The Diamond Industry’s Future: 7 Trends You Can’t Ignore in 2026
Mumbai—Just two months into 2026, and the world feels like it’s spinning faster than ever. Global political and economic turbulence has reached a fever pitch, leaving the diamond industry—already recovering from a prolonged slump—in a precarious position. With sudden shifts threatening years of careful planning, what does the rest of 2026 hold for this fragile sector? How will it navigate these uncertain waters, and what trends should businesses keep a close eye on?
National Jeweler sat down with top diamantaires, trade leaders, and industry analysts in India to uncover their insights. Combining their expertise with the latest data, we’ve identified seven critical trends that could shape the diamond industry’s future. But here’s where it gets controversial... some of these trends might challenge everything you thought you knew about the market.
1. The Uneven Recovery: A Tale of Two Markets
2025 saw diamond demand rise in the U.S. and India, with positive signals from other markets. But this is the part most people miss: the recovery isn’t uniform. While high-end retail sparkles, the midstream segment is a mixed bag. Russell Mehta of Rosy Blue India notes that larger diamonds (above 2-3 carats) are stable, and smaller stones (below 0.18 carats) are showing signs of improvement. However, the mid-tier market (20 points to 2 carats) remains ‘stressed,’ thanks to China’s subdued demand and the rise of synthetic diamonds in the U.S. Is this the new normal, or just a temporary blip?
2. Tariffs, Sanctions, and Trade Deals: The Never-Ending Saga
Tariffs and trade negotiations dominated 2025, with the India-U.S. deal offering brief relief. But tariffs are back, hovering at 10% (possibly rising to 15%). While this eases the burden on importers, the fate of loose natural diamonds remains unclear. And this is the part most people miss: smaller trade deals with the UK, EU, Oman, and Australia are quietly providing much-needed boosts. Are these deals enough to offset the tariff turmoil?
3. Supply Side Equilibrium: A Delicate Dance
A balance between supply and demand is returning, but not because of rising demand—it’s due to tighter supply control. Industry analyst Pranay Narvekar predicts equilibrium by mid-2026, with rough production hovering around 100 million carats. Major miners have slashed production, and smaller mines are shutting down or shifting to lab-grown diamonds. But here’s where it gets controversial: is this controlled supply sustainable, or will it backfire in the long run?**
4. The Natural Diamond Comeback: A Marketing Blitz
The Luanda Accord marked a turning point, with mining countries and midstream organizations joining forces to promote natural diamonds. The Natural Diamond Council is set to unleash a global marketing campaign in 2026. In India, sustained campaigns by De Beers, Titan, and GJEPC are already paying off, with diamond jewelry sales poised to double by 2030. But is this enough to compete with the allure of lab-grown diamonds?
5. Governments Take Center Stage
Governments’ role in the diamond industry is growing, with a potential game-changer on the horizon: a coalition of diamond-mining countries could become majority stakeholders in De Beers. Anglo American’s CEO confirmed advanced discussions, with Botswana playing a crucial role. Meanwhile, India’s leadership of the Kimberley Process aims to revitalize its chain of custody mechanism. But here’s where it gets controversial: can governments truly balance industry growth with ethical oversight?**
6. Lab-Grown Diamonds: Has the Bubble Burst?
Lab-grown diamonds, once a market disruptor, may have reached their peak. Wholesale prices have plummeted, and unit sales declined in January 2026. Retailers are struggling to maintain profits, and industry insiders predict a shift toward large chains. And this is the part most people miss: as margins shrink, could lab-grown diamonds lose their luster entirely?**
7. AI’s Quiet Revolution
AI is transforming the diamond industry, but not where you’d expect. Vinit Jogani of Diatech.AI highlights its impact on business planning, pricing intelligence, and inventory optimization. While manufacturing and mining are slower to adopt, jewelry product development and retail marketing are already feeling the effects. But here’s where it gets controversial: will AI democratize the industry, or widen the gap between big players and small businesses?**
Final Thoughts: What’s Next?
As 2026 unfolds, the diamond industry stands at a crossroads. From uneven recoveries to AI disruptions, these trends raise more questions than answers. What do you think? Are these trends a recipe for success, or a warning sign of deeper challenges? Share your thoughts in the comments—let’s spark a debate!
