Graff Diamond Ring Steals the Show at Freeman’s Important Jewellery Auction

Alrosa Upbeat, Despite Tariffs and Lab Growns

Alrosa CEO Pavel Maryinchev gave a remarkably upbeat assessment of the natural diamond market, telling the Times of India (TOI) that the industry is adapting well to US tariffs and that the threat from synthetic diamonds is diminishing.

Maryinchev (pictured) highlighted two major factors behind his optimism: steady global demand for jewelry and a decline in diamond production. “Inventories throughout the diamond pipeline are gradually normalizing, creating favorable conditions for price recovery,” he said.

Alrosa, Russia’s state-owned and sanctioned diamond miner, reported a 24 per cent drop in revenue in the first half of 2025 and has suspended production at several low-margin mines.

But Maryinchev remains confident. “Our expectations are that the high import tariffs will not have a long-lasting impact, and businesses will be able to adapt and minimize the effect,” he said.

He also pointed to a significant decline in wholesale prices for lab-grown diamonds, which fell nearly 40 per cent year-on-year in Q3 2025, reducing the competitive pressure on natural stones.

“Fears that synthetic substitutes might replace natural diamonds are becoming less likely to come true every year,” he told TOI.

He noted that, with no major new deposits discovered and existing mines producing less, supply constraints are increasingly stabilizing the market.

Global rough diamond production is expected to fall to 100 million carats in 2025, a 30-50% decline compared to six to eight years ago.

Maryinchev said the effect of US tariffs on demand was muted because luxury jewelry buyers tend to be less price-sensitive, and retailers can temporarily adjust markups.

“Diamond jewelry manufacturers may need time to adapt, but we expect India’s demand to recover once the first positive sales figures post-tariffs are achieved,” he said.

Diamond-Encrusted Timepieces: Haute Horology at Its Most Dazzling

Diamond-set watches from Cartier, Van Cleef & Arpels, Jaeger-LeCoultre and Graff represent the pinnacle of high jewellery watchmaking. With dials, cases and bracelets lavishly adorned with hundreds sometimes thousands of diamonds, these exceptional creations are true show-stoppers, blending technical mastery with extraordinary gem-setting artistry.

Both bold and refined, these spectacular ladies’ timepieces come from some of the world’s most prestigious watch and jewellery maisons. Almost entirely cloaked in diamonds, they are designed to command attention while maintaining an unmistakable sense of elegance.

Cartier’s iconic Baignoire watch traces its origins back to 1958, when it was first introduced as the Ovale cintre. Officially renamed in 1973, the modern mini jewellery version features a quartz movement and is set with hundreds of brilliant-cut diamonds, reaffirming its status as a timeless symbol of refined luxury.

Graff’s Tilda’s Bow diamond watch adds a distinctly feminine flourish. Accented by a graceful ribbon-inspired motif on one side, this statement piece features a pavé-set dial and a triple-row diamond bracelet, seamlessly combining softness with striking brilliance.

Jaeger-LeCoultre’s platinum 101 Secrets watch transcends both trends and seasons. Concealing a delicate mother-of-pearl dial, the piece is embellished with more than 1,000 diamonds meticulously set along the bracelet and case sides—an extraordinary demonstration of precision and craftsmanship.

Van Cleef & Arpels draws inspiration from the Art Deco “white period” of the 1930s with its À Cheval high jewellery watch. Reflecting the era’s preference for white gold paired with diamonds, the design pays homage to a defining moment in jewellery history, favouring refined monochrome elegance over the coloured gemstones of earlier decades.

Together, these diamond-encrusted watches showcase the seamless union of haute joaillerie and fine watchmaking—where time is measured not only in seconds, but in brilliance and craftsmanship.

Lab-Grown Diamonds Surge in Popularity, Both Globally and in Australia

Lab-grown diamonds are transforming the global jewellery market and Australia is no exception. What began as a value-driven alternative is now a major contributor to sales growth for leading jewellers around the world.

Signet Jewelers parent company of retail chains Kay Jewelers, Zales and Jared recently reported 6% same-store sales growth, largely fuelled by strong demand for fashion and bridal jewellery featuring lab-grown diamonds (LGDs). Today, LGDs represent around 40% of Signet’s bridal diamond sales, proving just how quickly consumer preferences are shifting.

