For years, jewellery retailers across Europe have used simple phrases to explain where a diamond came from.

A stone might be described as:

“Antwerp sourced”

“polished in India”

“Belgian supplied”

or

“GIA certified”.

All of those statements may be factually useful.

None of them, by itself, necessarily answers the most important origin question:

Where was the rough natural diamond actually mined?

That distinction matters more in 2026 than it did a few years ago.

A diamond can be mined in Botswana, polished in India, graded by GIA, traded through Antwerp and eventually sold by a jeweller in Paris or Amsterdam. Every one of those locations describes a genuine stage in the supply chain, but only Botswana would describe the mining origin in that example. The source article makes exactly this distinction: polishing location, grading location and trading route are different from the country where the rough diamond was originally extracted.

For European retailers, this is no longer only terminology.

EU sanctions rules targeting Russian-origin diamonds require origin evidence in certain import situations. Current EU law states that importers must provide evidence of the country of origin of diamonds or diamond-containing inputs used for processing in third countries. For polished natural diamonds under CN code 7102 39 00, mandatory traceability evidence, including a due-diligence statement confirming that the diamonds were not mined, processed or produced in Russia, applies from 24 April 2026.

AWDC’s operational Antwerp guidance had introduced its Due Diligence Statement workflow from 1 January 2026 for in-scope natural polished diamonds of 0.50 ct and above, while the amended EU legal text now specifies 24 April 2026 for mandatory traceability evidence under CN 7102 39 00.

For retailers, the practical lesson is simple:

“Polished in India” is useful supply-chain information, but it is not proof of mining origin.

Quick Answer: What Is Diamond Mining Origin?

Diamond mining origin means the country where the rough natural diamond was extracted from the earth. It is different from polishing location, grading location and trading location. A natural diamond can be mined in one country, cut and polished in another, graded by a laboratory elsewhere and sold through Antwerp. Under current EU sanctions rules, origin evidence matters because Russian-origin diamonds can remain restricted even when they have been processed in a third country.

A practical retailer rule is:

never use polishing location as a substitute for mining-origin evidence.

Mining Origin vs Polishing Location

The difference is straightforward.

Mining origin means where the rough diamond was extracted.

Polishing location means where that rough diamond was cut and faceted into a polished stone.

These are entirely different stages of the supply chain. The source article correctly notes that a diamond polished in India may have been mined in Botswana, Canada, Namibia, South Africa, Angola or another producing country.

India is one of the world’s most important diamond cutting and polishing centres.

Surat in particular processes enormous volumes of global diamond supply.

That does not make “India” the mining origin of every diamond polished there.

Likewise, Antwerp is one of the world’s most important diamond trading centres.

That does not make “Belgium” the geological origin of every diamond sourced through Antwerp.

A Diamond Can Have Several Countries in Its Supply Chain

Consider this example:

StageCountryMiningBotswanaSortingBotswana / another trading centrePolishingIndiaGradingUnited StatesWholesale sourcingBelgiumRetail saleFrance

Every line can be accurate.

But only the first answers:

Where was the diamond mined?

That distinction becomes particularly important in compliance discussions.

Why “Polished in India” Is Not Enough

EU sanctions focus on the origin of the diamond, not simply on where it underwent its last commercial transformation.

The EU restrictions progressively expanded to Russian diamonds processed in third countries. From 1 September 2024, the prohibition also covers relevant Russian-origin diamonds and certain diamond products processed in third countries at or above the applicable 0.50 ct threshold.

This means processing a Russian-origin diamond in another country does not automatically turn that diamond into a non-Russian-origin stone for sanctions purposes.

That is the critical compliance principle.

If a Russian rough diamond is cut and polished in India, the polishing location does not erase its Russian mining origin.

Why the Third-Country Rule Matters

Without a third-country processing rule, origin restrictions could be bypassed easily.

A restricted diamond could theoretically move:

Russia → polishing country → Europe

and then be described only according to its polishing location.

The EU framework specifically addresses this type of indirect route.

For jewellery retailers, that means a supplier explanation such as:

“These stones are fine because they were polished in India.”

is incomplete.

A better supplier answer is:

“These diamonds were polished in India, and our documentation supports the declared non-Russian mining origin.”

That answer separates processing from origin.

Why “Sourced from Antwerp” Is Also Not the Mining Origin

Antwerp remains an important and credible sourcing location.

For European jewellers, Antwerp offers access to:

natural-diamond wholesalers,

Diamond Office infrastructure,

grading connections,

specialist logistics,

trade expertise,

matched pairs,

melee,

and bespoke sourcing.

