Global Diamond Market Showed Mixed Trends In March As The Middle East Conflict Escalates
How Scarcity In Large Stones and Geopolitical Shifting Are Redefining Luxury Value
The global diamond industry continues to navigate a multifaceted landscape as the second quarter approaches. While geopolitical shifts and evolving supply chains have introduced new pressures, the market remains defined by a clear divergence in demand—favoring high-carat rarity and strategic retail consolidation.
The escalation of conflict in the Middle East during February 2026 has reverberated through major trading hubs. Iranian missile strikes created temporary disruptions in Israel and Dubai, traditionally the heartbeat of the rough diamond trade. In response, rough tender houses have demonstrated remarkable agility, relocating sales to maintain liquidity.
Despite these logistical hurdles, the industry’s infrastructure remains resilient, though Indian manufacturers continue to monitor access to rough supply closely as tender locations shift.
The RapNet Diamond Index (RAPI™) for March underscores a market divided by size and scarcity. While the “big stone” luxury segment remains robust, smaller goods are facing a period of price correction.
The March performance metrics reveal a period of strategic recalibration across the diamond market, characterized by a clear correlation between stone size and price volatility. Smaller categories faced the most pronounced headwinds, with 0.50-carat stones undergoing a significant 3.5% adjustment and 0.30-carat goods softening by 1.1%. Mid-range 1-carat diamonds continued a gradual correction with a 1.7% decline, reflecting a broader trend of cautious buying in the commercial segment.
In contrast, the high-end 3-carat category demonstrated remarkable resilience, slipping only 0.5% to remain relatively stable—a testament to the enduring appeal and scarcity of larger, investment-grade stones amidst shifting global dynamics.
Conversely, 2-carat stones and above are witnessing a supply-side squeeze. Long fancy shapes are experiencing heightened desirability, and New York wholesalers report a steady flow of retail orders for high-end, investment-grade diamonds.
At the source, De Beers is signaling a more exclusive approach to the market. Following its March sight—where prices for 5-carat rough and above reportedly increased—the miner announced a reduction in its sightholder base. For the contract period beginning July 1, the list will shrink by 20–25 clients, ensuring that supply is concentrated among the most strategically aligned partners.
In the retail sector, Signet Jewelers closed its fiscal year with a strong performance, reporting $6.81 billion in sales (a 1.6% year-on-year increase). This financial health is paired with a strategic rebranding: the integration of the James Allen platform into Blue Nile. This move signals a renewed commitment to the natural diamond sector, positioning Blue Nile as a premier destination for consumers seeking authentic, timeless luxury.
While the reduction of US tariffs on Indian goods to 10% provides some relief, the industry remains vigilant. As we move further into 2026, the focus for global players will undoubtedly remain on securing high-quality rough and catering to the unwavering demand for the market’s most significant, large-scale stones.

DE BEERS GROUP Introduces Desert Diamonds Icons
Supported by the Diamond Industry’s Largest Marketing Budget In 15 Years, Desert Diamonds Icons Will Launch Ahead Of The End Of Year Holiday Season and Build On The Desert Diamonds Campaign’s Success In Driving Natural Diamond Desire
At the annual JCK Las Vegas Show – the largest jewellery event in the global calendar – De Beers Group today set out its view on the way forward for the natural diamond sector, calling on the trade to work together to capitalise on the early success of the Desert diamonds ‘beacon’ campaign with the introduction of Desert diamonds Icons.
The Desert diamonds beacon campaign launched in late 2025 and has already succeeded in shaping consumer demand for both natural diamonds in general and coloured diamonds in particular, with natural diamond sales at US independents increasing 4% in Q4 2025 and 9% in Q1 2026, while those in the K to Z colour range have seen even stronger growth, up 15% in Q4 2025 and 19% in Q1 2026.
Following the launch of Desert diamonds Bridal earlier this year, Desert diamonds Icons will focus on bringing a sense of newness and individuality to four iconic jewellery design classics – stud earrings, the eternity band, the tennis bracelet and the halo pendant – which between them comprise 70% of diamond jewellery acquisitions. Launching in September, the campaign will include training and marketing support for all retailers.
During a keynote presentation, De Beers Group executives stated that while demand has performed well for larger natural diamonds and this has supported stable retail sales value for natural diamond jewellery, it is critical for industry participants to work together on the campaign to drive demand across the natural diamond category as a whole.
With the campaign benefitting from the diamond industry’s biggest natural diamond marketing budget in 15 years, Desert diamonds is expected to deliver enhanced retail impact in 2026, based on a range of positive data points from its initial run. Growth in natural diamond desirability, online searches for natural diamonds, and increased coloured natural diamond sales across independent jewellers all highlight that the momentum behind the campaign is building. Noting that the 2026 campaign run will also benefit from a geo-targeting approach that directs consumers to specific retailers carrying Desert diamonds, De Beers executives encouraged the entire trade to support the fast-growing trend by stocking Desert diamonds Icons products and by signing up to Promoboxx to access marketing materials and participate in geo-targeting.

The presentation also included a summary of key consumer and industry insights published today in The Diamond Report, highlighting how commercial dynamics are evolving at pace for US jewellery retailers as the synthetic lab-grown diamond sector matures while consumer interest in natural diamonds grows.
Speaking at the presentation, Al Cook, CEO of De Beers Group, said:

“Consumer desire for natural diamonds is strong – but we need to work together as an industry in support of Desert diamonds to unlock the full value of the opportunity. The results from the campaign’s initial run demonstrate how it is already stimulating demand, and with Desert diamonds Icons we are doubling down at a critical moment.”
“The jewellery retail landscape is evolving at pace. With the sustained falls in price of synthetic lab-grown diamonds, and large falls in demand for larger synthetic lab-grown diamonds, there may be challenges ahead for retailers who focus on synthetic lab-grown diamonds.”
“However, with challenge comes opportunity, and the growing success of the Desert diamonds campaign is evident. As we head into the campaign’s second year, with the industry supported by the largest category marketing budget in 15 years, the natural way forward is clear to see.”
De Beers Group also reported in its presentation how collaboration continues deliver progress in other areas, with GIA’s purchase of an equity share in Tracr supporting the platform’s path to independence and providing the potential for it to scale faster across the sector.
Meanwhile, the Natural Diamond Council has put in place a compelling new strategy on the back of its growing budget, as more diamond producing countries and trade bodies have provided funding, and will introduce a new natural diamond trust mark to support consumer confidence through visible differentiation between natural diamonds and synthetic lab-grown diamonds.
