing figures broadly in line with last year, dealers reported. This came despite headwinds in the latter months of 2021, including fresh Covid-19 outbreaks, a real-estate crisis, and power shortages.

The unfavorable comparison with last year’s season of post-lockdown recovery also affected the numbers, while fewer consumers took trips within China — usually a driver of seasonal demand, Cleaver pointed out.

“There’s no question that people are not traveling as much between the big Chinese cities and coming into the big Chinese cities to buy as they might have been because of [Covid-19],” he noted, cautioning that the information was preliminary. “In a sense, it could have been a bit better, but the early data I’ve seen is that it’s been an average to reasonable New Year.”

However, store openings in the mainland’s tier 3 and 4 cities are progressing well, he said.

“I don’t think there’s any reason to think that will slow down, and our clients tell us that’s continuing to happen,” the executive added.

The February sight, the second sale of the year, began on Monday and ends Friday.

Botswana’s Debswana diamond sales jump 73% in first nine months of 2021

Sales of rough diamonds by Debswana Diamond Company jumped 73% in the first nine months of 2021, statistics released by the Bank of Botswana showed on Tuesday, driven by the reopening of U.S. and China’s consumer markets.

Debswana, a joint venture between Anglo American business De Beers and the Botswana government, sells 75% of its output to De Beers, with the balance taken up by state-owned Okavango Diamond Company.

Debswana sales fell by 30% in 2020 as the covid-19 pandemic hit demand while global travel restrictions hurt trading.

Botswana closed its borders for eight months last year in an effort to curb the spread of the virus, effectively locking out foreign buyers from centres such as Mumbai, Antwerp and China, who traditionally travel to Gaborone 10 times a year to view and buy diamonds from De Beers.

Since mid-2020 De Beers has shifted some of its rough viewings to places closer to international diamond centres, such as Antwerp, to cater for customers unable to travel to Gaborone.

According to data published by the central bank, exports of diamonds from Debswana stood at $2.589 billion in the first nine months of the year compared with $1.498 billion in the same period last year.

Botswana makes about 30% of its revenue and 70% of its foreign exchange earnings from diamonds. While it has taken measures to diversify its dependence on a single commodity, diamond sales continue to be its main revenue earner.

De Beers’ sales softened by 4% in the current sales period, which ended last week, as Indian manufacturers closed factories ahead of the Diwali festival, though the company said diamond jewellery demand remained strong in the United States.

De Beers Looking at Greenland’s Marine Diamonds

De Beers has begun investigating Greenland’s potential as a source of high-value marine diamonds.

The miner commissioned a government agency to carry out a survey into diamond deposits, which are “known to be present” near the coast in the west of the Arctic island, according to an environmental assessment report by De Beers.

The Geological Survey of Denmark and Greenland (GEUS) — part of the Danish Ministry of Climate, Energy and Utilities — carried out the eight-day research in late September. GEUS set up and ran the survey, with De Beers requesting to extend it and participate in it, a spokesperson for the miner told Rapaport News Wednesday.

The purpose of the “small-scale, early-stage research” was to understand the region’s topography, he added, noting that it was unclear whether the location lent itself to concentrated sediments.

“De Beers Marine (DBM) would like to determine whether the offshore environment is conducive to the formation of secondary diamond deposits,” the environmental report said. “In order to do this, high-resolution geophysical data is required.”

Marine diamonds are generally of high quality, because only the best stones survive the impact of being washed around by water. De Beers currently mines marine diamonds off the coast of Namibia; the country’s 2020 rough production had a value of $465 per carat, one of the highest in the world, according to Kimberley Process data. The company is not carrying out similar surveys anywhere else, the spokesperson confirmed.

De Beers also operates land-based mining in Botswana, South Africa and Canada.

De Beers Prices Up 14% Since Start of Year

De Beers’ rough prices spiked in the first half of 2021 as supply shortages coincided with buoyant diamond demand at the trade and retail levels.

The miner’s price index rose 14% during the six months, reflecting “tightness in inventories across the diamond value chain, as well as positive consumer demand for polished diamonds,” parent company Anglo American said Tuesday.

De Beers implemented price increases at its January, February and June sights, with an emphasis on the larger categories of rough. This brought prices back to pre-pandemic levels: The index for the first half was flat versus the same period of 2020, the company reported.

Sales volume at De Beers rose to 7.3 million carats in the second quarter from just 300,000 carats a year earlier during the peak of the coronavirus crisis. The average sales price advanced 13% to $135 per carat as demand shifted to higher-value rough.

“Consumer demand for polished diamonds continued to recover, leading to strong demand for rough diamonds from midstream cutting and polishing centers, despite the impact on capacity from the severe Covid-19 wave in India during April and May,” the miner said.

Meanwhile, production more than doubled to 8.2 million carats for the quarter versus 3.5 million carats last year, reflecting planned increases to meet the stronger rough demand, as well as the sharp impact of lockdowns in southern Africa in 2020.

With half of 2021 now over, De Beers was able to give a more specific production outlook for the full year, predicting output of 32 million to 33 million carats — compared with a previous plan of 32 million to 34 million carats. The company has already reduced its guidance for the year twice because of operational issues at mines.

“Most of the impact on production for the year as a whole is a result of the challenges we experienced earlier in the year, particularly with excessive rainfall in southern Africa, the Covid-19-related shutdown in Canada, and power supply disruptions in Botswana,” a De Beers spokesperson commented. “We still expect production in the second half of the year to be significantly above the 15.4 million carats produced in the first half of the year, however, and this will take us to the narrower guided range.”

In the second quarter, output in Botswana more than tripled to 5.7 million carats from 1.8 million carats a year before. Production in Namibia slipped 6% to 338,000 carats, as one of the company’s mining vessels underwent planned maintenance and another remained demobilized.

Output in South Africa more than doubled to 1.3 million carats from 555,000 because the company processed higher-grade ore at the Venetia mine. Canada’s production climbed 14% to 899,000 carats, mainly reflecting the comparison with last year’s slowdown.
