Diamond Mining Origin and EU Rules: Retailer Guide

A natural diamond can be mined in one country, sorted in another, polished elsewhere, graded by a laboratory and sold through Antwerp before reaching a European jewellery store.

Each location describes a different part of the supply chain.

Diamond mining origin means the country where the rough natural diamond was extracted from the earth. It is not automatically the country where the diamond was polished, graded, traded or sold.

This distinction matters under current European Union rules because restrictions can continue to apply to Russian-origin diamonds even when they have been processed in another country.

Quick Answer: What Is Diamond Mining Origin?

Diamond mining origin is the country where a natural rough diamond was extracted.

It is different from:

• The country where the rough was sorted.
• The country where it was cut and polished.
• The location of the grading laboratory.
• The trading centre through which it was purchased.
• The country where it was sold to the final customer.

Under the current EU sanctions framework, simply polishing a Russian-origin diamond in a third country does not automatically remove its Russian origin for sanctions purposes. For relevant polished natural diamonds under CN code 7102 39 00, the latest EU amendment requires traceability evidence, including a due-diligence statement, from 24 April 2026.

The Five Locations in a Diamond’s Supply Chain

A diamond may therefore be accurately described as:

• Mined in Botswana.
• Polished in India.
• Graded in the United States.
• Sourced through Antwerp.
• Sold by a jeweller in France.

Only the first statement identifies the mining country.

Mining Origin Is Not the Same as Polishing Country

“Polished in India” means that the cutting and polishing work occurred in India. It does not establish where the rough diamond was mined.

Likewise:

• “Antwerp sourced” identifies a trading or sourcing route.
• “GIA graded” identifies a grading organisation or report.
• “Sold in Paris” identifies the retail market.
• “Belgian supplied” identifies a supplier location.

None of those descriptions independently proves the mining country.

A Russian-origin rough diamond does not automatically become Indian-origin because it was polished in India. Processing location and mining origin answer different questions.

Why Mining Origin Matters Under EU Rules

Article 3p of Council Regulation (EU) No 833/2014 contains restrictions concerning diamonds originating in or exported from Russia.

The framework was introduced in stages:

The latest EU amendment requires importers to provide evidence of the country of origin of diamonds—or diamond inputs used to process a product in a third country—when the relevant Article 3p rules apply.

The exact treatment of a shipment depends on factors including:

• CN customs classification.
• Whether the goods are rough, polished, synthetic or incorporated into another product.
• Individual diamond weight.
• Mining origin.
• Processing route.
• Import date.
• Previous verification.
• Available exemptions or grandfathering provisions.
• The importer’s role and Member State.

Do not use the 0.5-carat threshold as a universal statement that every smaller Russian-origin diamond is permitted. Different paragraphs, classifications and restrictions can apply.

Why Third-Country Processing Does Not Erase Origin

The EU framework includes products processed outside Russia when they consist of relevant diamonds originating in or exported from Russia.

For example:

1. A rough diamond is mined in Russia.
2. It is exported to another country.
3. It is cut and polished there.
4. The polished diamond is offered for import into the EU.

The polishing location does not automatically replace the Russian mining origin for sanctions analysis.

This is why “polished in India” is not sufficient evidence of non-Russian mining origin. The importer needs records supporting the relevant origin conclusion.

What Changed on 24 April 2026?

Council Regulation (EU) 2026/506 amended Article 3p so that, for relevant products under CN 7102 39 00, mandatory traceability evidence applies from 24 April 2026.

That evidence includes a due-diligence statement confirming that the diamonds were not mined, processed or produced in Russia.

The due-diligence statement is not simply a marketing certificate. It is an importer declaration that should be supported by reasonable verification and appropriate records.

Older Commission and AWDC material may still show 1 January 2026 because those pages were prepared before the later amendment. Businesses should rely on the latest binding legislation and current instructions from their competent authority.

For the detailed declaration process, use the separate EU Diamond Due Diligence Statement guide.

Who Is Responsible?

The formal origin-evidence requirement in Article 3p applies at importation and directly concerns the importer.

However, other businesses in the supply chain should not assume that they have no responsibilities.

Importers should

• Determine the correct CN classification.
• Confirm whether the shipment is in scope.
• Obtain the required origin evidence.
• Complete required declarations.
• Preserve customs and supplier records.
• Follow instructions from the relevant authority.

Wholesalers and suppliers should

• Preserve links between imported goods and supporting records.
• Avoid mixing documented goods with unidentified stock without controls.
• Provide accurate declarations to customers.
• Distinguish mining origin from polishing and trading locations.

