See The World’s Rarest Diamonds, Worth a Total of $100 million, in Abu Dhabi

Sotheby’s, in partnership with the Abu Dhabi Investment Office, is exhibiting extremely rare coloured diamonds at Bassam Freiha Art Foundation this week, in the biggest showcase of diamonds outside of the Smithsonian Museum in Washington DC.

All together, the spectacular diamonds are worth around $100 million. The largest flawless diamond in the world, the largest vivid orangey pink diamond ever graded, the second largest red diamond known to exist and several diamonds over 100 carats are included in the collection, which will be available for public view this Wednesday, April 9 and Thursday, April 10.

“The exhibition is incredibly exciting for the simple reason that to purely just have eight diamonds of this calibre in the same room is something that is worthy of one of the great museums in the world, and I can’t imagine that we will ever see this array together again,” says Paul Redmayne, Sotheby’s senior vice president for luxury private sales. “It is definitely a career highlight for me to see these stunning gemstones side by side, and I look forward to no doubt witnessing many a jaw drop as the public come through the doors.”

The star of the showcase is none other than The Mediterranean Blue. Weighing 10.03 carats, this Fancy Vivid Blue rarity has earned the highest GIA colour grading and a coveted Type IIb classification, an elite status held by less than 0.5 per cent of diamonds. Its cushion cut intensifies its liquid-like saturation, an electrifying depth that feels almost surreal. With an estimated value of $20 million, The Mediterranean Blue will be the highlight of Sotheby’s High Jewellery Sale on May 13 in Geneva.

“The Mediterranean Blue diamond on its own is an incredibly rare stone, and ticks so many of the boxes that you could look for: it is a connoisseur’s diamond, whilst also being infinitely wearable,” shares Redmayne. “The depth of the blue is unrivalled, and even to someone who knows nothing about diamonds, it’s clear to see what makes it so special.”

The diamond is a timeless symbol of love, power, beauty and status – but a captivating collection of this stature is awe-inspiring at an entirely different level; a once-in-a-lifetime experience in the UAE’s capital city, which Redmayne says marks an incredibly exciting moment in the city’s history. “This project further enriches the dynamic landscape of Abu Dhabi for both collectors and the general public,” he says.

Canada’s Big Three Mines Could Close Early

Canada’s three biggest diamond mines could be forced to close early, an economist has warned, amid the ongoing slump in prices.

Operators reported losses last year for Diavik, Ekati and Gahcho Kue, all in Canada’s Northwest Territories (NWT).

They are slated for closure as they reach the end of their lives – estimated at 2026, 2029 and 2030 respectively – but dwindling demand may render them uneconomic before those dates.

Graeme Clinton, an economist in Yellowknife, capital of NWT, told CBC, Canada’s national broadcaster : “I don’t think nearly enough is made of the state of the markets which are most important to our economy. These low prices could very well mean an early closure.”

He qualified his comments by saying that none of the miners had so far indicated that they’d bring forward their closing dates.

Diamond mining is key to NWT’s economy, representing over a quarter of its GDP, but miners have been hit hard by the downturn.

Rio Tinto’s Diavik mine lost CAD 127m (USD 94.6m) in 2024, Burgundy’s Ekati lost CAD 94.7m (USD 70.5m) and Mountain Province, minority-owner of Gahcho Kue lost CAD 81m (USD 60.0m).

Early closures would cost thousands of jobs, and would dent NWT’s economy.

Bombshell: Trump’s 26% Tariffs on Indian Exports

India’s diamond industry is in shock today after the US imposed 26 per cent reciprocal tariffs on all its exports.

That’s almost double the 13.3 per cent predicted by India’s Global Trade Research Initiative before yesterday’s news (2 April).

Traders, manufacturers, exporters and others in India’s diamond industry are still struggling to process the scale of the announcement, made by President Donald Trump in what he called his Liberation Day speech, outlining tariffs that would boost domestic industry and “make America wealthy again”.

He said US tariffs would be roughly half those charged by each of its trade partners. India charges the US 52 per cent, he said, a figure that includes currency manipulation.

“The [gems and jewellery] trade is expected to come at a standstill as US importers will assess whether to place orders with Indian jewellery exporters,” said Kirit Bhansali, chairman of the Gem and Jewellery Export Promotion Council, reacting to the news.

“The tariff is higher than expected,” Colin Shah, managing director of Kama Jewelry. “It is quite severe and will affect exports.”

The US represents over 30 per cent of all India’s gem and jewelry exports, worth $10bn a year. Exports of loose diamonds to the US which currently attract no import duty – and gold jewelry, which is charged at 5.5 per cent to 7 per cent. The US has a trade deficit of $46bn with India.

Trump announced a raft of tariffs on trade partners around the world, claiming the US had been losing out for decades.

“They (India) are charging us 52 per cent and we charge almost nothing for years and years and decades,” said Trump during his announcement.

For decades, the president said, the US “has been looted, pillaged, raped and plundered by nations near and far, both friend and foe alike”.

The White House said India imposed “uniquely burdensome” non-tariff barriers. Removing them would increase US exports by at least $5.3bn annually.

