For decades, most diamond buying conversations began with the same four characteristics.

Carat.

Colour.

Clarity.

Cut.

Those four factors still matter because they determine much of a natural diamond's quality, appearance and commercial positioning.

But in 2026, European jewellery businesses increasingly need to ask another question before approving a purchase:

Can the sourcing history of this diamond be supported by a credible documentation trail?

That question sits at the centre of the EU Diamond Due Diligence Statement on Diamond Origin.

The reason is simple. A natural diamond may travel through several countries before reaching a jewellery retailer.

A rough diamond could be mined in Botswana, sorted elsewhere, polished in India, graded by GIA, traded through Antwerp and eventually set into an engagement ring sold in Paris, Amsterdam, Munich or Milan.

Each location describes a different stage of the diamond's journey.

The polishing country is not necessarily the mining country.

The trading location is not necessarily the mining country.

The laboratory issuing the grading report does not automatically establish the complete mining history.

That distinction has become increasingly important under European sanctions and diamond-origin rules. The uploaded source makes the same central point: modern European buyers are moving away from relying solely on supplier assurances and toward sourcing systems where origin-verification efforts are supported by documentation.

For Dalila Diamonds, this creates a valuable B2B opportunity. European retailers increasingly need Antwerp natural-diamond sourcing that combines access to inventory with organised grading, commercial and available origin documentation.

Quick Answer: What Is the EU Diamond Due Diligence Statement?

The EU Diamond Due Diligence Statement is part of the origin-traceability evidence required for relevant polished natural-diamond imports into the European Union. Under the current 2026 framework reflected in the supplied source, the mandatory traceability-evidence requirement for relevant products under CN code 7102 39 00 applies from 24 April 2026. The statement supports the importer's position that the diamonds were not mined, processed or produced in Russia and that reasonable origin-verification efforts were made.

For a jewellery retailer, the easiest way to understand the requirement is:

the importer should not only know what the diamond is; it should also be able to explain why it reasonably believes the diamond falls outside prohibited Russian-origin supply.

Why the EU Diamond Due Diligence Statement Exists

The Due Diligence Statement forms part of the broader European and G7 response to Russian-origin diamonds entering international markets.

The difficulty is that natural diamonds do not always move directly from:

mine

to

European buyer.

A rough diamond may pass through:

sorting,

export,

manufacturing,

polishing,

grading,

wholesale trading,

and retail distribution.

A Russian-origin rough diamond could theoretically leave Russia, be processed in another manufacturing country and later appear as a polished diamond offered to an EU buyer.

If the only question asked were:

“Where was this diamond polished?”

the real mining origin could be obscured.

This is why European rules increasingly focus on evidence relating to origin rather than simply the final manufacturing location. The source specifically notes that for relevant polished natural diamonds under CN code 7102 39 00, current rules require mandatory traceability evidence including a due-diligence statement from 24 April 2026.

The Real Shift: From Supplier Trust to Documented Supplier Trust

Trust has always been fundamental to the natural-diamond trade.

Antwerp, in particular, has developed over generations around:

reputation,

relationships,

specialist expertise,

and long-term trading partnerships.

None of that disappears under a modern due-diligence framework.

What changes is the standard behind the trust.

Old approach:

“Our supplier says the diamonds are fine.”

Stronger 2026 approach:

“Our supplier provided the relevant origin information, we retained the supporting records and our stock system connects those records to the goods.”

The second position is significantly stronger because the business can demonstrate the process rather than relying on memory or verbal assurances alone.

Important Date Clarification for 2026

This is one of the most important parts of the rewritten article.

Earlier industry guidance referred to 1 January 2026.

The supplied source explains that AWDC introduced its operational Due Diligence Statement workflow from that date for in-scope natural polished diamonds of 0.50 ct and above.

However, the underlying EU provision was subsequently amended.

The current legal date reflected in the supplied material is:

24 April 2026

for mandatory traceability evidence, including the due-diligence statement, for relevant polished natural diamonds under CN code 7102 39 00.

AWDC Operational Date vs Current EU Legal Date

FrameworkDateAWDC operational DDS workflow1 January 2026Current amended EU legal requirement24 April 2026

These dates should not be presented as contradictory.

AWDC's operational process began earlier.

The EU legal provision was later amended.

For content published now, 24 April 2026 should be used when describing the current legal start date.

Which Natural Diamonds Are in Scope?

The supplied source states that AWDC's operational workflow applies to natural polished diamonds equal to or larger than 0.50 ct.

That threshold matters commercially because half-Carat-plus diamonds are not obscure wholesale goods.

