The Diamond Industry's Uncertain Future: 7 Trends to Watch in 2026 and Beyond
The diamond industry is on a rollercoaster ride, and 2026 is shaping up to be a year of high stakes and intriguing developments. With just two months gone, the industry finds itself in a delicate recovery phase amidst global political and economic turbulence. But what does the rest of the year hold? Here's a deep dive into the trends that could define the industry's path.
1. Uneven Recovery: A Tale of Two Markets
The diamond industry's recovery in 2025 was a mixed bag. While the top two markets, the United States and India, saw a surge in demand, China remained an exception. Manufacturers believe China's decline may have bottomed out, but the recovery is far from uniform. The high-end retail market shines, but the midstream level tells a different story.
Russell Mehta, a prominent industry figure, highlights the stability in demand for larger diamonds and the firming up of prices. However, the mid-tier segment, ranging from 20 points to 2 carats, remains stressed, with China's subdued demand and the U.S. market's shift towards synthetic diamonds.
2. Trade Turbulence: Tariffs, Sanctions, and Deals
The trade landscape is a dynamic one, with tariffs and trade deals taking center stage. The India-U.S. negotiations dominated the discourse in 2025, with a potential settlement offering relief to the industry. But the situation is fluid, and tariffs are back, impacting importers and potentially loose diamonds and gemstones.
But here's where it gets controversial: Will the tariffs be a temporary setback or a long-term challenge? And how will the industry adapt to the ever-changing trade environment?
3. Supply Side Balance: Miners and Mid-Stream in Focus
A stable supply-demand balance is emerging, but it's not due to rising demand. Industry analyst Pranay Narvekar attributes this to tightly controlled supply, with rough production significantly lower than past peaks. The midstream sector has also restructured, reducing overall capacity.
4. Marketing Blitz: Natural Diamonds in the Spotlight
The Luanda Accord marked a turning point, with governments of mining countries and midstream organizations joining forces with the Natural Diamond Council to promote natural diamonds. This collaboration is expected to result in a marketing blitz in key markets during the major selling seasons of 2026.
India, already witnessing the success of marketing campaigns by industry leaders, is set to see a significant boost in diamond jewelry sales, with demand projected to almost double by 2030.
5. Government Influence: A New Era?
The role of governments in the diamond industry is evolving. With Anglo American's potential sale of De Beers, a coalition of diamond mining countries could emerge as significant stakeholders. This development could reshape the industry's dynamics, especially on the supply side.
India's leadership in the Kimberley Process this year aims to create a new awareness, highlighting the mechanism's role in fostering legitimate pipelines, socio-economic development, and democratic governance in diamond-producing countries.
6. Lab-Grown Diamonds: Have They Peaked?
The rise of lab-grown diamonds as a competitive force to natural diamonds may have reached its zenith. Wholesale prices have declined, and retailers face the challenge of maintaining profits. Industry experts predict a shift towards larger chains as retailers seek to sell higher volumes to sustain margins.
A recent report suggests that the lab-grown diamond market is transitioning to a more mature phase, indicating a potential peak in sales.
7. AI Revolution: Transforming the Industry's Backbone
AI technology is making its mark, with diamantaires experiencing its impact in business planning and trading. AI-driven pricing, inventory optimization, and analytics are now daily tools. The future promises even more, with Generative AI potentially influencing manufacturing planning.
However, the adoption of AI varies across the industry, with upstream segments like mining and rough manufacturing having longer implementation cycles.
And this is the part most people miss: How will the industry adapt to the increasing role of AI, and what ethical considerations will arise as AI becomes integral to diamond production and sales?
As the diamond industry navigates these trends, the coming months will be crucial. The industry's resilience and adaptability will be tested, and the decisions made now could shape its future for years to come. What do you think the industry should prioritize in these uncertain times? Share your thoughts and let's spark a discussion on the future of diamonds.