The source article correctly highlights these commercial strengths.

But “Antwerp sourced” is still a trading-route statement.

It does not mean:

“mined in Belgium.”

Belgium is not the mining source simply because the stone passed through the Antwerp market.

Better Retail Language

Instead of:

“This is a Belgian diamond.”

say:

“This natural diamond was sourced through Antwerp.”

Instead of:

“This is an Indian diamond.”

when you mean polishing,

say:

“This diamond was polished in India.”

If the actual mining origin is documented:

“This diamond was mined in Botswana, polished in India and sourced through Antwerp.”

That is much more precise.

Why Origin Language Matters for SEO Too

Jewellery websites often use terms loosely because they sound commercially attractive.

Examples include:

Belgian diamonds,

Antwerp diamonds,

Indian diamonds,

European diamonds,

ethical diamonds,

traceable diamonds,

responsibly sourced diamonds.

Some of these phrases may be appropriate in context.

But the wording should match what the business can actually prove.

For SEO, precision is better than broad claims.

A page targeting Antwerp diamond sourcing can absolutely say the stone was sourced through Antwerp.

It should not imply Antwerp mining origin.

The EU Rule Is About Evidence, Not Just Marketing Language

The current EU framework requires importers to provide evidence of origin for the relevant diamonds and inputs processed in third countries. For the applicable polished natural diamonds under CN 7102 39 00, the law now requires traceability evidence including a due-diligence statement from 24 April 2026.

The objective is therefore not simply to use correct terminology.

It is to support the terminology with records.

What the Due Diligence Statement Does

AWDC’s 2026 guidance describes the Due Diligence Statement as an importer declaration that:

the diamonds are not of Russian origin,

and

sufficient efforts were made to verify that conclusion.

This is a best-efforts due-diligence framework supported by records.

It is not simply a marketing certificate saying:

“non-Russian.”

Which Polished Diamonds Are in Scope?

AWDC states that its 2026 Due Diligence Statement workflow applies to natural polished diamonds equal to or larger than 0.50 ct.

Current EU law should still be checked according to:

CN classification,

transaction,

shipment route,

and current sanctions text.

Retailers who are not the formal importer may not personally submit the statement.

But they still benefit from buying from suppliers whose records support the imported goods.

Important 2026 Date Clarification

The supplied draft states that the Due Diligence Statement requirement started on 1 January 2026.

AWDC does indeed describe its operational process as applying from 1 January 2026.

However, Regulation (EU) 2026/506 amended the EU legal text so that mandatory traceability evidence, including the due-diligence statement for products under CN 7102 39 00, applies from 24 April 2026.

For the published article, the safest wording is:

“AWDC introduced the operational DDS workflow from 1 January 2026, while the amended EU legal text specifies 24 April 2026 for mandatory traceability evidence for the relevant polished natural diamonds.”

That reflects both primary sources accurately.

What European Retailers Should Ask Suppliers

The source article recommends better supplier questions before buying.

That is exactly the right approach.

The buying conversation should not begin after the parcel arrives.

Ask before purchase.

Supplier Questions for 2026

QuestionWhy It MattersWhat is the mining origin?Establishes the relevant origin claimWhat records support that origin?Tests documentary supportWhere was the diamond polished?Identifies processing routeWas it processed in a third country?Relevant to sanctions analysisIs this current or legacy stock?Different documentation historiesDoes a G7 reference apply?May support upstream rough verificationDoes a GF number apply?May indicate grandfathered goodsIs a supplier declaration available?Can support due diligenceHas the stone been mixed with unknown-origin goods?Aggregation riskCan documents be retrieved later?Important for resale/export

These questions should feel normal.

A professional supplier operating in the 2026 European trade environment should expect them.

What if the Supplier Does Not Know the Exact Mine?

Mining-origin documentation does not always mean the retailer knows the exact mine.

The relevant information may be recorded at country level depending on the specific documentation and transaction.

The important distinction is between:

documented country-of-origin information

and

unsupported assumptions.

A supplier saying:

“The exact mine is not identified, but the country-of-mining origin is supported by our supply documentation.”

is very different from:

“We do not know, but the stone was polished in India.”

What Documents Can Support the Origin File?

AWDC guidance states that importers can use several forms of evidence in their verification process, including:

Kimberley Process documentation,

G7 or GF references,

or supplier declarations.

Retailers farther down the chain may therefore see different combinations of records depending on the stone.