Retailers should

• Ask what evidence supports origin claims.
• Keep supplier invoices and declarations connected to inventory.
• Avoid making customer claims that exceed the available records.
• Separate current purchases, legacy stock and customer buybacks when their documentation differs.
• Escalate uncertain cases to the supplier or a compliance adviser.

Retailers who import directly into the EU take on the importer role for those transactions.

For a broader process, use the EU diamond sanctions compliance checklist.

What Is the Kimberley Process?

The Kimberley Process Certification Scheme is an international system governing trade in rough diamonds.

The Kimberley Process defines conflict diamonds narrowly as rough diamonds used by rebel movements or their allies to finance conflict aimed at undermining legitimate governments. Participating countries implement import and export controls, and international shipments of rough diamonds must be accompanied by validated Kimberley Process certificates.

The EU implements the scheme through Council Regulation (EC) No 2368/2002.

Important limitations include:

• The scheme primarily regulates rough-diamond shipments.
• It is not a standard grading report.
• It does not grade colour, clarity, cut or carat.
• It does not automatically provide a complete mine-to-customer history.
• Its official conflict-diamond definition is narrower than every possible human-rights, environmental or responsible-sourcing concern.

Because of that narrower scope, Kimberley Process compliance should not, by itself, be marketed as proof that a diamond satisfies every ethical, environmental or traceability claim. The Kimberley Process explains its scope here.

Kimberley Process Certificates and EU Origin Rules

The Kimberley Process and EU Russian-diamond restrictions are connected, but they are not identical systems.

For relevant rough-diamond imports, the current Article 3p framework requires the Kimberley Process certificate to clearly state the country—or countries—of mining origin.

From 1 March 2025, an unidentified “mixed origin” description is not sufficient for the affected rough imports unless another applicable legal treatment, such as qualifying prior G7 or grandfathered certification, applies.

The dedicated Mixed-Origin Kimberley Process Certificate guide should own the complete mixed-parcel procedure.

What Is G7 Diamond Verification?

G7 verification is part of the additional framework developed to support restrictions on Russian diamonds.

According to AWDC, qualifying natural rough diamonds verified through the designated Antwerp import node receive a G7 reference. That reference can help preserve the connection between verified rough and polished diamonds produced from it.

A G7 reference is not:

• A colour or clarity grade.
• A standard grading report.
• A valuation.
• A guarantee of exact mine-level traceability.
• A certificate issued for every polished diamond.

Detailed comparisons between G7 and grandfathered references belong on the G7 Certificate vs GF Number guide.

What Does a Due-Diligence Statement Prove?

A Due Diligence Statement records the importer’s declaration concerning the relevant diamond origin and the verification steps taken.

It should be supported by evidence such as:

• Kimberley Process documentation where applicable.
• G7 or GF references where applicable.
• Supplier origin declarations.
• Invoices.
• Packing lists.
• Shipping records.
• Customs records.
• Traceability-system extracts.
• Internal inventory references.

It should not be described as an independent laboratory guarantee of exact mining origin.

A statement that goods are “non-Russian origin” also does not necessarily identify one exact mining country. The records must be checked to determine how specific the supported origin information actually is.

Grading Reports Are Not Automatically Origin Reports

A standard diamond grading report normally records gemological information such as:

• Whether the material is natural or laboratory-grown.
• Shape and cutting style.
• Measurements.
• Carat weight.
• Colour.
• Clarity.
• Cut information where applicable.
• Polish.
• Symmetry.
• Fluorescence.
• Identifying characteristics.

That information helps identify and evaluate the diamond, but it does not automatically provide a complete mining-origin history.

Some laboratories and producers offer separate origin programmes. Those services use different processes and should not be confused with an ordinary grading report.

Use the Diamond Origin Report Guide for the full distinction between grading, origin and provenance documentation.

What Documents Should a Retailer Request?

The appropriate evidence depends on the goods and the transaction, but a retailer can ask the supplier for:

A verbal statement such as “our supplier is trusted” is not equivalent to an organised documentation file.

A Practical Diamond Record

Where applicable, keep the following connected to the diamond, parcel or stock reference:

• Internal stock number.
• Supplier name.
• Supplier invoice.
• Purchase date.
• Carat weight and measurements.
• Grading-report number.
• Mining-origin information actually supplied.
• Polishing country, if known.
• Supplier declaration.
• Relevant G7 or GF reference.
• Customs or shipment reference.
• Due-diligence documentation.
• Customer invoice after sale.
• Notes identifying any missing information.

Records should be retained according to applicable law, company policy and advice from the relevant authority. This article should not invent one universal retention period for every business and Member State.

Avoiding Aggregation Problems

Aggregation occurs when diamonds from different sources or documentation histories are combined.

