De Beers Boss Says Trump’s Diamond Tariffs Do Nothing for U.S. Jobs

The diamond world is facing fresh turbulence following the U.S. government’s decision to impose tariffs on imported diamonds — a move that De Beers CEO Al Cook says does nothing to support American jobs or the economy.

In an exclusive interview with the Financial Times, Cook made it clear: “There are no U.S. diamond mining jobs to protect.” He stressed that these tariffs don’t create employment or benefit the domestic industry — instead, they act as a consumption tax that ultimately punishes the American public.

A Tax on Love, Not a Boost to Industry
The U.S. remains the largest market for diamond jewellery, accounting for about half of global demand, yet it has no significant commercial diamond mining of its own. Every diamond on American soil has been imported — meaning the 10% blanket tariff on all imports, introduced by President Donald Trump, hits the diamond trade especially hard.

Unlike many raw materials that were exempt from the tariffs, diamonds were left out, intensifying the impact on a sector already grappling with declining demand and competition from synthetic alternatives.

According to Cook, the result has been immediate: the trade in natural diamonds briefly ground to a halt. The World Diamond Council echoed his warning, stating that $117 billion in annual revenue and over 200,000 U.S. jewellery jobs could be at risk if diamonds aren’t removed from the tariff list.

“Tariffs on diamonds are not protecting American industry,” Cook emphasised. “They’re just increasing the cost of engagement rings, anniversary gifts, and other sentimental purchases.”

Global Trade Routes Disrupted
What makes diamonds unique is their complex, high-value supply chain. They’re small, easy to transport, and often pass through multiple countries — from mines in Botswana and Angola, to polishing hubs in India, and finally into U.S. jewellery stores. Tariffs disrupt that finely tuned system.

This comes at a particularly sensitive moment for De Beers, as parent company Anglo American prepares for a sale or initial public offering (IPO) of the diamond giant. Despite industry challenges, De Beers is pushing ahead with IPO plans that could launch by early next year.

But the company is feeling the pain too: first-quarter revenue dropped 44% year-on-year to $520 million, reflecting both lower prices and reduced demand. Anglo American has also written down De Beers’ value by $4.5 billion over the past two years.

Hope on the Horizon?
Still, Cook remains optimistic. He believes that over time, U.S. tariffs on diamonds will be lifted. The American government has already granted tariff exemptions for items like smartphones and car components, and Cook is confident natural resources like diamonds will follow suit.

Adding to that optimism are positive developments in U.S.–India trade talks. India polishes over 90% of the world’s diamonds, making it a key link in the supply chain. A favourable trade agreement between Washington and New Delhi could ease the pressure and offer the diamond sector a much-needed reprieve.

In the end, the message from De Beers is clear: Tariffs on diamonds don’t help American workers or industry — they just make life more expensive for consumers. As negotiations progress and the global market adjusts, the diamond world will be watching closely to see whether policymakers come to the same conclusion.

Rethink Yellow Diamond Jewels: How Yellow Diamonds Get Their Colour

Yellow diamonds are making a stylish comeback. Whether offering a warm, earthy glow or a vibrant pop of colour, these fancy-coloured stones bring a fresh, contemporary edge to fine jewellery. They can be worn as neutrals, used as centrepieces, or layered for subtle impact—making them as versatile as they are striking.

The colour in yellow diamonds is the result of nitrogen atoms bonding with carbon within the diamond’s crystal lattice. This bond subtly alters the diamond’s atomic structure, changing the way it interacts with light. Specifically, it absorbs the blue part of the visible spectrum, allowing yellow tones to dominate. The Diamond Certification Laboratory of Australia (DCLA) grades yellow diamonds based on their colour intensity, classifying them as light, intense or vivid. The deeper and more saturated the yellow, the rarer and more valuable the diamond. Curiously, the lighter tones are often more affordable than white diamonds, making them an attractive alternative for those seeking something both elegant and unique.

