The 1,094-carat Seriti diamond recovered last September from Lucara’s Karowe mine, in Botswana, is now in Belgium, where it will be cut by HB Antwerp as part of an ongoing partnership.
HB, founded in 2020, cut the 1,758-carat Sewelo diamond and the 549-carat Sethunya diamond – both of which were recovered at Karowe and both of which were bought by Louis Vuitton.
Exact prices were not disclosed, although Lucara did say last month that the Sethunya and the 1,080 carat Eva Star, sold for a combined $54m. HB gave no details of a buyer for the Seriti.
Seriti is the world’s sixth largest rough diamond, and the sixth +1,000-ct diamond recovered at Karowe.
HB says it will use “groundbreaking technology, traceability, and expertise to unlock the full brilliance of nature’s most exceptional creations”.
That includes its proprietary Hyperloupe technologies, designed specifically for large (up to 6,000 carats) and complex diamonds.
HB has a 10-year contract with Lucara to cut all its +10.8-cts stones. They account for around 70 per cent of the miner’s revenue.
Botswana’s government signed on Tuesday a long-delayed diamond mining and sales agreement with Anglo American unit De Beers, the world’s leading diamond producer by value.
As part of the deal, Botswana’s share of the diamonds produced by Debswana, a 50-50 joint venture between the country’s government and De Beers, will increase from 25% to 50%. Botswana will receive 10 billion pula ($712 million) in development funding, in line with a provisional 10-year arrangement reached in 2023.
The agreement, in negotiations since 2018, also extends the mining licenses for Debswana until 2054. Previously, the licenses were set to expire in 2029.
The signing of the contract had stalled under former President Mokgweetsi Masisi but was prioritized by President Duma Boko, who took office last October.
Botswana, the world’s largest producer of rough diamonds by value, depends on the sector for the bulk of its national revenue. President Boko, however, has voiced concerns that the industry is not generating enough employment opportunities.
While Debswana’s diamond production accounts for 80% of Botswana’s exports, the country has struggled to diversify beyond mining. Despite a relatively high annual per capita income of $7,820 — exceeding that of oil-rich Gabon and South Africa, the continent’s biggest economy—job creation remains limited.
The deal comes at a crucial time for De Beers, as its parent company, Anglo American, considers spinning out the diamond business through a sale or initial public offering. Analysts warn that weak global diamond prices could complicate such a move.
Botswana remains integral to De Beers’ operations, supplying 70% of its annual rough diamonds. The government also holds a 15% stake in De Beers, underscoring the long-standing strategic partnership between the two parties.
Canada’s Lucara Diamond achieved record-breaking production in 2024, highlighted by the recovery of two exceptional stones at its prolific Karowe mine in Botswana.
The miner increased its processed ore to 2.9 million tonnes last year, up from 2.8 million tonnes in 2023. It also set a new milestone with the recovery of 807 “specials”—diamonds larger than 10.8 carats—compared to 602 in the previous year. These accounted for 7.6% of the total recovered carats, up from 5.3% in 2023.
The two most important diamonds recovered last year were the 2,488-carat Motswedi and the 1,094-carat Seriti diamonds, both unearthed at Karowe.
Motswedi, found in August, is the largest diamond recovered in the last century. Its name means “water spring” in the local Setswana language, symbolizing underground water surfacing to bring life and vitality.
The Seriti stone, unearthed in September, translates to “aura” or “presence”, reflecting cultural identity and legacy.
Lucara’s discoveries have continued this year, with the recovery of a1,476-carat non-gem diamond in January.
Revenue jump The company sold 399,215 carats in 2024, generating $203.9 million in revenue — an 18% increase from $172.4 million the previous year.
“Our world-class Karowe mine continues to set new benchmarks,” CEO William Lamb said in a news release. “The open-pit operations delivered yet another remarkable milestone with the recovery of our seventh 1,000+ carat diamond.”
Lamb also highlighted steady progress on Karowe’s underground expansion, with shaft sinking marking a major step forward. The project is expected to begin commercial production in early 2028.
Since it began operations, Karowe has yielded some of the world’s most remarkable diamonds, including the 1,758-carat Sewelô in 2019, the 1,109-carat Lesedi La Rona in 2015, and the 813-carat Constellation, also in 2015.
Karowe is also credited for having yielded Botswana’s largest fancy pink diamond to date, the Boitumelo.
