Lucara names two largest diamonds found in 2024

Lucara Diamond has unveiled the names chosen of the two largest diamonds recovered this year at its prolific Karowe mine in Botswana.

The 2,488 carat diamond found in August has been named Motswedi, meaning “water spring” or “the flow of underground water that surfaces to bring life and vitality” in the local Setswana language.

The 1,094 carat diamond recovered in September is now known as Seriti, which translates to “aura” or “presence” in Setswana. The name carries deep cultural significance, reflecting identity and legacy.

Lucara said the two diamonds were not just geological phenomena, but a testament to the “incredible potential” of Karowe and the company’s innovative approach to diamond recovery.

“Each stone tells a story millions of years in the making, and we are humbled to be the custodians of these remarkable gems as they prepare to enter the global market,” president and chief executive officer, William Lamb, said in the statement.

To honor the community’s involvement, Lucara awarded the winner of the Motswedi naming competition 100,000 Pula (about $7,325), while the winner for Seriti received 50,000 Pula ($3,660). Both winners will also be invited to tour the Karowe mine.

Lucara said it was considering sale options for both diamonds.

Motswedi and Seriti are two of six diamonds weighing more than 1,000 carat that Lucara has recovered at its Karowe mine since operations began. These include 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.

Burgundy Sales “Bode Well for Recovering Diamond Market”

Burgundy Diamond Mines reported an increase in prices but a dip in revenue from its Ekati mine, in Canada, during Q4.

Sales held in October and December raised $47m and $46m respectively (total $93m) the Australia-based company said today (17 December) in its interim sales report and company update. Average prices per carat were $80 and $106 (all figures US dollars).

Total proceeds for the previous quarter, Q3, were $118m, with average prices down to $83 per carat in what it described at the time as a “soft diamond market”.

Kim Truter, Burgundy’s CEO, said the results “bode well for a recovering diamond market”.

He said prices at the December sale reflected a higher quality parcel of goods sold, and said there had been gains in the mid to large size categories, relative to the October sale.

Burgundy bought the Ekati mine, 125 miles south of the Arctic Circle, in Northwest Territories, last June for $136m from the Arctic Canadian Diamond Company and plans to extend its life by developing underground operations.

“The company looks forward to reporting the results of its mine life extension work at the Sable underground project and the Misery underground operation, in addition to an updated Fox underground prefeasibility study, commencing in Q1-2025,” Burgundy said.

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.

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.

Power Revolution: The Everlasting Diamond Battery

Scientists in the UK have produced the world’s first diamond battery.

They say they’re a safe and sustainable alternative to lithium ion – and will last for an incredible 5,000 years.

They look like a conventional watch battery, but are much thinner and destined to power pacemakers, hearing aids and other healthcare devices, as well as satellites, deep space missions and remote sensors.

Nuclear fusion experts at the government’s UK Atomic Energy Authority (UKAEA), working with the University of Bristol, have developed the ever-lasting batteries using lab grown diamonds and an ultra-thin slice of radioactive material, the isotope known as carbon-14.

Neil Fox of the School of Chemistry at the University of Bristol said: “Carbon-14 was chosen as a source material because it emits a short-range radiation, which is quickly absorbed by any solid material.

“This would make it dangerous to ingest or touch with your naked skin, but safely held within diamond, no short-range radiation can escape.”

The semiconductor properties of the diamond convert the radioactivity into electricity, and it’s so hard that it prevents the radioactivity from escaping.

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.