Why Designers Are Embracing Yellow Diamonds

Jewellery designers are increasingly drawn to yellow diamonds for their warmth, individuality, and unexpected elegance. These stones challenge the norm, offering something joyful and radiant while still being refined. As the jewellery world moves beyond the conventional, yellow diamonds are gaining traction as centrepieces with personality.

How to Wear Yellow Diamonds

Once your collection includes the classics such as white diamond hoop earrings, tennis bracelets, stacking rings or a line necklace it’s easy to introduce a splash of colour. Yellow diamonds pair beautifully with white or rose gold and work well layered with other tones. Go bold with vibrant yellow bangles and cocktail rings, or opt for a more understated approach with a mix of pale-yellow and Champagne diamonds, as seen in Sethi’s neutral-toned confetti styles.

Yellow Diamonds: The Emerging Trend in Engagement Rings

More couples are seeking engagement rings that reflect their personal style rather than adhering to tradition. Yellow diamonds especially those in softer or more earthy tones offer a refined, alternative aesthetic that still feels timeless and romantic.

One designer, Root, recalled a client who brought him a family heirloom: a pear-shaped yellow diamond. He combined it with a matching white diamond to form a heart-shaped engagement ring. Initially, clients were hesitant about yellow diamonds, unsure whether they carried the same prestige. That perception is changing rapidly.

Designer Lau echoes this sentiment. “As our view of what defines a high-quality diamond evolves, I find myself drawn to warmer tones and even imperfect shapes, they feel authentic and special,” she explains. Yellow diamonds are increasingly favoured for their character, individuality, and natural charm.

Why Yellow Diamonds Are Here to Stay

There’s an undeniable joy and brightness that yellow diamonds bring. Whether in soft pastel shades or vivid canary tones, they evoke a feeling of sunshine and optimism, something many people are seeking in their jewellery today.

As the desire for unique and meaningful designs continues to grow, yellow diamond engagement rings are well-positioned to become the next generation’s classic. After all, who can resist a jewel that radiates light, joy, and a touch of the unexpected?

Discover the magic of yellow diamonds, your perfect piece may be one sunny sparkle away.

Botswana economy hit hard as diamond slump deepens

Botswana is bracing for deeper spending cuts and a widening budget deficit as a prolonged slump in diamond demand pressures its economy, even as the country signals interest in expanding its stake in diamond giant De Beers.

Vice President and Finance Minister Ndaba Gaolathe said the government is preparing to make “drastic” fiscal adjustments to stay afloat, including slashing expenditures and boosting tax revenues.

“The first thing we need to do, obviously, is to live within our means,” Gaolathe said in Washington. “That means cutting spending — doing away with what we believe is some of the fat.”

Diamonds make up a third of Botswana’s revenue and lead its exports, but a prolonged drop in global demand since mid-2023 has forced the government to raise its budget deficit forecast to 9% of GDP — the highest since the pandemic. The downturn has also led to a 3% contraction in the economy this year.

With foreign reserves under pressure, officials plan to cut costs by trimming the government vehicle fleet and curbing travel. They’re also moving to boost revenue through stricter tax enforcement and a new digital transaction levy set to launch in September.

Despite fiscal stress, Gaolathe said Botswana is reluctant to seek financing on international markets, preferring concessional loans. “Let’s borrow where it’s cheapest,” he said.

Bigger De Beers stake
The diamond downturn has also accelerated changes in the industry. Anglo American (LON: AAL), which owns 85% of De Beers, has been seeking a buyer for the iconic diamond company. Botswana, which holds the remaining 15% and is De Beers’ primary diamond source, says it wants a greater say in the sale.

“We are very confident that partners are coming forward,” Gaolathe told Bloomberg, noting interest from countries, funds and companies with “deep interest” in the industry. Botswana wants any new owner to be financially strong and committed to the diamond business long-term — and said it is open to increasing its stake to as much as 50%.

The government and De Beers recently signed a 10-year deal to fund global marketing aimed at reviving demand for natural diamonds, which have been losing ground to lab-grown alternatives. New US tariffs on Botswana’s diamonds have since added uncertainty to any near-term rebound.

“High tariffs on our diamonds will have a deleterious effect on us,” Gaolathe warned. The Bank of Botswana expects only a “muted recovery” this year.