The US announced a baseline tariff of 10 per cent on all countries (except Canada and Mexico), to be implemented on 5 April. Additional tariffs (as high as 49 per cent for Cambodia) will be introduced on 9 April for targeted countries.

Swiss Watch Slump: Exports to China down 25%

Swiss watch exports slumped in February, down 8.2 per cent, with sales in China down by a quarter.

The Federation of the Swiss Watch Industry Exports (FHS) described it as a “marked slowdown in an uncertain climate”.

It follows a brief return to growth in January, when foreign sales rose by 4.1 per cent after a 2024 marked by steady decline.

China, the third biggest market for Swiss watches, saw sales plunge by 25 per cent year-on-year in February. Exports to Hong Kong, the second biggest market, fell by 12.5 per cent, and they were down 19.1 per cent to Japan.

In the US they fell 6.7 per cent, in marked contrast to a 16.2 per cent increase the previous month.

“Most of the main markets saw significant declines in February,” the FHS said in its monthly update. “Swiss watch exports fell back by 8.2% in February, despite a favourable base effect.”

The six biggest markets, representing just over half of all Swiss watch exports, recorded a combined decease of 12.5 per cent.

Mid-priced watches – CHF 500 to CHF 3,000 ($550 to $3,300) – suffered the biggest losses, down over 15 per cent by value.

Diavik recovers 158.20 carat ‘miracle of nature’ diamond

One of the largest gem-quality yellow diamonds ever discovered in Canada, has been unearthed from Rio Tinto’s Diavik Diamond Mine.

The 158.20-carat rough diamond is one of only five yellow diamonds weighing more than 100 carats ever unearthed at Diavik in its 22-year history, stated a release.

Diavik’s production primarily consists of white gem quality diamonds, with less than one percent of its production yielding rare yellow diamonds.

Diavik Diamond Mines Chief Operating Officer Matt Breen stated: “This two-billion-year old natural Canadian diamond is a miracle of nature and testament to the skill and fortitude of all the men and women who work in Diavik’s challenging sub-Arctic environment.”

Patrick Coppens, sales and marketing GM for Rio Tinto’s diamonds business, stated: “The beauty and purity of Diavik diamonds continues to excite passions amongst all who see them and we look forward to following the onward journey of this very special diamond.”

Diamond miner Lipari begins trading on Cboe Canada

Canadian diamond miner Lipari Mining has officially begun trading on the Cboe Canada stock exchange following the completion of its recently announced reverse takeover.

“Listing on Cboe Canada marks a major milestone in our company’s growth,” CEO Ken Johnson stated in a news release Monday, adding that the exchange’s global footprint would allow the company to broaden its shareholder base and increase market visibility.

Shares of Lipari Mining traded at C$0.57 at Monday’s open, for a market capitalization of approximately C$83.7 million ($58.5 million).

Formerly known as Golden Share Resources, the company announced last month that it is acquiring Lipari Diamond Mines (LDM) and its assets in Angola and Brazil through an RTO, following which LDM shareholders would own nearly all (96.7%) of the combined company’s shares.

Prior to closing the transaction, LDM raised approximately $3.62 million through a private placement of subscription receipts to support the future development of its two diamond assets.

In Angola, Lipari owns a 75% equity interest in Tchitengo diamond project, encompassing 30 known kimberlite deposits. The Tchiuzo kimberlite represents the most developed, having already been taken to pre-feasibility by Sociedade Mineira de Catoca and ALROSA in 2013 after spending a reported $35.6 million.

In an earlier news release, CEO Johnson said the company has planned a bulk sampling program at Tchiuzo to follow up on the confirmatory drilling completed by LDM last year. This is targeted to produce a representative parcel of rough natural diamonds for evaluation and making a production decision.

Lipari also owns 100% of the Braúna diamond mine located in the state of Bahia, Brazil. Since entering commercial production in July 2016, the mine has produced nearly 1.2 million carats of natural rough diamonds from 6.54 million tonnes of kimberlite mined, for an average production grade of 18.2 cpht. Operations are now focused on the transition of the mine from an open pit to an underground operation.

According to Johnson, the mine is ramping back to full capacity, with the transition to underground mining largely completed. “Our first sale of diamond production from our underground operation is expected in April,” he added.

Revenue Down, Stores Closed at Chow Sang Sang

Chow Sang Sang suffered a net loss of 74 of its 1,032 stores last year, amid weak demand, record-high gold prices and an economic slowdown in China, as well as Hong Kong and Macau.

China’s third biggest jewelry retailer (by revenue) saw sales for the year to 31 December 2024 fall by 15 per cent to HKD 21.18bn ($2.72bn).

Same-store sales were down 38 per cent on the mainland and 24 per cent in Hong Kong and Macau, primarily due to a drop in diamond demand. Profit slid 20 per cent to HKD 805.6m ($103.6m).

Chow Sang Sang did not rule out further store closures. “Under the present economic climate, it would be prudent to continue our physical store network consolidation,” it said its Annual Results.

“In 2024, uncertain economic conditions coupled with record-high gold price exerted significant pressure on jewellery demand in both Mainland China, and the Hong Kong and Macau markets, resulting in a 15 per cent year-on-year decline in turnover.

