Australia’s Lucapa Diamond has unearthed a 235 carat type IIa diamond from its prolific Lulo mine, the second largest recovered at the Angola operation since it opened in 2015.
The find comes barely a week after the recovery of a 208 carat diamond at the same mine, which is the third-largest ever recovered from Lulo.
The new diamond was dug up from Mining Block 550, immediately south of Mining Block 19, which Lucapa said is the area that has yielded eight precious rocks over 100 carats to date.
Not surprisingly, the mine is considered the world’s highest dollar per carat alluvial diamonds operation, in which Lucapa has a 40% interest. The rest is held by Angola’s national diamond company (Endiama) and Rosas & Petalas, a private entity.
The partners have now recovered 40 diamonds weighing more than 100 carats and four over 200 carats at Lulo. In 2016, only a year after beginning commercial production, Lulo produced the largest ever diamond recovered in Angola a 404 carat white stone later named the “4th February Stone”.
“Lulo continues to demonstrate it is a prolific producer of large diamonds. To unearth three +100 carat diamonds with two being over 200 carats in such a short space of time from different areas of the concession, makes us more determined to find the primary source, by dedicating even more resources to the exploration program,” Lucapa managing director, Nick Selby, said in the statement.
Angola is the world’s fifth diamond producer by value and sixth by volume. Its industry, which began a century ago under Portuguese colonial rule, is successfully lessening government regulations and restrictions in favour of a greater participation by private entities.
Growth at the retail division of Warren Buffett’s Berkshire Hathaway slowed in the third quarter amid a drop in customer traffic.
The unit which includes jewelry chains Borsheims, Helzberg Diamonds and Ben Bridge Jeweler saw sales increase 1% year on year to $4.85 billion, the company reported Saturday. That represented a gentler rise than the 5% gain the company noted the previous year. Pretax earnings for retail rose 4.5% to $414 million.
The decline in the number of shoppers was primarily at the conglomerate’s home furnishings businesses. However, strong sales of cars, which make up the largest portion of Berkshire’s retail division, offset that decrease.
Revenues from the manufacturing of consumer products, including jewelry maker Richline Group, grew 2% to $3.77 billion, while pretax earnings surged 78% to $483 million.
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.”

Lucapa Diamond has recovered a 208 carat diamond at its prolific Lulo mine in Angola, the third largest ever found at the operation.
The company said the high quality, type IIa diamond was unearthed at the lizeria, or terrace area, of its Mining Block 31 portion of Lulo, known for delivering high value stones.
The diamond is also the second 100 carat plus stone Lucapa retrieved in October, following the recovery of a 123 carat, type IIa rough at the start of the month.
The mine, which hosts the world’s highest dollar per carat alluvial diamonds, began commercial production in January 2015. Only a year later, it delivered the largest ever diamond recovered in Angola a 404 carat white stone later named the “4th February Stone”.
Lucapa finds Lulo mine’s third largest diamond It is the second 100 carat plus diamond found at Lulo in October. The operation has delivered 39 diamonds weighing more than 100 carats each to date.
Lucapa has a 40% stake in the Lulo mine. The rest is held by Angola’s national diamond company (Endiama) and Rosas & Petalas, a private entity.
Angola is the world’s fifth diamond producer by value and sixth by volume. Its industry, which began a century ago under Portuguese colonial rule, is successfully being liberalized.
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.
Internal diamond crystals are small diamond inclusions or crystals that are enclosed within a larger diamond. These internal diamond crystals can take various forms, and their presence is a common characteristic in many diamonds.
Here are a few key points about internal diamond crystals:
Nature of Inclusions: Internal diamond crystals are typically tiny diamond fragments or crystals that were present in the diamond-forming environment when the host diamond was growing. These internal crystals can vary in size and shape.
Inclusion Types: Internal diamond crystals are a type of inclusion. Inclusions in diamonds can also include non-diamond materials like minerals, other types of crystals, or even gas bubbles.
Impact on Clarity: The presence of internal diamond crystals, like other inclusions, can affect a diamond’s clarity. The size, type, and visibility of these inclusions play a role in determining a diamond’s clarity grade, which is one of the factors used to evaluate a diamond’s overall quality and value.
Grading and Certification: When a diamond is sent to a Internationally recognised gemological laboratory, such as the DCLA, GIA , HRD, AGS or IGI for grading and certification, the presence of internal diamond crystals, as well as other inclusions, is documented in the diamonds grading report.
Visibility: The visibility of internal diamond crystals can vary widely. In some cases, these internal crystals may be barely visible even under magnification, while in other cases, they may be more apparent.
It’s important to note that the presence of internal diamond crystals does not necessarily make a diamond less valuable. The overall beauty and value of a diamond depend on various factors, including the “Four Cs” (carat weight, cut, color, and clarity), as well as the specific characteristics of the inclusions and their impact on the diamond’s appearance.
Botswana’s state-owned Okavango Diamond Company (ODC) has temporarily halted its rough stone sales as part of an industry-wide drive to reduce the glut of inventory caused by lower global demand for jewelry, its managing director Mmetla Masire said on Tuesday.
ODC, which reported a record $1.1 billion in revenue in 2022, holds 10 auctions a year to sell its 25% allocation of production from Debswana Diamond Company, a joint venture between Anglo American’s (AAL.L) De Beers and Botswana, in terms of the partners’ gem sales agreement.
Debswana produced about 24 million carats last year, with ODC getting an allocation of about 6 million carats.
The company has cancelled its November auction and a decision on the December sale is still to be made as the industry battles slowing demand for cut and polished diamonds in the U.S and China, Masire said.
