G7 ban on Russian diamonds enters final phase as traceability rules bite

The final phase of the G7's sanctions regime against Russian diamonds came into force on 1 January 2026, requiring importers of natural polished diamonds within its scope to submit a Due Diligence Statement on Diamond Origin before the stones can enter G7 markets, in a bid to close remaining loopholes that had let Russian-origin diamonds reach Western consumers via third countries.

The rules build on sanctions first imposed after Russia's invasion of Ukraine, which banned direct imports of Russian rough and polished diamonds into the G7 and the European Union. Because much of the world's rough is cut and polished in countries such as India before being sold on, enforcing the ban required a system for tracing stones back to their country of origin rather than simply checking where they were last processed — the traceability mechanism that finally became mandatory at the start of 2026 after the EU had previously postponed it.

An opening for African producers

For African diamond-producing countries, which collectively account for around half of global output, the tightening of Russian sanctions represents a significant commercial opportunity. Alrosa, Russia's dominant miner, has effectively been locked out of the G7's lucrative jewellery markets, creating space for rivals in Botswana, Angola, Namibia, South Africa and elsewhere to capture market share that Russian stones once held.

Compliance costs for producers too

The new due diligence requirements are not free for African producers to comply with, however. Establishing credible export verification points inside producing countries has become a priority for regulators working with G7 governments, since buyers now need documentary assurance that non-Russian rough diamonds can be linked cleanly through to the polished stones sold at retail. Producers that cannot demonstrate robust chain-of-custody systems risk being treated with the same suspicion as sanctioned Russian supply, even though their diamonds are entirely legitimate.

A slow-moving reshaping of trade flows

The rules mark one of the most significant reorderings of the global diamond trade in decades, formalising a split between G7-compliant supply chains and everything else. For African governments already grappling with weak prices and falling revenue, gaining a durable edge over Russian competitors in G7 markets could offer some compensation — provided the compliance burden does not fall disproportionately on smaller, less well-resourced producers such as Sierra Leone's artisanal diggers or Lesotho's smaller mines.
