Botswana Diamonds uncovers new kimberlite targets using AI

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.

India’s Government Urged to Adopt Lab Grown Rules

India’s government is being urged to adopt the same rules on lab grown terminology as the US.

The GJEPC (Gem & Jewellery Export Promotion Council) says its 7,000-plus members are now required to adhere to the rules introduced by the US Federal Trade Commission (FTC) in 2016 and amended two years later. They have also been adopted by many other countries.

“Since India’s gem and jewellery trade has unanimously accepted the FTC’s new definition with respect to diamonds, we urge the Indian government and ministries to accept, adopt and adapt the same to existing consumer laws of our country.”

The FTC provides detailed guidance on exactly what forms of words can be used. It says: “If you sell laboratory-created diamonds, you should tell consumers that they are not mined diamonds by describing them as “laboratory-grown,” “laboratory-created,” “[manufacturer name]-created,” or some other word or phrase of like meaning so as to disclose, immediately preceding the word “diamond” and equally conspicuously, the nature of the product and the fact it is not a mined diamond.”

Smit Patel, convener of the GJEPC’s lab-grown diamond panel, said: “We have urged the government to align with the advancements and economic significance of lab-grown diamonds by adopting a forward-looking policy framework.”

The Indian government says its Central Consumer Protection Authority (CCPA) has organized a stakeholder consultation on consumer protection for the diamond sector, following representations from the GJEPC.

10 Carat Burmese Ruby Ring Sells for USD $5.5 Million at Sotheby’s Auction

A stunning 10.33-carat Burmese ruby fetched an impressive $5.5 million at Sotheby’s Magnificent Jewels auction in New York, following a heated six-minute bidding battle between two phone bidders and one participant in the saleroom. The final sale price more than doubled its high estimate.

This cushion-shaped, untreated ruby, set in a ring alongside two pear-shaped diamonds, emerged as the highlight of the 96 lot auction, which achieved a total of $30 million. Notably, 92% of the lots were sold, with 70% exceeding their high estimates.

The auction underscored a strong appetite for rare colored gemstones, exceptional white and colored diamonds, and signed pieces from renowned names like Graff, Van Cleef & Arpels, and Boivin.

Indian Digger’s Diamond Fetches $111,000

A 19.22 carat diamond, recovered from a shallow mine by a part-time digger in India’s Panna district, sold at auction for $111,000 (Rs 93,79,360).

It was one of 29 diamonds sold by the Panna Diamond Office, as part of a deal in which farmers and laborers rent small patches of land from the government. The other 28 stones raised just over $28,000 between them.

Many of the stones recovered have failed to find buyers at the three-monthly auctions over the last two years, but demand picked up at this latest event, with large crowds of bidders in attendance.

Panna is said to be home to 1.2m carats. Part-time miners pay $2.70 for the rights to dig a 25ft square patch there and diamond finds are quite common.

In February 2022 a part-time prospector dug up a 26.11-carat diamond which later sold for at auction for $193,000.

Shutdown for 15,000 Diamond Workers after Boss Suffers Stroke

Maruti Impex, described as one of the world’s biggest manufacturers of small natural diamonds, is halting operations, and has advised its 15,000 workers to seek employment elsewhere.

The company’s founder, Suresh Lakhani, aged 45, suffered a stroke three months ago and remains in a coma.

He’s been the driving force behind the business, which he launched in 1995 when he was just 16 years old. He is said to be the sole decision maker.

The future of Maruti Impex, which operates over 100 units, directly and indirectly, in Surat, Bhavnagar, Amreli, and Junagadh, is now uncertain.

Staff were informed of the closure by audio message, just as diamond units re-open after the Diwali break.

They received salaries up to the holiday, but have been told it’s not clear when operations could resume. The company made mention of “three or four months”.

Family members stepped in short term following Lakhani’s stroke, but have reportedly decided to pause operations because of weak market conditions.

Times of India quotes Dinesh Navadiya, chairman of the Indian Diamond Institute, as saying: “Without his (Lakhani’s) leadership and given the current challenging market conditions, the management is unable to continue operations.”

Lakhani describes himself on LinkedIn as a “self-made entrepreneur and philanthropist who has built a successful global business – “Maruti Impex” from scratch. Maruti Impex is one of the largest companies in the world in cut and polished diamonds.”

Botswana holds main interest rate as diamond slump saps economy

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.