“Continuing our efforts to consolidate the store networks, we opened 48 and closed 122 stores, mostly in Mainland China.”

The Future of Laboratory-Grown Diamonds

The Future of Laboratory-Grown Diamonds: Market Trends and Industry Outlook

Laboratory-grown diamonds have experienced rapid growth over the past decade, transforming the diamond industry by offering an ethical and cost-effective alternative to natural diamonds. With advances in technology, increasing consumer acceptance, and shifting industry dynamics, lab-grown diamonds are poised to play an even greater role in the future of the jewelry market. But what does the future hold for this evolving sector? Let’s explore key trends, challenges, and opportunities shaping the future of lab-grown diamonds.

The Rise of Laboratory-Grown Diamonds

The Future of Laboratory-Grown Diamonds https://labtika.com.au/

The market for lab-grown diamonds has expanded significantly in recent years, driven by improvements in production techniques such as Chemical Vapor Deposition (CVD) and High-Pressure High-Temperature (HPHT) methods. These technological advancements have enhanced the quality, size, and affordability of synthetic diamonds, making them increasingly appealing to consumers and jewelers alike.

According to industry reports, lab-grown diamonds now account for a growing percentage of global diamond sales, with some estimates suggesting they could reach 10-15% of the market within the next few years. As consumer awareness continues to rise, major retailers and brands have started incorporating lab-grown diamonds into their collections, further legitimizing their place in the luxury jewelry sector.

Sustainability and Ethical Considerations

One of the strongest selling points for lab-grown diamonds is their sustainability. Unlike mined diamonds, which require extensive land excavation and energy consumption, lab-grown diamonds offer a more environmentally friendly alternative. Many consumers, particularly younger generations, are increasingly drawn to the ethical benefits of lab-grown diamonds, as they avoid the environmental and human rights concerns associated with traditional diamond mining.

In response, major diamond producers have begun investing in sustainability initiatives to differentiate their products, but the perception of lab-grown diamonds as the more responsible choice continues to gain traction. Companies that focus on transparency, renewable energy, and carbon-neutral production methods are likely to see significant growth in this space.

Market Challenges and Consumer Perceptions

Despite their advantages, lab-grown diamonds face challenges that could impact their long-term viability. One of the primary concerns is price depreciation. Unlike natural diamonds, which historically retain value over time, lab-grown diamonds are subject to rapid price declines due to the scalability of production. This could impact their investment appeal and influence consumer purchasing decisions.

Another challenge is brand positioning. While some consumers fully embrace lab-grown diamonds as a legitimate alternative, others still view them as an inferior substitute to natural diamonds. The luxury market thrives on exclusivity, and natural diamonds continue to carry a certain prestige that lab-grown stones may struggle to match.

Industry Response and Future Outlook

Recognizing the shifting landscape, traditional diamond companies have taken various approaches to the rise of lab-grown diamonds. Some, like De Beers, have launched their own lab-grown diamond lines at competitive prices, while others focus on marketing the rarity and uniqueness of natural diamonds. As the industry adapts, we may see a clearer segmentation between high-end natural diamonds and more accessible, everyday lab-grown options.

Looking ahead, technological advancements will continue to shape the future of lab-grown diamonds. Improvements in production efficiency, clarity, and customization could further increase consumer demand. Additionally, the growing acceptance of lab-grown diamonds in sectors beyond jewelry—such as electronics, quantum computing, and industrial applications—will expand their market potential.

The future of lab-grown diamonds is bright, with continued growth expected in both the jewelry and industrial sectors. While challenges remain, the ethical appeal, affordability, and technological advancements in lab-grown diamonds position them as a formidable force in the market. As consumer preferences evolve, the diamond industry will need to adapt, ensuring that both natural and lab-grown diamonds coexist in a dynamic and competitive landscape.

Botswana’s Economic Outlook Now Negative, says S&P

Botswana's economy is heavily reliant on diamonds.

Botswana’s economic outlook has been downgraded from stable to negative by S&P Global Ratings (S&P) on account of low demand for diamonds.

It forecasts a steep rise in government debt unless there is a substantial increase in diamond prices or significant fiscal intervention.

Botswana’s economy is heavily reliant on diamonds. They account for around 80 per cent of its export earnings and a third of total budget revenues.

De Beers and the Botswana government finally reached agreement last month on the long-term mining and rough sales deals, but sales by their joint venture, Debswana, were down by 52 per cent for the first three quarters of 2024, and there a few signs of a sustained recovery in demand.

Despite downgrading its economic prospects, S&P left Botswana’s long-term foreign and domestic currency sovereign credit rating unchanged at BBB+ and its short-term rating at A-2.

“The negative outlook is on account of S&P’s expectation that weak global demand for diamonds and depressed prices will continue to suppress Botswana’s exports and fiscal position, therefore, delaying government’s fiscal consolidation agenda and the rebuilding of buffers,” said the Bank of Botswana in a statement.

It highlighted the fact that S&P said the newly-elected government’s commitment to reducing unemployment, diversifying the economy and increasing social support, while maintaining fiscal prudence, also had a positive impact to the ratings.