The mine remains one of the world’s highest-margin diamond mines, producing an average of 300,000 high-value carats each year.
Botswana’s central bank left its main lending rate unchanged on Thursday, saying the economy was expected to operate below capacity and not generate demand-driven inflationary pressures because of a slump in the global diamond market.
The Bank of Botswana held its Monetary Policy Rate at 1.90% for the second policy meeting in a row. The rate is based on a seven-day instrument.
“The economy will contract this year primarily due to the downturn in the global diamond market and moderately recover next year,” central bank Governor Cornelius Dekop told a news conference.
The southern African country’s economy is largely dependent on the export of diamonds, and declining earnings from the precious stone have limited government spending.
The central bank also lowered its primary reserve requirement to 0% from 2.5% due to significantly reduced liquidity in the banking system.
Dekop said inflation was expected to average 2.9% in 2024 and 3.3% in 2025, compared with forecasts of 2.8% and 3.1% given at the bank’s previous monetary policy meeting in November.
The Bank of Botswana prefers inflation between 3% and 6% over the medium term. Annual inflation stood at 1.6% in October.
Botswana’s government is forecasting a recovery in the diamond market later this year, and a consequent expansion of the country’s economy.
It shrank by 3.1 per cent in 2024, but according to vice president and finance minister Ndaba Gaolathe it is now expected to grow 3.3 per cent in 2025.
“This growth outlook is premised on recovery of the diamond industry, which is expected in the latter part of 2025, and continued positive sentiment in the non-diamond mining sectors,” he said yesterday (10 February) in his budget speech for 2025/26.
Diamonds account for around 80 per cent of Botswana’s export earnings and a third of total budget revenues.
De Beers and the Botswana government have finally reached agreement on the long-term mining and rough sales deals.
But their joint venture Debswana reported sales for the first three quarters of 2024 were down by 52 per cent.
In December, Gaolathe warned that Botswana’s economy could contract by 1.7 per cent during 2024 as a direct result of the diamond. Slump.
But he predicted better times ahead, with an expected rebound in the diamond market driving overall growth in 2025.

De Beers, the world’s leading diamond producer by value, has concluded negotiations with the Botswana government on a new sales agreement and the extension of mining licenses for their joint venture, Debswana, until 2054.
The finalized agreement, the Anglo American unit said on Monday, follows discussions aimed at setting a new framework for the sale of rough diamond production from Debswana, a 50:50 partnership between De Beers and Botswana. The deal also secures the renewal of Debswana’s mining licenses, which were previously set to expire in 2029.
“Until the execution of these new agreements, the terms of the existing agreements will continue to remain in effect,” the diamond producer said.
Currently, 75% of Debswana’s diamond output is sold to De Beers. In 2023, the two parties reached a provisional 10-year agreement under which Botswana’s share of production was set to gradually increase to 50%.
The accord also established that Botswana’s state-owned diamond trading company was expected to receive 30% of Debswana’s production.
The government would also secure 10 billion pula ($712 million) in development funding as part of the deal. However, the deal stalled under the leadership of former President Mokgweetsi Masisi.
In January, newly elected President Duma Boko announced that his administration had reached an agreement with De Beers. Botswana, the world’s largest producer of rough diamonds by value, depends on the industry for the majority of its national revenue.
This new agreement comes at a pivotal time for De Beers as parent company Anglo American plans to spin off the diamond business through either a sale or an initial public offering. Analysts have noted that current depressed diamond prices may complicate efforts to finalize such a transaction.
Botswana remains a cornerstone of De Beers’ operations, accounting for 70% of its annual rough diamond supply. The government also holds a 15% stake in De Beers, underscoring the importance of the long-standing partnership between the two parties.
Botswana’s president Duma Boko, who swept to power in October elections, said his government has reached a diamond extraction and sales agreement with De Beers that will bring certainty to the gem-dependent economy.
Terms were finalized by midnight on Jan. 24 and will be announced soon, Boko said in an interview on Tuesday. The southern African nation is the world’s biggest producer of rough diamonds by value and the industry generates the bulk of its income. Most of Botswana’s gems are mined by Debswana, a venture between Anglo American Plc’s De Beers unit and the government.
“The issue with De Beers has been settled,” Boko said in Dar es Salaam, Tanzania, where he is attending an energy conference. He indicated last week at the World Economic Forum in Davos, Switzerland, that an agreement was imminent, and said he had followed through on his commitment to conclude it.