“For the first time, we have had to build up inventory as we do not want to just irresponsibly release goods into a market which is already oversupplied,” Masire said in an interview. “For now, we have stopped the auctions, we will decide on the December auction.”
Last month, trade bodies in India, which cuts and polishes 90% of the world’s rough diamonds, urged members to halt rough diamond imports for two months to manage supplies and aid prices due to weak demand.
In August, De Beers said it would allow its customers to defer some of their purchases for the rest of the year.
As part of a new agreement between De Beers and Botswana, ODC’s allocation is set to rise to 7 million carats. Masire said the company was working on introducing contract sales, a model that De Beers uses to sell 90 % of its supply, among other new sales channels.
“We are still to decide on what percentage of our allocation will be sold through contract sales to complement our auctions,” Masire said. “We are likely to have two-year sales contracts and we are looking at going into partnership with only a limited number of buyers so that we can better serve them.”
The diamond sorting center in Mirny, Sakha Republic, Russia, November 14, 2013.
De Beers has put its weight behind the World Diamond Council (WDC) plan for sidelining Russian goods amid continued controversy over the competing proposals.
“In pursuit of a collaborative, coherent and collective solution that supports the aims of the G7, we have joined with 22 diamond-industry organizations through the World Diamond Council to progress the ‘G7 Diamond Protocol’ proposal,” De Beers CEO Al Cook wrote in an open letter to Group of Seven (G7) leaders on Thursday. “
The protocol — one of a few plans for keeping Russian diamonds out of G7 nations — calls for importers to declare on invoices that stones do not originate from mining companies operating in Russia. The companies making the claims will undergo audits.
While the WDC-led proposal has received wide industry support, it has also drawn criticism for creating a burden for small-scale industry members — including by Rapaport Group Chairman Martin Rapaport.
One other plan, from the Belgian government and supported by the Antwerp World Diamond Centre (AWDC), proposes using technology to confirm the source of goods, with the European city as a suggested center point for the trade of stones with known provenance.
Two further proposals — from India and a French jewelry group — were also on the table at a G7 meeting on Thursday, Reuters reported.
In another letter earlier this month, the African Diamond Producers Association (ADPA) attacked the process for not consulting people on the continent and claimed some of the plans would harm its members and artisanal miners. It highlighted the “G7 Certificate Scheme” — an apparent reference to the Belgian plan — as well as the WDC protocol.
“The proposed changes will bring supply-chain disruption, added burden, and costs to the ADPA mining nations,” the ADPA wrote in the October 13 letter to the Zimbabwe Minister of Mines and Mining Development, Soda Zhemu, who is chairing the Kimberley Process (KP) this year.
The plans will set a precedent for segregating diamonds by origin and damage producing countries’ ability to cut and polish their rough, the group argued.
In the case of the Belgian proposal, “additional costs will be incurred when a parcel of rough diamonds needs to be first shipped to Antwerp to then be reshipped to the country of origin to be polished,” said the Angola-based ADPA, which represents 19 countries that together account for 60% of global rough production.
Efforts to sift Russian diamonds out of G7 markets have taken on momentum since the bloc — which comprises Canada, France, Germany, Italy, Japan, the UK, the US, and the European Union — pledged to “work closely together to restrict trade” in those goods in May.
Where Are All the Russian Diamonds?
However, while there has been agreement about the need to stop Russia obtaining diamond revenues to fund its war in Ukraine, the process of implementing this has proven complex.
“Throughout our discussions, two things have been clear: why we should do this is easy, but how we should do it is hard,” said Cook.
The executive called for G7 leaders to obtain input from the industry and not exclude relevant groups, including artisanal miners.
“We look forward to further engagement with the G7 around the World Diamond Council proposal and urge those that have submitted proposals to work together to create an effective and practical solution,” Cook continued.
The industry had expected any measures to go into effect in January 2024. However, that schedule is now looking unlikely, JCK reported Friday, citing sources involved in the plans.
“We fully agree with Al [Cook]’s view that the results of our efforts to meet the G7 objectives should be collaborative, coherent and collective,” said WDC executive director Elodie Daguzan in a statement to Rapaport News. “In [the] WDC’s own words, it is what we call ‘an industry proposal that is effective and implementable now and that leaves no one behind.’ Also, we understand that the statement made by ADPA is not against the WDC-facilitated protocol but rather against the G7’s objectives without engagement with African producers.”
Rio Tinto has launched the Beyond Rare Tender, an inaugural collection of 48 lots of polished fancy-colored diamonds.
The miner will offer 87 diamonds in total, including its legacy inventory of pink and red stones from the shuttered Argyle diamond mine in Australia and yellow diamonds from its Diavik site in Canada, it said on Tuesday.
The new collection is “a testimony to the ongoing demand for highly collectible natural diamonds,” said Sinead Kaufman, chief executive of Rio Tinto Minerals. “This carefully curated collection of rare jewels will be in strong demand by the world’s finest jewelers, collectors and diamond connoisseurs.”
Titled The Art Series, the invitation-only tender is inspired by the art world, the company said. The combined weight of the diamonds is 29.96 carats.
They include the following:
Seven diamonds consisting of Argyle pink stones and yellow Diavik ones, which the company says will be accompanied by bespoke artwork.
An offering of 11 matched pairs of colored diamonds.
Thirty single diamonds, including one distinctive fancy-red Argyle diamond.
The closure of the Argyle mine in Australia and the continued strong demand for exceptional fancy pink and red diamonds means the market for Argyle pink and red diamonds “have never been stronger,” said Patrick Coppens, general manager of sales and marketing for Rio Tinto’s diamonds business.
The 48 lots will be shown in Australia, Switzerland and Belgium, with bids closing on November 20.