US Jewelry Sector Shrinks Again in Q1

The decline in the US jewelry sector continues, with yet another drop in the number of retail, wholesale and manufacturing businesses.

The total number fell by 3.4 per cent – just under 800 businesses – to 22,330 year-on-year, according to the latest update from the Jewelers Board of Trade (JBT), which provides commercial credit information. The figures take account of both closures and new business openings.

The figure for the previous quarter, Q4 2024, was -3.2 per cent, and for Q3 2024 it was -3.3 per cent, indicating a steady rate of decline.

The biggest fall in Q1 2025 was among jewelry manufacturers, down 4.6 per cent to 2,119. The number of retailers fell 3.5 per cent, down to 16,959 and the number of wholesalers fell 2.5 per cent to 3,252.

JBT reported the opening of 68 new retail jewelers in the US during Q1.

Signs of Stabilization: “Mild Decline” for Fancy Color Prices

Prices of fancy color diamonds slipped by “only 0.3 per cent” in the first quarter of this year, according to the Fancy Color Research Foundation (FCRF).

Concerns over the impact of US tariffs were counter-balanced, to some extent, by what it called “signs of market stabilization”.

In Q4 of 2024 the Fancy Color Diamond Index fell by 1.1 per cent, and in the full year 2024 prices suffered their biggest annual fall since FRCF launched the Index in 2014.

In its quarterly update the FCRF noted that despite anxieties about Trump’s proposed tariffs (currently on hold for 90 days) they may actually create a shortage of color diamonds in the US market, which could serve to drive prices up.

“While the headline number shows a mild quarterly decline, the underlying data tells a more optimistic story: certain categories have stabilized, and volatility across others has significantly slowed,” the FCRF said.

“Which may set the stage for a potential rebound in select categories throughout upcoming quarters.

The FCRF also said that GIA’s decision to halt overseas submissions to its US labs, following the tariff announcement, means fancy color stones are being graded in Hong King instead, which is slowing the supply chain.

Yellow fancy color diamonds (all sizes and intensity) suffered the biggest losses in Q1 2025, down by 0.7 per cent (following on from a 2.2 per cent drop the previous quarter). Blues were down 0.5 per cent and pinks just 0.1 per cent.

Roy Safit, CEO of the New York-based FCRF, said: “While global trade anxieties – particularly around renewed US tariff proposals – have undoubtedly created caution across luxury sectors, the fancy color diamond market remained impressively composed.

“In fact, given the sharp rhetoric around import duties and reshoring, many expected a more dramatic correction. Instead, the data shows a contained, strategic repositioning. It speaks to the market’s growing maturity and the defensive appeal of vivid color diamonds.”

JAR Collection set to Fetch $3m

A collection of 21 pieces by the celebrated jeweler JAR (Joel Arthur Rosenthal) is expected to sell for at least $3m at Christie’s Geneva.

It’s described as “one of the largest and most important private collections of works by the visionary designer”.

JAR is one of the most sought-after contemporary jewelers, known for his use of unconventional materials and techniques, and for drawing on flora and fauna as his inspiration.

His exclusive boutique, in Place Vendome, Paris, admits clients only by personal approval or recommendation and produces just 70 or 80 pieces a year.

The collection – A Bouquet of Gems: A Superb Collection Of Jewels By JAR – will be offered for sale at the Magnificent Jewels sale on 14 May.

They were acquired for a single private collector in the early 2000s and 2010s and none of them has previously appeared on the market or at auction.

Highlight of the sale is the 2009 sculptural diamond Apricot Blossom bracelet (pictured) with an estimate of $340,000 to $570,000.

A multi-gem chain necklace of round brown diamonds, emeralds, tourmalines, tsavorite spessartine garnets, peridots, purple, orange, pink sapphires and sapphires, topazes, fire opals, rubies, pink and purple spinels, amethysts, and aquamarines, has an estimate of $285,000 to $400,000.

And a 2006 ring, with a 6.36-carat cushion modified brilliant-cut diamond, and black diamonds, is offered with a $160,000 to $230,000 estimate.

