In December 2023, the European Union adopted its twelfth package of sanctions against Russia, which included, for the first time, a comprehensive prohibition on the import of Russian-origin diamonds into EU member states. The measures — coordinated with the broader G7 framework announced earlier that year — represent the most significant regulatory intervention in the global diamond trade since the Kimberley Process was established in 2003. Their implications extend well beyond European borders, touching the world's principal cutting and trading centres and accelerating a structural shift in how the industry documents and verifies gemstone provenance.

Background and political context

Following Russia's full-scale invasion of Ukraine in February 2022, Western governments imposed successive rounds of economic sanctions targeting Russian energy, finance, and luxury goods. Diamonds were initially excluded, in part because of the complexity of tracing rough stones through multi-jurisdictional supply chains and in part because of lobbying by trade interests in Antwerp and Mumbai. Russia's state-owned mining company, ALROSA, is the world's largest producer of rough diamonds by volume, accounting for roughly 30 per cent of global rough supply by carat weight in the years preceding the sanctions. Restricting access to that supply without a credible traceability mechanism risked either market disruption or straightforward circumvention through third-country re-export.

The G7 nations — Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States — announced in principle their intention to restrict Russian diamond imports at their Hiroshima summit in May 2023. The EU's 12th package, adopted on 18 December 2023, gave that commitment legal force within the bloc, with phased implementation timelines designed to allow the trade time to adapt.

Scope of the prohibition

The sanctions as adopted cover:

• Rough diamonds of Russian origin, prohibited from direct import into the EU from 1 January 2024.
• Polished diamonds of Russian origin, including those processed in third countries, subject to a phased ban: stones of one carat and above were prohibited from 1 March 2024, with the threshold lowered to 0.5 carats from 1 September 2024.
• Diamond jewellery incorporating Russian-origin stones, subject to parallel restrictions aligned with the polished-diamond timeline.

The phased approach acknowledged the practical reality that a large proportion of Russian rough is cut and polished in India — principally in Surat — before entering European or American markets. A blanket immediate ban on polished goods would have required instant traceability infrastructure that did not yet exist at scale.

The G7 traceability mechanism

The central technical challenge of the sanctions regime is distinguishing Russian-origin diamonds from those mined elsewhere — a task that is analytically difficult because diamonds from different sources can be physically indistinguishable without sophisticated spectroscopic testing. The G7 agreed to establish a verification and traceability mechanism, with Antwerp's World Diamond Council and the Antwerp World Diamond Centre (AWDC) designated as a hub for implementing import controls.

Under the mechanism, rough diamonds above the relevant weight thresholds must be accompanied by documentation attesting to their non-Russian origin, and physical verification — including, where applicable, spectroscopic analysis — is required at the point of import. The G7 has worked with industry bodies to develop a blockchain-based tracking system that records a stone's chain of custody from mine to market. Several technology providers, including Tracr (developed with De Beers involvement) and Everledger, offer platforms capable of creating immutable digital records linked to individual stones via laser inscription of unique identifiers.

The laser inscription of a stone's origin certificate number on the girdle — already standard practice for graded diamonds — becomes, under this framework, not merely a consumer-facing quality marker but a compliance instrument. Laboratories including the Gemological Institute of America (GIA) and the International Gemological Institute (IGI) have adapted their reporting to accommodate origin documentation requirements.

Impact on Antwerp

Antwerp has historically been the world's foremost rough diamond trading hub, and Russia was among its most significant suppliers. Prior to the sanctions, ALROSA sold a substantial portion of its production through Antwerp-based sightholders and on the open market. The AWDC estimated that Russian rough accounted for approximately 25 per cent of the rough diamonds traded through Antwerp in the years before 2022.

The sanctions have materially altered Antwerp's trade flows. Some Russian rough has been redirected to Dubai and other centres not bound by G7 restrictions. At the same time, Antwerp's designation as the primary G7 verification hub has reinforced its administrative centrality to the compliant trade, even as its raw volume has declined. The city's diamond district has invested in verification infrastructure and trained customs officials in the new protocols, positioning Antwerp as the compliance gateway for diamonds entering G7 markets.

Enforcement and circumvention risks

Sanctions regimes are only as effective as their enforcement, and the diamond trade presents particular challenges. Rough diamonds are small, high in value relative to weight, and easily transported. The absence of a universal, scientifically validated origin-testing protocol — analogous to, say, isotope analysis for coloured gemstones — means that documentary fraud remains a meaningful risk. A Russian rough stone polished in India and accompanied by falsified Indian-origin paperwork is difficult to detect without either physical spectroscopic testing of the finished stone or an unbroken chain of digital custody records from the mine.

The G7 mechanism addresses this partly through spectroscopic screening at Antwerp, but the capacity to screen every stone above the threshold weight is limited. Industry observers have noted that the effectiveness of the sanctions will depend heavily on the willingness of third-country cutting centres — particularly India — to enforce origin documentation requirements on their own exports, which in turn depends on diplomatic and commercial incentives that are not uniformly aligned.

Implications for the broader diamond market

The sanctions have coincided with — and in some respects accelerated — a period of structural adjustment in the diamond market. The rise of laboratory-grown diamonds has already compressed margins on smaller polished stones, and the removal of a significant volume of Russian rough from compliant supply chains has contributed to price volatility in certain size and quality categories. Some market participants have argued that the supply restriction has provided temporary price support for natural diamonds in the affected categories; others contend that the redirection of Russian goods to non-G7 markets has limited the sanctions' economic impact on ALROSA.

For jewellers and retailers operating in G7 jurisdictions, the sanctions have created new due-diligence obligations. Sourcing documentation must now address not only the ethical provenance questions associated with the Kimberley Process but also the geopolitical origin question introduced by the Russian sanctions. Auction houses, luxury retailers, and independent jewellers are reviewing their supply chains and, in some cases, requiring suppliers to provide G7-compliant origin certification as a contractual condition.

Relationship to the Kimberley Process

The Kimberley Process Certification Scheme (KPCS), established in 2003 to curtail the trade in conflict diamonds, operates on a government-to-government basis and defines conflict diamonds narrowly as rough stones used to finance rebel movements against legitimate governments. Russia, as a participating country, remains within the KPCS framework; the EU sanctions therefore operate entirely outside and parallel to the Kimberley Process. This distinction is significant: a diamond can be fully Kimberley-compliant and simultaneously prohibited under the EU sanctions regime. The coexistence of two parallel certification requirements has added administrative complexity for traders and has renewed calls for a broader reform of the Kimberley Process to address state-level conduct.

Outlook

The EU sanctions on Russian diamonds are, as of mid-2025, still in their early implementation phase. Their long-term effectiveness will be determined by the robustness of the traceability infrastructure, the degree of third-country cooperation, and the political durability of the G7 consensus. What is already clear is that they have permanently altered the terms on which provenance documentation is required in the diamond trade, and have given significant commercial impetus to technologies — blockchain custody records, spectroscopic origin testing, laser inscription — that were previously regarded as aspirational rather than operationally necessary.