This growth is driven by simple customer logic:
Larger stones. Greater brilliance. Lower cost.

Exceptional value at key gifting price points.

Retailers are seeing customers choose bigger, higher-quality stones because LGDs allow them to upgrade without increasing their budget a trend transforming both the bridal and fashion jewellery categories.

How Efforts to Control the Diamond Trade Are Hurting the Very Communities They Were Supposed to Protect

For more than two decades, global policies aimed at restricting the flow of diamonds from conflict zones most notably through the “blood diamond” narrative have reshaped the way diamonds are traded. These measures were intended to protect vulnerable communities in Africa from exploitation and violence. But today, the ripple effects of those same restrictions are being felt thousands of kilometres away, exposing the fragility of a supply chain that depends on the livelihoods of millions.

In India’s diamond capital of Surat, where an estimated 80% of the world’s diamonds are cut and polished, workers like Alpesh Bhai once saw diamonds as a pathway out of poverty. The industry offered stability, income, and, for the first time, the promise of private education for their children.

That progress has since been jeopardised.

A Perfect Storm of Restrictions and Sanctions

First, sanctions targeting Russian rough diamonds disrupted supply a supply which, for India, had been essential. Then came the imposition of 50% United States tariffs on polished diamonds, compounding the downturn.

The intention behind these measures from conflict-diamond controls in Africa to punitive trade tools against Russia has been to hold powerful actors accountable. Instead, the burden has fallen hardest on those with the least power in the chain: cutters, polishers, and their families.

Alpesh, once earning enough to support education for his two young daughters, saw his salary cut nearly in half before losing his job altogether. Private schooling quickly became unaffordable. He withdrew his children and moved them into a public school where learning opportunities are significantly limited.

“I’ve come back to where I started,” he said a sentiment now echoed across Surat.

The Human Cost Behind Supply Chain Pressure

Surat’s diamond sector employs over 600,000 people, many migrants from rural Gujarat who rely entirely on this trade. Layoffs, pay cuts, and reduced working hours have affected close to 400,000 workers.

Families are leaving the city. Children are dropping out of school. In the most tragic cases, mounting financial pressure has led to a rise in worker suicides.

Community leaders describe the situation as unprecedented. “The industry was always a ladder out of poverty,” one union representative explained. “Now that ladder is shaking for many, it’s disappearing.”

A Stark Reminder for the Diamond World

Conversations about responsible sourcing must include responsibility to all those in the value chain including cutters and polishers who transform rough diamonds into the beautiful stones valued globally.

Policies crafted to protect African workers from exploitation have, ironically, become a new form of harm both in Africa, where mining communities still struggle, and now in India, where workers are paying the price for geopolitical decisions far beyond their control.

As the global diamond market continues to evolve, one thing is clear:

Ensuring the ethical integrity of diamonds must not stop at the mine.
It must extend to every skilled hand that shapes them and every child whose future depends on this industry.

DCLA Transparent Certification and Shared Responsibility

Florentine Diamond: Austrian Government Weighs Legal Claim

Austria has convened a panel of experts to assess whether the government has a legitimate claim to the 137.27-carat Florentine Diamond, which resurfaced last month after vanishing for a century.

The newly established Florentine Commission will examine whether the gem belongs to the Austrian state or remains the private property of the Habsburg family.

The diamond, set in a brooch, was taken to Switzerland in 1918, along with other royal jewels, as the Austro-Hungarian Empire collapsed and the imperial family fled into exile. Empress Zita, widow of Emperor Karl I, later deposited the collection in a bank vault in Quebec, Canada – an act kept secret for generations.

Only two of her sons, Robert and Rodolphe, were told of its location, under instructions that the hiding place must remain undisclosed for 100 years after Karl’s death in 1922.

With the diamond’s whereabouts finally revealed, the central question is who owns it.

The First Austrian Republic, created in 1919 after the fall of the monarchy, claimed all Habsburg assets under the Habsburg Law. However, it remains unclear whether that law extended to property already removed from Austrian territory.

The Florentine Commission held its first meeting last Thursday (4 December) and is expected to issue its findings by fall 2026. In a statement the Austrian government described the jewels as having been “taken from the treasury” and “taken abroad”.