India’s Polished Diamonds Export Down 17%

India’s polished exports fell by almost 17 per cent in the fiscal year ending March 2025, to $13.29bn, according to the Gem and Jewellery Export Promotion Council (GJEPC).

That’s among the lowest annual export figures for two decades, although not, as widely reported, the lowest of all. The GJEPC figure for 2005 was $12.3bn, up from $10.3bn in 2004. By comparison 2023/4 foreign sales totaled $15.97m.

Overall gem and jewellery exports fell 11.7 per cent in 2024/5 to $28.5bn, the lowest figure in four years.

But there are signs of a recovery, with polished diamond exports for March showing a year-on-year decline of just 0.76 per cent to $1.16bn and gems and jewelry actually growing 1 per cent to $2.58bn.

“The decline in gems and jewellery exports is mainly due to the continuous dip in demand in China as well as the US, India’s key export markets, due to the ongoing geopolitical tensions,” said GJEPC Chairman Kirit Bhansali.

“Also, the correction in rough diamond prices by 10-15 per cent impacted the value, causing the overall decline in exports.”

The Golconda Blue: The Largest Fancy Vivid Blue Diamond Ever Seen at Auction

Christie’s is preparing to showcase something truly extraordinary — The Golconda Blue, a 23.24 carat Fancy Vivid Blue diamond, set to headline the Magnificent Jewels auction in Geneva on 14 May. Held at the Four Seasons Hotel des Bergues, this remarkable stone carries an estimate of between $35 million and $50 million.

Mounted in a ring designed by the legendary JAR, The Golconda Blue is not only the largest Fancy Vivid Blue diamond ever offered at auction — it’s also one of the rarest and most historically significant diamonds in existence.

Its journey through history is as dazzling as the stone itself. Originally owned by Yeshwant Rao Holkar, the Maharaja of Indore — a prominent patron of art and fine jewellery in the 1920s and 1930s — the diamond was first set into a bracelet by Chaumet in 1923. A decade later, Mauboussin transformed it into a necklace worn by the Maharani, immortalised in a striking portrait by Bernard Boutet de Monvel.

In 1947, the diamond was acquired by none other than Harry Winston, who later sold it as a brooch to the Maharaja of Baroda. After years of being held privately, The Golconda Blue is now returning to the public eye for the first time in decades.

Rahul Kadakia, Christie’s international head of jewellery, called it “a once-in-a-lifetime opportunity,” noting the auction house’s long history with legendary Golconda diamonds such as the Archduke Joseph, the Princie, and the Wittelsbach.

The term Golconda itself refers to the legendary diamond mines of Eastern India, famous for producing some of the world’s most luminous, transparent, and pure gems. Among them are historic stones like the Koh-i-Noor, the Hope Diamond, and the Darya-i-Nur — and now, The Golconda Blue joins this rarefied list.

This sale is not just about a diamond. It’s about history, heritage, and the timeless allure of one of nature’s most breathtaking creations.

Petra Diamonds delays sale amid US tariffs uncertainty

Tender of diamonds from the Williamson mine in Tanzania proceeded as planned.

Africa-focused Petra Diamonds has postponed a scheduled sale of about 200,000 carats of diamonds from its Cullinan mine in South Africa, citing uncertainty over the impact of new US tariffs.

Last week, US President Donald Trump announced sweeping import tariffs ranging from 10% to over 100%, including a 30% duty on many South African goods. The move has injected volatility into the global diamond market.

Petra, which holds the world’s third-largest diamond resource, said the decision to delay the Cullinan sale aims to secure stronger market prices once the tariff situation becomes clearer. The sale had been expected to generate approximately $18 million in revenue.

Despite the disruption, the company managed to complete sales from its Finsch mine in South Africa and the Williamson mine in Tanzania before the tariffs were introduced.

South Africa remains one of the largest diamond exporters to the US, alongside India.

So far in the 2025 financial year, Petra has earned $103 million from rough diamond sales, down from $138 million during the first five tenders of the previous year.

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.
