The Uncut Truth: The 3 Diamond Capitals Of The World And Their Existential Challenges In 2025
The global diamond trade is undergoing its most dramatic transformation in decades, and the traditional "diamond capitals" are fighting for their very existence. As of December 2025, the industry's power centers—historically defined by their unique roles in trading, cutting, and innovation—are being reshaped by geopolitical sanctions, disruptive US tariffs, and the unstoppable rise of lab-grown diamonds. This convergence of factors is challenging the dominance of the three cities that truly rule the world of diamonds: Antwerp, Surat, and Tel Aviv.
Forget the old narrative of glittering wealth; the current story of the diamond capitals is one of intense commercial pressure and a race to adapt. Understanding the modern diamond supply chain means recognizing the distinct, yet interconnected, roles played by these three geographical hubs, each facing unique, existential threats that are redefining the market for 2026 and beyond.
The Diamond Capitals: A Trio of Trade, Craft, and Innovation
The diamond industry is a complex global network, and no single city controls all aspects. Instead, three major metropolitan areas have historically specialized to become the undisputed capitals of their respective fields: rough trading, cutting/polishing, and high-value exchange.
- Antwerp, Belgium: The Rough Diamond Trading Hub (The Gateway)
- Surat, India: The Cutting and Polishing Center (The Factory)
- Tel Aviv (Ramat Gan), Israel: The High-Quality Exchange (The Innovator)
1. Antwerp, Belgium: The Rough Diamond Gateway Under Sanctions
Antwerp has long held the title of the undisputed "Diamond Capital of the World," primarily due to its dominance in the rough diamond trade. For centuries, the city’s historic Diamond Quarter, a small, highly secure area near the central train station, has served as the crucial entry point for most of the world's raw stones. Today, the city remains home to the Antwerp World Diamond Centre (AWDC), which oversees this massive operation.
The Geopolitical Threat: G7 Traceability Mandate
Antwerp’s dominance is currently being tested by the most significant geopolitical challenge in decades: the G7’s mandatory traceability mechanism, designed to restrict the circulation of Russian-origin diamonds.
- The Mandate: The G7 sanctions require all diamonds entering member countries to be fully traceable back to their country of origin.
- The Impact: This complex reform, initially targeted for full force by March 2025 for stones of 0.5 carats or larger, is aimed at cutting off the flow of Russian rough diamonds, a major source for Antwerp’s trade.
- The Latest Update (2025): As of late 2025, the full implementation of the traceability mandate has been postponed until 2026, a delay welcomed by the Antwerp diamond industry which has struggled with the technical and logistical complexity of the new system. This postponement offers a brief reprieve, but the city is already noted to be "losing ground" to other emerging hubs like Dubai.
Antwerp’s future hinges on its ability to quickly implement a robust, unified traceability system that satisfies G7 requirements while maintaining its reputation as the most efficient and trusted hub for rough diamond transactions.
2. Surat, India: The Cutting Powerhouse and the Lab-Grown Shift
While Antwerp trades the rough, Surat, a city in the Indian state of Gujarat, is where the magic of transformation happens. Surat is the unchallenged world capital of diamond cutting and polishing, a massive industrial cluster that processes an astonishing 90% of the world's natural diamonds. The industry employs over 1.5 million people, with approximately 500,000 of them working as master diamond cutters.
The Two-Front Battle: Tariffs and Technology
The Surat diamond industry, which is the largest cluster in India’s cut and polished diamond sector, is currently facing a dual challenge that is reshaping its labor force and business model.
- The US Tariff Shock: The threat of rising US tariffs on Indian gems and jewelry, with some proposals reaching 50%, has created significant turbulence. This has led to the industry cutting rough diamond purchases and operating with minimal inventories, causing the massive Surat Diamond Bourse—the world’s largest office building—to stand eerily quiet.
