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.

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.

5.72-ct Blue Diamond Sells for $8.8m

A 5.72 carat fancy intense blue diamond beat its high estimate and sold for $8.8m yesterday (10 December) at Christie’s New York.

The cushion brilliant cut VVS1 stone, set in a platinum ring with round diamonds, was the highlight of the Magnificent Jewels auction.

The price realized was $1,539,336 per carat. The pre-sale estimate was $6m to $8m.

The second highest price was for a pair of Harry Winston spinel and diamond earrings. They sold for $2,228,000â€”four times their high estimate of $600,000.

The sale raised a total of $49.2m, with 97 per cent of the 179 lots finding buyers.

Rahul Kadakia, Christie’s international head of jewelry, said: “Today’s sale in New York was a testament to the vibrant market for jewelry of the highest caliber with singular provenance.

“We were particularly pleased with the result of the top lot – a fantastic fancy intense blue diamond ring that sold for $8.8m.”

The Fancy Color Research Foundation gave the blue diamond a visual score of 8 out of 12 in its pre-sale analysis, noting its low color dispersion.

It said: “True Face-Up: Equivalent to that of a 9.15 carat which is ~59.9 per cent larger than the average

“Analysis: A Fancy Intense Blue Cushion brilliant-cut diamond, polished as a classic colorless diamond, probably manufactured during the 1960s or 1970s.

“The diamond’s inner-grade is very strong, and modifying its facet alignment could increase its saturation to vivid. No significant gray undertone is present in the color.”

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.

Rio Tinto’s Beyond Rare diamond tender delivers strong results

Diversified mining company Rio Tinto’s second Beyond Rare tender has achieved a strong result, underscoring the rarity and unique provenance of the diamonds on offer.

The auction, which featured some of the world’s most coveted natural fancy coloured diamonds, also showcased the continuing global demand for these rare treasures.

The collection, which comprises 76 diamonds across 48 lots, included an exceptional mix of pink, red, and violet diamonds from the now-closed Argyle diamond mine in Australia, as well as white and yellow diamonds from Rio Tinto’s Diavik mine in Canada.

For the first time, the tender also included seven “Old Masters”, notable historic diamonds from the Argyle mine, further elevating the event’s appeal to collectors.

The tender saw successful bids from 12 bidders spanning Australia, Europe, Japan, Hong Kong, the Middle East, Singapore, and North America.

“The continued strong global interest in highly collectible natural coloured diamonds and the resulting value creation, reflects their stature as works of art to be treasured for future generations,” commented Rio Tinto Minerals CEO Sinead Kaufman.

One standout lot, Lot 40, which featured a 4.04-ct pear-shaped pure white diamond from the Diavik mine, alongside two rare pear-shaped violet diamonds from the Argyle mine, was entrusted to Danish luxury jeweller Hartmanns. The company will work with Glajz, an Argyle Pink Diamonds Icon Partner, to create a one-of-a-kind heirloom jewellery piece from these diamonds.

“I am honoured to be creating a jewelled treasure that reflects each magnificent birthplace of these three esteemed diamonds – Argyle in the remote East Kimberley region of Western Australia and Diavik, just below the Arctic Circle on the frozen edge of the earth in Canada’s Northwest Territories,” said Hartmanns owner Ulrik Hartmann.

Rio Tinto’s Argyle diamond mine, which ceased production in November 2020, was the source of nearly entirely the world’s total supply of rare pink and red diamonds. With 37 years of production, Rio Tinto continues to manage the Argyle Pink Diamonds brand, facilitating sales of remaining inventory and collaborating with prominent jewellers globally.

In addition to owning the Argyle Pink Diamonds™brand, Rio Tinto is the majority owner and operator of the Diavik mine in Canada. The company also continues to explore new opportunities in the diamond sector, with a recent joint venture agreement with Endiama, the national diamond mining company of Angola, to explore the Chiri kimberlite in Angola’s Lunda Sul province.