A practical polished-diamond file might include:

grading report,

supplier invoice,

supplier declaration,

stock number,

purchase date,

origin notes,

G7/GF information where relevant,

shipment information,

and customer invoice after sale.

Strong Documentation Chain

DocumentPurposeGIA/HRD/IGI reportGemological qualitySupplier invoiceCommercial identityStock numberInternal controlSupplier origin declarationOrigin-supporting evidenceG7 referenceUpstream rough verification where applicableGF referenceGrandfathered-goods history where applicableDDS informationPolished-diamond import due diligenceShipment referenceSupply-chain continuity

The documents should be linked rather than scattered across unrelated systems.

Certification Is Not the Same as Mining Origin

This deserves its own section because it is one of the most common consumer misunderstandings.

A GIA, HRD or IGI grading report helps explain:

Carat,

Colour,

Clarity,

Cut,

measurements,

fluorescence,

and identifying features.

It does not automatically establish a complete mining-origin history.

The source article makes this distinction directly.

A customer asking:

“Is this a good diamond?”

may need grading information.

A customer asking:

“Where was this diamond mined?”

is asking a different question.

GIA vs Origin Documentation

QuestionBest RecordWhat is the Carat?Grading reportWhat is the Colour?Grading reportWhat is the Clarity?Grading reportWhat is the Cut?Grading reportWhere was it mined?Origin/supplier documentationWas it polished in India?Processing/supplier recordWas it sourced through Antwerp?Supplier/commercial recordWas it grandfathered?GF/legacy documentation where applicable

This is the simplest way to explain the distinction to staff.

G7 References and Mining Origin

The G7 framework is connected with origin verification for qualifying rough diamonds.

AWDC explains that rough diamonds passing G7 verification through Antwerp receive a G7 certificate/reference which can later support the origin history of polished goods derived from verified rough.

A G7 reference is therefore not another version of a GIA certificate.

It is part of the trade and origin-verification framework.

GF References and Legacy Goods

GF references belong to grandfathered or legacy goods handled through the applicable framework.

A retailer should understand the distinction because a supplier may say:

“This is GF stock.”

That does not describe Colour or Clarity.

It describes part of the goods’ historical/compliance status.

Why Aggregation Matters to Mining Origin

Origin can become difficult to explain when traceable goods are mixed with diamonds of unknown origin.

The retailer should therefore ask suppliers how they handle aggregation.

For example:

Are multiple mining origins recorded?

Are current goods mixed with old unknown stock?

Are buyback stones kept separate?

Are parcel references preserved?

This is particularly important for melee and small diamonds.

Example: Documented Mixed-Origin Parcel

Suppose a supplier has:

Botswana-origin diamonds,

Canadian-origin diamonds,

and Namibian-origin diamonds.

If those origins remain documented and the supplier can support the parcel’s record, multiple origins do not automatically mean poor sourcing control.

The problem is not:

more than one origin.

The problem is:

origin unknown.

Example: Weak Mixed Parcel

Supplier description:

0.50–0.70 ct
G–H
VS–SI
Mixed origin
No source details
No supplier declaration

That parcel may be commercially attractive.

It needs more questions before purchase.

Why This Matters for Engagement Rings

Engagement-ring customers increasingly ask about more than the 4Cs.

The source article notes that bridal buyers may ask whether the diamond is natural, certified and responsibly sourced, particularly because engagement rings are often a customer's first high-value jewellery purchase.

A jeweller should be able to answer without improvising.

A good explanation is:

“This is a natural diamond with a recognised grading report. It was sourced through our Antwerp supplier, and we retain the available sourcing documentation associated with the stone.”

If mining origin is documented specifically, add it.

If it is not, do not invent it.

Why This Matters Even More for Bespoke Jewellery

Bespoke clients often expect more detailed sourcing conversations.

A client may ask:

Why this Oval?

Why this particular Colour?

Why this certificate?

Where was it sourced?

Where was it mined?

Can I see documentation?

The source article correctly notes that sourcing on demand creates an opportunity to request the documentation before committing to the stone.

That is a major advantage.

Example Bespoke Brief

Shape: Oval
Carat: 1.10–1.20 ct
Colour: F–G
Clarity: VS2
Certificate: GIA
Polishing location: India
Sourcing route: Antwerp
Mining-origin documentation: Requested before confirmation

This is a more professional buying brief than:

“Find me a 1.20 ct Indian Oval.”

What About Diamonds Already in Stock?

Many European jewellers have old inventory.