The Habsburg family’s position depends on whether the diamonds can be proven to have been classified as personal possessions before the monarchy was abolished. Conversely, Austria must show that the Florentine Diamond was officially part of the state regaliaâ€”and that the 1919 law applied to items no longer inside Austria.

The family has said it does not plan to sell the Florentine Diamond, but intends for it to go on public display at a museum in Canada.

Kim Kardashian Wears High-Value Diamonds to Paris Robbery Trial in Defiant Statement

Kim Kardashian has made a powerful return to wearing high-value diamonds, attending the Paris robbery trial this year adorned in a selection of exceptional jewellery pieces — a symbolic reclaiming of personal confidence after the traumatic 2016 incident in which approximately US$10 million worth of her jewellery was stolen.

In the latest episode of The Kardashians, Kardashian reflected on her decision to testify in Paris, supported by Kris Jenner and longtime friend Simone Harouche. The trio recounted the night of the robbery, describing the fear and uncertainty they faced as events unfolded.

Kardashian chose a vintage black John Galliano blazer dress for her court appearance, accessorised with a number of prestigious diamond pieces, including a Samer Halimeh diamond necklace valued at an estimated US$3 million, jewellery by Repossi and Briony Raymond, and a 22-carat Lorraine Schwartz diamond ring — re-acquired using insurance proceeds from the original theft.

Despite concerns raised by legal representatives regarding the presentation of such significant jewellery at the trial, Kardashian expressed a strong desire to maintain her sense of identity and autonomy. She noted that, for several years following the event, she avoided wearing diamonds entirely due to the trauma associated with the attack.

Kardashian stated that her choice to wear diamonds to the trial symbolises not only a personal milestone but a refusal to allow the actions of the perpetrators to dictate her life any longer. The reality star emphasised that reclaiming her confidence through jewellery was an intentional and empowering step forward.

Historic Fabergé Egg Encrusted with Diamonds Sets New World Record

A rare imperial Fabergé masterpiece lavishly adorned with platinum and 4,500 diamonds has achieved a remarkable £22.9 million at auction in London, establishing a new world record for any Fabergé artwork.

The famed Winter Egg was commissioned in 1913 by Emperor Nicholas II of Russia as an Easter gift for his mother, Dowager Empress Maria Feodorovna. Considered one of the most spectacular creations by the House of Fabergé, the piece showcases masterful artistry: a flawless rock crystal shell, intricately engraved to resemble winter frost, embellished with a delicate snowflake motif and shimmering diamonds.

Christie’s confirmed that the £22,895,000 sale price surpasses the previous Fabergé auction record by more than £13 million a benchmark also set by Christie’s in 2007 with the sale of the Rothschild Egg for £8.9 million. Remarkably, this is the third time the Winter Egg has broken the world record for a Fabergé creation.

“Today’s result reaffirms the enduring significance of this masterpiece, celebrating the rarity and brilliance of what is widely regarded as one of Fabergé’s finest creations,”
said Margo Oganesian, Christie’s Head of Fabergé & Russian Works of Art.

Only a limited number of Imperial Eggs remain in private ownership, making this sale a landmark moment for collectors and institutions worldwide.

A Tumultuous Century of Provenance

Following the fall of the Russian monarchy in 1917, the Winter Egg was moved to the Kremlin Armoury and later included in Soviet sales of royal treasures during the 1920s.

Over its journey through history:

Purchased by Wartski of London in the early 20th century for just £450

Sold privately in 1934 for £1,500

Considered lost between 1975–1994

Re-emerged at Christie’s in 1994, achieving a record 7,263,500 Swiss francs (£6.8 million)

Set a new record once more in 2002 at $9,579,000 (£7.1 million)

Today’s sale firmly cements its status as one of the most coveted objets d’art ever created.

Celebrating Excellence in Diamond Craftsmanship

With its extraordinary diamond detail and technical precision, the Winter Egg continues to define the pinnacle of artisanal luxury. Each stone carefully set into platinum reflects the superior craftsmanship that has made Fabergé synonymous with imperial elegance.

For DCLA, iconic pieces such as this highlight the enduring importance of diamond quality, authentication, and expert certification ensuring that history and value are preserved for future generations.