- The Lab-Grown Transition: The most significant long-term trend is the shift in production capacity. A substantial portion of Surat’s polishing units has transitioned to processing lab-grown diamonds, a trend expected to accelerate into 2026. This technological shift is a strategic hedge for the city, allowing it to maintain its cutting dominance even as the natural diamond market faces volatility and competition from synthetics.
Surat's future is no longer just about natural diamonds; it is rapidly becoming the global manufacturing capital for both natural and lab-created stones, a unique position that secures its place in the modern diamond supply chain.
3. Tel Aviv, Israel: The High-Value Exchange and Free-Trade Ambitions
The third major capital is the Israel Diamond Exchange (IDE) in Ramat Gan, near Tel Aviv. Israel has historically specialized in the trade of high-quality, larger, and innovative diamonds, acting as a crucial intermediary for polished stones. The IDE is one of the world's largest diamond exchanges, renowned for its expertise in high-tech cutting, advanced grading, and innovative industry practices.
The Existential Crisis and the Free-Trade Solution
The Tel Aviv diamond center is currently navigating a period of sharp decline, described by some as an "existential threat" due to global economic factors and trade disputes.
- Export Decline: Net exports of rough and polished diamonds from Israel fell by 23% year-on-year in the first eight months of 2025, a stark indicator of the market contraction.
- The Free-Trade Zone Proposal: In a bold move to reverse this trend, Israel's Finance Minister is pushing a proposition to make the country a diamond free-trade zone in the 2026 budget. This aims to eliminate tariffs and streamline customs processes, drastically reducing the cost of doing business and re-establishing the IDE as a globally competitive hub against rapidly emerging rivals like Dubai and even the new Surat Diamond Bourse.
- Digital Innovation: To secure its future, the IDE has also embraced digital commerce, including a high-profile partnership with eBay to boost the online role of its 3,500 members to new international shoppers.
Tel Aviv is therefore positioning itself as the agile, high-tech hub of the future, leveraging policy changes and digital platforms to maintain its relevance in the volatile global market.
The Entities Shaping the Diamond World in 2025
The fate of the three diamond capitals is inextricably linked to the actions of several powerful entities and disruptive technologies.
The Disruption of Lab-Grown Diamonds (LGDs)
The rise of Lab-Grown Diamonds is the single biggest technological disruption, impacting all three capitals. While LGDs are losing some of their appeal in certain segments, their market value is still projected to reach high double-digit billions of US dollars by 2025, forcing the natural diamond industry to consolidate and adapt.
- Surat: Has successfully integrated LGD polishing into its capacity, securing its manufacturing future.
- Antwerp & Tel Aviv: Must increasingly focus on marketing the rarity, heritage, and investment value of natural diamonds to differentiate their high-value trade.
Geopolitical Entities and Trade Challenges
The global trade landscape is being defined by a few key players and regulatory bodies:
- The G7: Their sanctions and traceability mandates are forcing a fundamental change in how rough diamonds are sourced and tracked, directly challenging Antwerp's traditional methods.
- The United States: The US remains the largest end-market for diamonds and its tariff policies (especially those impacting India and Israel) have immediate and profound effects on the midstream sector in Surat and Tel Aviv.
- De Beers and Alrosa: These major mining companies are experiencing a steady decline in rough supply since 2022, forcing the midstream (the cutters and traders in the three capitals) to operate with smaller inventories and higher financial pressure.
Conclusion: The Future is Fragmented, Not Centralized
The concept of the "3 diamond capitals of the world" remains valid, but their roles have become more specialized and contested than ever before. As of late 2025, Antwerp remains the gatekeeper for rough stones, Surat is the manufacturing engine for both natural and lab-grown diamonds, and Tel Aviv strives to be the high-value, free-trade hub.
Their collective future is defined by their ability to navigate the new world of mandated traceability, volatile tariffs, and the dual-market reality of natural versus synthetic diamonds. The next few years will not be about which city wins, but which city can best adapt to a fragmented, technologically advanced, and politically charged global diamond market.