Surge in Gold Prices Hits Luk Fook Revenue

*Luk Fook Jewellery storefront in Hong Kong.*

Luk Fook reported a 27 per cent slump in its half-year revenue and the closure of 175 of its 3,500-plus retail jewelry stores amid a surge in gold prices and weak consumer demand.

Earnings for the six months to 30 September were down to $700m. The Hong Kong-based jewelry chain blamed: “various challenges including macroeconomic uncertainties, further rising gold prices and cautious consumer sentiment, coupled with a high base effect”.

Luk Fook said the sharp rise in gold prices – an increase of 23 per cent during the six months – affected consumer sentiment, resulting in a 24 per cent drop in the sales of gold and platinum products. Overall same stores sales were down 34 per cent.

CEO Wong Wai Sheung said: “Although the spike in gold prices may affect sales performance, an increase in profit margin will help mitigate the impact of the decline in sales.

“Sales of the gold products are expected to resume to the normal levels after consumers adapt to the high gold prices.

Gross profits for the six months were down 14 per cent to $228m, net profit fell 56 per cent to $54m.

In March, Luk Fook reported a 28 per cent increase in revenue, driven by a post-Covid influx of tourists.

Sanctioned Russia Sells Shares in Angolan Diamond Mines

Angola has announced that Russian shares in two of its major diamond mines have been sold to an Omani-backed fund as a result of international sanctions, a government official said.

Russia’s diamond giant Alrosa was until now a joint owner of Angola’s Catcoa mine, the fourth-largest in the world, and Luele mine, in partnership with the southern African nation’s state-owned company Endiama.

The European Union imposed sanctions on Alrosa, also state-owned, and its CEO in January as part of a ban on diamond imports over the Ukraine war.

This led to “a block on the commercialization” of diamonds from Catcoa and Luele mines, Angola’s Minister of Mineral Resources and Petroleum Diamantino Azevedo said Thursday.

After “negotiations between the Angolan and Russian governments, as well as between Endiama and its partner,” Alrosa has now “officially ceased operating in Angola,” Azevedo said.

The company has been “replaced by Maden International Group, a subsidiary of the Sovereign Fund of the Sultanate of Oman,” the minister added.

He said the transition process was “already underway and should be conducted swiftly.”

The sale comes as the United States President Joe Biden was expected to travel to Angola on Dec. 2.

The visit, his first to Africa, underscores the strategic importance of the oil and mineral-rich country where a massive U.S.-led project is underway to export critical minerals.

Botswana to become certifier in G7 Russian diamond ban

Major African diamond producer Botswana will join Antwerp as an origin certifier of rough diamonds for export to the G7 which banned imports of Russian stones from the start of this year, a joint statement said on Wednesday.

The addition of Botswana looks set to salvage implementation of the ban. The initial system would have seen all diamonds go through Europe’s diamond hub in Antwerp for verification, backed by a new tracing system.

African diamond producers Angola, Botswana and Namibia, as well as diamond miner De Beers, had said the mechanism was unfair and would hurt their economies.

“Botswana and the G7 diamond technical team are now crafting a roadmap to address any identified gaps, aiming to have the export certification node fully operational in Botswana as soon as possible next year,” the statement said.

The Group of Seven (G7) nations ban on direct Russian diamond imports took effect on Jan. 1, followed by a ban on Russia-origin diamonds via third countries from early March.

The tracing system was meant to be up and running by Sept. 1, but the EU delayed the implementation to March 2025.

De Beers to Cut Sightholder Numbers

De Beers says it will further reduce the number of sightholders, in a move designed to build partnerships that “create value”.

The emphasis will be on quality rather than quantity, CEO Al Cook told the Facets 2024 conference in Antwerp yesterday (26 November).

De Beers wrote to its 69 current sightholders last month advising them that a new supply agreement, as of January 2026, would be determined by an objective selection and allocation process. It declined to comment at the time.

“There will be some partnerships around the polished side, some partnerships around the rough side, some partnerships around dealing, some partnerships that go all the way into retail, but every partnership must create value, and that’s really important for all of our industry going forward,” Cook told the conference.

De Beers last reduced the number of sightholders in January 2021, when it introduced new contracts dividing buyers into three categories – dealers, manufacturers and integrated retailers.

The number of De Beers sightholders peaked at around 350 in the 1970s. It had halved by 2001 and was further reduced in subsequent changes to the client structure.