The source recommends reviewing:

purchase dates,

supplier invoices,

grading reports,

stock records,

and available declarations.

Do not mix poorly documented old inventory casually with newly sourced current goods.

The different documentation histories should remain visible.

Legacy Stock Categories

A retailer can classify stock as:

CategoryTreatmentCurrent documentedNormal current inventoryLegacy documentedHistorical records retainedGrandfathered/GFSeparate compliance historyCustomer buybackSeparate intakeEstateHistorical/secondary-market reviewUnknown-originKeep under reviewCustomer-ownedNot retailer inventory

The terminology can vary internally.

The purpose is clarity.

Diamond Buybacks Need Extra Care

A customer may bring:

an inherited diamond,

a divorce-related engagement ring,

an estate stone,

or a privately purchased diamond.

It may have a GIA report.

It may not have origin documentation.

Do not assume:

certificate = mining history.

Buybacks should be recorded separately before entering resale stock.

Supplier Questionnaires Are Becoming Normal

The source article recommends a standard supplier questionnaire.

That is particularly useful for:

multi-store retailers,

buying groups,

e-commerce jewellery brands,

and businesses using several wholesalers.

A questionnaire creates consistency.

Example Supplier Questionnaire

Where was the diamond mined, where known?

What evidence supports the declared origin?

Where was it cut and polished?

Does a G7 reference apply?

Does a GF reference apply?

Can you provide a supplier origin declaration?

Has the stone been mixed with unknown-origin stock?

How long do you retain origin documentation?

Can records be retrieved if the stone is later exported?

The questionnaire does not need to be confrontational.

It is normal supplier governance.

How to Explain Mining Origin to Customers

Most customers do not want a sanctions lecture.

The source suggests simple and honest language, which is the right approach.

Use:

“The country where a diamond is polished is not necessarily the country where it was mined. We work with documented suppliers and keep the available sourcing records associated with our natural diamonds.”

That is much better than:

“It was polished in India, so it is Indian.”

Avoid Absolute Provenance Claims

Retailers should be careful with language such as:

“fully traceable”

“100% ethical”

“guaranteed conflict-free”

“mine-to-finger”

“Belgian-origin”

unless their documentation supports exactly that claim.

A better SEO-safe phrasing might be:

“Natural diamonds sourced through documented Antwerp trade channels, with supplier and grading records retained for current inventory.”

That is strong without overclaiming.

Mining Origin Can Become a Brand Asset

Origin documentation is often framed as a compliance burden.

For retailers, it can also strengthen customer trust.

A business that can calmly explain:

where the diamond was sourced,

where it was polished,

what grading report it has,

and what origin records exist

looks more professional.

This is particularly valuable in higher-value natural-diamond sales.

Natural Diamond Provenance vs Lab-Grown Comparison

Customers increasingly compare natural and lab-grown diamonds partly through sourcing questions.

A natural-diamond retailer should not respond by making exaggerated claims.

The strongest natural-diamond position is often:

clear grading,

clear sourcing language,

documented commercial records,

and accurate explanation of natural geological origin.

That is more credible than vague rhetoric.

Why European Customers Often Prefer Factual Language

The source article argues that European buyers frequently respond better to straightforward provenance explanations than dramatic marketing claims.

That approach fits this subject perfectly.

Say what you know.

Say what the document proves.

Do not imply what it does not prove.

What Happens if Retailers Ignore Mining Origin?

Ignoring the distinction between mining and polishing can create several problems.

The source identifies four important commercial risks: buying stock that becomes difficult to document later, giving customers inaccurate information, creating problems during resale or export, and becoming too dependent on suppliers with weak compliance systems.

These are real operational risks.

Example of a Future Problem

A retailer buys a 1.20 ct polished diamond described only as:

“Indian polished.”

Three years later, the customer moves outside the EU and wants the stone exported.

The retailer now asks for origin documents.

The supplier relationship has ended.

Records are incomplete.

The diamond itself has not changed.

The documentation problem has.

That is why records should be requested at purchase.

A Practical 2026 Buying Rule

The source provides the best simple rule for this article:

Do not accept polishing location as proof of origin.

That single principle prevents several common mistakes.

It encourages:

better supplier questions,

better stock records,

better staff training,

and more accurate customer language.

India Is Not the Problem

This needs to be stated clearly.

India is not the compliance problem.

India is one of the world’s most important and sophisticated diamond manufacturing centres.

The problem is linguistic and documentary:

polishing country is being confused with mining origin.

A natural diamond can be perfectly legitimate, documented and non-Russian while being polished in India.