During his election campaign, Boko was critical of his predecessor Mokgweetsi Masisi’s handling of talks with De Beers to renew the more than half century alliance between Botswana and the world’s largest diamond firm. Masisi had caused De Beers to consider walking away from the deal, Boko said, and he sought to reopen talks.
Boko’s Umbrella for Democratic Change coalition unseated Masisi’s Botswana Democratic Party, which had led the country since independence from the UK in 1966.
The new agreement had not resulted in “any major changes, just a little tweaking of things here and there,” he said.
Under the provisional terms of a 10-year accord announced by Botswana’s previous administration in July, the state-owned diamond trader was to get 30% of Debswana’s output, while the government would secure 10 billion pula ($720 million) in development funding.
De Beers didn’t immediately respond to a request for comment.
An arid, underdeveloped nation at independence, Botswana has leveraged the discovery of diamonds in 1967 to build itself into the richest country per capita on Africa’s mainland, according to the World Bank.
Lab threat Still, a prolonged slump in the global diamond market and a challenge from lab-grown gems has hurt its economy. Boko said the agreement will restore certainty and economic growth will follow.
The country will focus on promoting its gems as natural and charging a premium for their provenance, marking them to show they have been mined in the country and their sale promotes development, he said. Diamond revenues in some other parts of Africa have been used to finance conflict.
“We appreciate the threat posed by lab-grown diamonds. I don’t want to give them the privilege of calling them diamonds. Diamonds are natural,” he said. “We will then market our diamonds in terms of their provenance and of the story behind the diamond.”
Botswana Diamonds has analysed and evaluated nearly 400 000 km of airborne geophysical and other exploration data using AI techniques and powerful computing, which would otherwise have been too big for timely analysis by humans.
In particular, the company has identified seven significant kimberlite targets on existing licences that have not been reported before.
The AI programme has also revealed compelling polymetallic targets in areas that are currently unlicensed.
Work is ongoing on these new areas of interest which now focuses on four main deposit types and 11 subtypes. These deposit types include elements such as gold, copper, silver, nickel, zinc and platinum group metals.
Botswana Diamonds used UK-headquartered Planetary AI’s ‘Xplore’ mineral prospectivity platform to perform the detailed analysis.
Xplore Platform is software that enables targeting of any element based on a plethora of geological and topographic information.
Botswana Diamonds chairperson John Teeling comments that these discoveries, in a few short months, are a major step forward in mineral exploration. One anomaly is especially intriguing to the company and the AI programme has reinforced the company’s belief that more diamond mines will be discovered in Botswana.
The company currently operates three diamond mines in Botswana and it also holds assets in South Africa.
Botswana’s central bank left its main lending rate unchanged on Thursday, saying the economy was expected to operate below capacity and not generate demand-driven inflationary pressures because of a slump in the global diamond market.
The Bank of Botswana held its Monetary Policy Rate at 1.90% for the second policy meeting in a row. The rate is based on a seven-day instrument.

Canada’s Lucara Diamond has dug up a 1,094 carat diamond from its Karowe mine in Botswana.
This is the sixth diamond weighing more than 1,000 carats to be recovered at the mine, and it comes only weeks after the recovery of a 2,492 carat diamond the second-largest diamond ever recovered.
“This remarkable stone bears striking similarities to the 692 carat diamond announced in August 2023, which was polished by HB Antwerp and yielded polished diamonds that sold for in excess of $13 million,” the company said in a press release.
“This newly recovered 1,094 carat stone will also be polished by HB Antwerp, as part of the ongoing partnership between the two companies,” Lucara said.
The Karowe mine has produced several large diamonds in recent years, including the 1,758-carat Sewelô in 2019, the 1,109 carat Lesedi La Rona in 2015, and the 813 carat Constellation, also in 2015. The mine is also credited for having yielded Botswana’s largest fancy pink diamond to date, the Boitumelo.
Botswana is the world’s largest producer of diamonds, and the trade has transformed it into a middle-income nation.
Karowe remains one of the highest margin diamond mines in the world, producing an average of 300,000 high value carats each year.
Shares of Lucara rose 8% by 11:40 a.m EDT in Toronto. The miner has a market capitalization of C$221 million ($162 million).