For example, a parcel may contain:

• Diamonds from several known mining countries.
• Verified and unverified goods.
• Current and legacy stock.
• Newly imported and customer-buyback diamonds.

Once goods are mixed without preserving their identities, it may become harder to support an origin statement.

The full control process belongs on the Diamond Aggregation EU Rules guide.

How to Describe Diamond Origin Accurately

Use language that matches the available evidence.

If only the trading route is known

Use:

> “This natural diamond was sourced through Antwerp.”

Do not use:

> “This diamond was mined in Belgium.”

If only the polishing country is known

Use:

> “This diamond was cut and polished in India.”

Do not use:

> “This is an Indian-origin diamond.”

If the mining country is documented

Use:

> “Available supplier documentation identifies Botswana as the country of mining origin.”

This wording is more precise than implying that the retailer independently verified the exact mine.

If only non-Russian status is supported

Use:

> “Supplier and import documentation supports the declared non-Russian origin.”

Do not name a specific mining country without evidence.

If the history is incomplete

Use:

> “The grading and commercial records are available, but the complete mining-origin history is not documented.”

Do not guess.

“Ethical,” “Responsible” and “Fully Traceable” Claims

These descriptions require more than general supplier reassurance.

Before using them, establish:

• What the term means under the company’s written policy.
• Which stages of the supply chain are documented.
• Whether the evidence identifies a country, producer or mine.
• Which environmental and human-rights criteria were assessed.
• Whether the claim applies to every item or only selected stock.
• Whether records can substantiate the claim if challenged.

A Kimberley Process certificate does not automatically prove every broad ethical or environmental statement. Likewise, a non-Russian declaration does not automatically establish complete mine-to-market traceability.

Use narrower language when the evidence is narrower.

Retailer Origin-Documentation Process

Step 1: Identify the product

Record whether the goods are:

• Rough or polished.
• Loose or incorporated into jewellery.
• Natural or laboratory-grown.
• Industrial or non-industrial.
• Individual stones or a parcel.

Step 2: Confirm the customs classification

Do not assign a CN code based only on a product description. Confirm the classification with the importer, customs representative or competent authority.

Step 3: Establish the transaction date and route

Record:

• Purchase date.
• Import date.
• Exporting country.
• Processing country.
• EU point of entry.
• Previous verification, if any.

Step 4: Obtain supporting evidence

Request the documents appropriate to the transaction rather than relying on a general origin statement.

Step 5: Connect records to inventory

Use stock, parcel, invoice, report or shipment references to preserve the documentary link.

Step 6: Review inconsistencies

Investigate when:

• The invoice and declaration show different suppliers.
• Weight or parcel details do not match.
• The declared mining country changes between documents.
• A G7 or GF reference cannot be connected to the goods.
• Goods described as traceable have no supporting records.
• The polishing country is being presented as mining origin.

Step 7: Escalate uncertainty

Do not complete a restricted transaction based on assumption. Contact the supplier, customs representative, national competent authority or qualified sanctions adviser.

Common Origin and Compliance Mistakes

Avoid:

• Treating “polished in India” as mining-origin proof.
• Calling Antwerp-sourced diamonds “Belgian-mined diamonds.”
• Treating a standard grading report as a complete origin certificate.
• Assuming a Kimberley Process certificate covers polished diamonds in the same way as rough shipments.
• Describing every KP-compliant diamond as fully ethical or fully traceable.
• Using 1 January 2026 as the current EU legal date for the amended polished-diamond requirement.
• Treating the 0.5-carat threshold as a universal sanctions exemption.
• Assuming third-country processing removes Russian origin.
• Claiming an exact mine when only country-level information is available.
• Treating a Due Diligence Statement as sufficient without supporting records.
• Mixing documented and undocumented inventory without controls.
• Publishing legal advice without a visible review date.
• Copying old AWDC or Commission dates without checking the current EUR-Lex text.

Frequently Asked Questions

Final Guidance

Mining origin, polishing location, grading location and trading route are separate facts.

For European diamond businesses, accurate language is no longer only a marketing concern. It can affect sanctions screening, import documentation and the reliability of customer statements.

The practical approach is:

• Identify what the documents actually prove.
• Do not replace mining origin with polishing or trading location.
• Check the latest EU legislation rather than relying on an old implementation date.
• Keep supplier, grading, shipment and origin records connected.
• Use claims that match the available evidence.
• Ask the relevant authority or adviser when a transaction is uncertain.

Dalila Diamonds can help trade clients source natural diamonds through Antwerp and provide the available grading, commercial and supplier documentation connected with each sourcing request. Documentation varies by diamond and transaction, so no sourcing statement should be presented as a legal compliance guarantee.
