Singapore to Host 41st World Diamond Congress in July 2026

Before you spend a single dollar on a diamond in 2026, something fundamental has already changed: as of January 1, the European Union now requires Kimberley Process certificates to clearly state the country of mining origin, a traceability mandate that has quietly redrawn what "certified" actually means at the jewelry counter. The diamond industry will gather to reckon with exactly that shift, and several others, when the 41st World Diamond Congress convenes July 12-15 at the Sands Expo and Convention Centre in Singapore.

Organized jointly by the World Federation of Diamond Bourses (WFDB) and the International Diamond Manufacturers Association (IDMA), the same partnership that has convened the biennial summit since the first Congress in Antwerp in 1947, the 41st edition carries unusual weight. Fabio Cascapera, President of the Diamond Exchange of Singapore and Chair of the WDC 2026 Organising Committee, has called it a "Diamond Davos": a summit where government representatives, miners, manufacturers, retailers, and certification bodies from the ASEAN region and beyond will negotiate the terms of a $100 billion global market under acute structural pressure. "We are excited to hold this pivotal industry gathering once again in Singapore," Cascapera has said. Former DES President Suresh Hathiramani also sits on the Organising Committee, alongside WFDB President Yoram Dvash, who was reelected at the 40th Congress in Ramat Gan, Israel in March 2023.

Singapore last hosted the World Diamond Congress in 1988, when the city-state held the 24th edition. In the 38 years since, Asia has become the engine of global luxury demand, and that transformation is the implicit argument for returning. The WFDB's 27 member bourses will be represented at the Sands Expo alongside voices from Indonesia, Malaysia, the Philippines, Thailand, and Vietnam, markets that Cascapera and Hathiramani have specifically identified as fast-growing luxury frontiers within what they describe as one of the world's fastest-growing trade blocs.

Five debates will dominate the agenda in Singapore, and each carries direct consequences for what consumers should expect, and demand, at the jewelry counter.

The most immediately consequential is origin disclosure. The EU's January 2026 traceability deadline lands directly on the Congress agenda, and the numbers behind it are stark: of the roughly $15.5 billion in global rough diamond supply forecast for 2025, only an estimated $12.5 billion was available to Western buyers net of G7 and EU sanctions on ALROSA, Russia's dominant diamond mining giant. Whether those sanctions ease, tighten, or hold, and how retailers adapt their provenance language in response, will be the most politically charged conversation at the Sands Expo.

Running closely behind is the future of De Beers. Anglo American PLC's potential sale of the world's largest diamond marketer has created the most significant structural uncertainty in supply in a generation. At the 40th Congress in Ramat Gan, sessions headlined by Botswana President Duma Boko, Angolan Minister of Mineral Resources Diamantino Azevedo, Botswana Minister of Minerals and Energy Bogolo Kenewendo, and De Beers CEO Al Cook made unmistakably clear how central African producers are to the supply chain. That dedicated Africa panel carries directly into Singapore, where the question is no longer just who mines diamonds but who controls the terms of trade.

The third pressure is lab-grown diamonds. Accelerating penetration, particularly in the US market, has compressed natural diamond valuations at retail, and the Congress's demand-creation panel will attempt to define the natural diamond not merely as a product category but as a provenance narrative worth paying for. What emerges from those sessions will shape how jewelers pitch and price natural stones through the next retail cycle.

Fourth is the ASEAN opportunity. Indonesia, Malaysia, the Philippines, Thailand, and Vietnam collectively represent an emerging demand story beyond established powerhouses China and India. The Congress's Asian consumer markets panel will translate those growth signals into retail strategy, potentially redirecting supply-chain investment and brand positioning for years to come.

Fifth, and least discussed publicly, is the generational handover. A dedicated succession panel confronts the structural reality that much of the diamond trade's institutional knowledge and relationship capital is concentrated in a generation approaching retirement. How that knowledge transfers, and whether next-generation leadership embraces tightening traceability and sustainability standards, will determine the industry's long-term credibility with younger buyers who are already asking harder questions.

What Singapore produces in July may prove as durable as some of the Congress's most landmark decisions: the World Diamond Council, created at the 2000 Antwerp Congress specifically to combat conflict diamonds, and the International Diamond Council, which traces its global grading-standards mandate to the 18th Congress in Amsterdam in 1975, both reshaped the trade for decades. Consumers can get ahead of whatever the 41st Congress decides by asking specific questions at the counter today.

When speaking with any jeweler before purchasing a diamond, ask to see the Kimberley Process certificate and confirm it specifically names the country of mining origin, not just a trade region or continent. Ask whether the stone's provenance is traceable beyond the KP certificate, through a blockchain record or a gemological report naming the mine of origin. Ask explicitly whether the diamond is natural or lab-grown, and press for how that distinction is reflected in the asking price. Ask which third-party laboratory certified the stone, whether GIA, IGI, or HRD, and request the corresponding grading report by number so you can verify it independently. And ask whether the retailer's supply chain has been audited against any ethical sourcing standard beyond the Kimberley Process itself, since the Process sets a minimum threshold, not a ceiling.

The jeweler who can answer all five questions without hesitation is the one worth trusting with a significant purchase. The Congress in Singapore this July will be deciding, among much else, how many jewelers can.