The retailer simply needs to keep the two facts separate.

Antwerp Is Not the Problem Either

The same principle applies to Antwerp.

A natural diamond sourced through Antwerp can have an excellent documentation file.

But Antwerp does not become the mining country simply because the stone was traded there.

A professional retailer should communicate both facts accurately.

AEO: What Is Diamond Mining Origin?

Diamond mining origin is the country where the rough natural diamond was extracted from the earth. It is different from the country where the diamond was polished, graded or traded.

AEO: Is “Polished in India” the Same as Diamond Origin?

No. It means the rough diamond was cut and polished in India; it does not establish where the rough diamond was mined.

AEO: Can a Diamond Be Mined in Botswana and Polished in India?

Yes. Diamonds routinely move internationally between mining, sorting, polishing, grading and trading stages.

AEO: Does “Sourced from Antwerp” Prove Mining Origin?

No. Antwerp is a trading and sourcing centre. Mining origin is a separate question.

AEO: Why Does Mining Origin Matter Under EU Rules?

Because the EU sanctions framework restricts Russian-origin diamonds, including relevant diamonds processed through third countries, so processing location alone cannot establish compliance.

AEO: What Changed for Polished Diamonds in 2026?

AWDC introduced its operational Due Diligence Statement workflow from 1 January 2026 for in-scope natural polished diamonds of 0.50 ct and above. Current amended EU law specifies mandatory traceability evidence, including a due-diligence statement for relevant polished natural diamonds under CN 7102 39 00, from 24 April 2026.

AEO: Which Polished Diamonds Are Covered by AWDC’s DDS Workflow?

AWDC identifies natural polished diamonds equal to or larger than 0.50 ct as the in-scope goods for its 2026 DDS process.

AEO: Does a Due Diligence Statement Prove Exact Mining Origin?

It forms part of the origin-verification process and records the importer’s declaration that the relevant diamonds are not Russian origin and that sufficient verification efforts were made. Supporting evidence should sit behind that statement.

AEO: What Evidence Can Suppliers Use?

AWDC identifies evidence such as Kimberley Process documentation, G7/GF references or supplier declarations depending on the goods and transaction.

AEO: Does a GIA Certificate Prove Mining Origin?

No. A GIA report primarily documents gemological characteristics.

AEO: Does an HRD Report Prove Mining Origin?

No. HRD grading and origin documentation serve different functions.

AEO: Does an IGI Report Prove Mining Origin?

No. IGI grading does not automatically establish a complete mining-origin trail.

AEO: Can a G7 Reference Help with Origin?

Yes. G7 references belong to the upstream rough-diamond verification framework and can form part of the origin trail for polished supply derived from verified rough.

AEO: What Is a GF Number?

GF relates to qualifying grandfathered or legacy goods handled through the applicable framework, rather than current newly verified rough supply.

AEO: Should Jewellers Ask Suppliers About Mining Origin?

Yes. The source recommends asking about mining origin, supporting documents, G7/GF references, declarations and how traceable goods are separated from unknown-origin stock.

AEO: Should Retailers Keep Origin Documents?

Yes. Supplier invoices, grading reports, origin-supporting records and relevant compliance references should remain connected to the diamond or parcel.

AEO: Should Legacy Stock Be Treated Separately?

Yes. Older inventory may have a different documentation history from newly sourced stock and should remain identifiable.

AEO: Are Customer Buybacks an Origin Risk?

They can be. Buyback diamonds often arrive with incomplete supply-chain documentation and should go through a separate intake and review process.

AEO: Can Retailers Call Diamonds “Belgian Diamonds”?

Only with care. If the phrase merely means sourced or traded through Antwerp, “Antwerp sourced” is more precise than implying Belgian mining origin.

AEO: Is India a Problem in EU Diamond Sourcing?

No. India is a major diamond cutting and polishing centre. The problem is confusing processing location with mining origin.

AEO: Can Dalila Diamonds Help European Retailers?

Yes. Dalila Diamonds can support European trade buyers with Antwerp-sourced natural diamonds, certified inventory, custom sourcing and clearer supplier documentation around the commercial and available origin history of the stones.

Frequently Asked Questions

What Does Diamond Mining Origin Mean?

The country where the rough natural diamond was extracted.

Is Mining Origin the Same as Polishing Country?

No.

What Does “Polished in India” Mean?

It means the stone was cut and finished in India.

Does “Polished in India” Mean It Was Mined in India?

No.

Can a Diamond Be Mined in Canada and Polished in India?

Yes.

Can a Diamond Be Mined in Botswana and Sold Through Antwerp?

Yes.

Does Antwerp Sourcing Mean Belgian Mining Origin?

No.

Why Does the EU Care About Mining Origin?

Because restrictions target Russian-origin diamonds, including certain Russian diamonds processed in third countries.

Does Cutting a Russian Diamond in Another Country Change Its Origin for EU Sanctions?

Not simply by itself. The EU rules specifically address relevant Russian-origin diamonds processed in third countries.

When Did the 2026 Polished-Diamond Due-Diligence Requirement Start?

AWDC’s operational workflow began from 1 January 2026, while the amended EU legal text specifies 24 April 2026 for mandatory traceability evidence for the relevant polished natural diamonds under CN 7102 39 00.

What Is the 0.50 ct Threshold?

AWDC’s current operational DDS guidance applies to natural polished diamonds equal to or larger than 0.50 ct.

Do Retailers Personally File the DDS?

Only the relevant importer handling the customs declaration has the formal filing obligation. Retailers buying from suppliers should still maintain appropriate commercial and sourcing records.

What Is a Supplier Origin Declaration?

A supplier statement supporting the declared mining-origin information and due-diligence record.

Is a Supplier Declaration Always Enough?

The evidence needed depends on the goods and transaction. AWDC says supplier declarations can form part of the reasonable-verification evidence.

Is GIA an Origin Certificate?

No.

Is HRD an Origin Certificate?

No.

Is IGI an Origin Certificate?

No.

What Does GIA Tell Me?

Diamond grading characteristics.

What Does G7 Tell Me?

Information related to qualifying rough-diamond origin verification.

What Does GF Tell Me?

Information related to qualifying grandfathered goods.

What Should Retailers Ask Before Buying?

Mining origin, polishing country, supplier documentation, relevant G7/GF references and whether the stock has been mixed with goods of unknown origin.

What Should Retailers Do with Older Stock?

Review invoices, certificates, purchase dates and available supplier records and keep it separate from current documented stock when appropriate.

What Should Retailers Do with Buyback Diamonds?

Create a separate intake record and document what is and is not known.

Can a Retailer Say “Fully Traceable”?

Only if the documentation genuinely supports that level of traceability.

What Is Safer Website Language?

“Natural diamonds sourced through documented trade channels, with supplier and grading records retained for current inventory.”

Why Is Antwerp Still Important?

Because it combines deep natural-diamond supply with specialist trade infrastructure, Diamond Office processes, documentation expertise and custom sourcing.

Can Dalila Diamonds Source Specific Diamonds?

Yes. Dalila Diamonds can support trade clients seeking specific Carat, shape, Colour, Clarity and certified natural-diamond requirements through Antwerp.

Conclusion: Mining Origin Is Where the Diamond Story Begins

A polished diamond may have travelled through several countries before reaching a jewellery store.

It may be:

mined in Botswana,

polished in India,

graded by GIA,

sourced through Antwerp,

and sold in Amsterdam.

Each stage matters.

But each stage answers a different question.

The mining origin tells you where the natural diamond began.

The polishing country tells you where human craftsmanship transformed the rough.

The grading laboratory tells you where the stone was assessed.

The trading hub tells you where it entered the commercial supply chain.

The current EU sanctions framework makes that distinction more important because relevant Russian-origin diamonds remain subject to restrictions even when they have been processed through third countries.

For European jewellery retailers, the practical response is not complicated.

Do not accept polishing location as proof of mining origin.

Do not call Antwerp the mining country.

Do not use a GIA, HRD or IGI report as a substitute for origin records.

Ask suppliers what evidence supports the declared origin.

Store origin records with the commercial file.

Keep legacy and buyback goods identifiable.

Train staff to use accurate terminology.

Review website provenance claims.

And when the documentation does not support a specific origin statement, do not guess.

The source article reaches the same conclusion: the old shorthand of “polished in India”, “Antwerp sourced” or “GIA certified” is no longer enough to describe where a diamond truly comes from; modern retailers need to understand the complete distinction between mining, processing, grading and trading.

For Dalila Diamonds, that creates a clear sourcing proposition.

A retailer may need a Round Brilliant.

Another may need an Oval.

Another may need a matched pair.

Another may need a stone polished in India but supported by a clearer non-Russian origin file.

The diamond changes.

The trade route changes.

But one rule should not:

where a diamond was polished tells you how it was transformed; where it was mined tells you where its natural origin actually begins.