They are common retail centre stones.

European jewellers regularly sell:

0.50 ct solitaires,

0.70 ct Ovals,

0.80 ct Emerald Cuts,

0.90 ct near-one-Carat stones,

and 1.00 ct or larger premium bridal diamonds.

That means the topic is relevant far beyond specialist rough-diamond importers.

It reaches directly into ordinary bridal, bespoke and high-value retail inventory.

Why the 0.50 ct Threshold Matters to Retailers

A retailer may assume sanctions and origin rules are mainly relevant to:

large import companies,

customs brokers,

rough-diamond traders,

or Antwerp dealers.

But a 0.70 ct certified engagement-ring diamond is ordinary retail stock.

If that stone enters the EU through a relevant import process, its upstream sourcing records matter.

This is why retailers should understand enough of the framework to ask suppliers good questions even when they do not personally file the customs declaration.

What Does the Due Diligence Statement Confirm?

The statement is fundamentally about reasonable origin verification.

According to the supplied source, the importer declares that:

the diamonds are not Russian origin,

and

sufficient efforts were made to verify that position.

This is a due-diligence concept rather than a claim that the importer personally observed the diamond being mined.

The importer needs a reasonable and documented basis for its conclusion.

Best Effort Does Not Mean Minimal Effort

The phrase best effort can be misunderstood.

It does not mean:

“we asked one question and accepted whatever answer we received.”

A stronger process may rely on:

supplier declarations,

Kimberley Process records,

G7 references,

GF references,

commercial documentation,

and origin information stored within the buyer's ERP or inventory system.

The practical takeaway is important:

do not leave origin information buried in someone's email inbox.

Connect it to the stock record.

Mining Origin Is the Core Question

Retailers need to understand four separate concepts:

Mining origin — where the rough diamond was extracted.

Polishing location — where the diamond was cut and polished.

Grading location — where its gemological characteristics were assessed.

Trading location — where the diamond was commercially sourced.

These can all be different.

Example Diamond Journey

Supply-Chain StageLocationMiningBotswanaPolishingIndiaGradingUnited StatesTradingBelgiumRetailGermany

If the customer asks:

“Where was it polished?”

the answer is India.

If the customer asks:

“Where did you source it?”

the answer may be Antwerp.

If the customer asks:

“Where was it graded?”

the answer may be the United States.

If the origin question is:

“Where was the rough diamond mined?”

the answer is Botswana.

Those statements are not interchangeable.

Why “Polished in India” Is Not Enough

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

There is nothing unusual about a natural diamond being polished there.

But:

polishing location is not mining origin.

A Russian rough diamond does not automatically become non-Russian simply because cutting and polishing happened in another country.

This is why retailers should never treat:

“Made in India”

or

“Polished in India”

as complete origin evidence.

Why “Sourced Through Antwerp” Is Not Mining Origin

The same distinction applies to Antwerp.

Antwerp is one of Europe's most important natural-diamond:

trading,

sorting,

wholesale,

logistics,

and sourcing centres.

A retailer can accurately say:

“This natural diamond was sourced through Antwerp.”

That explains the commercial route.

But:

“Belgian-origin diamond”

can imply geological origin and should not be used unless that description is factually supported.

Antwerp is the sourcing location.

Mining origin is a different piece of information.

What Evidence Can Support Diamond Origin Due Diligence?

The supplied source identifies several types of evidence that can support origin verification.

These can include:

Kimberley Process documentation,

G7 references,

GF references,

supplier declarations,

commercial invoices,

and origin information recorded in internal stock systems.

The retailer should understand what each document does rather than treating everything as one generic “diamond certificate.”

Due Diligence Documentation Comparison

Each answers a different question.

Why a GIA Certificate Is Not Enough

A GIA report can be extremely valuable.

It may document:

Carat,

Colour,

Clarity,

Cut,

measurements,

fluorescence,

and identifying features.

But it does not automatically prove the complete mining-origin history.

A retailer should therefore avoid statements such as:

“The diamond is GIA certified, so its origin is verified.”

A more precise explanation is:

“The GIA report confirms the diamond's grading characteristics. Supplier and origin records support the sourcing history separately.”

What Role Does the Kimberley Process Play?

Kimberley Process certificates relate to rough-diamond shipments.

They can form part of the upstream sourcing evidence behind polished natural diamonds.

A retail customer may never physically see the original KP documentation.

That does not make the upstream records irrelevant.

A strong rough-diamond documentation history can help create a stronger polished-diamond sourcing file later.

What Is a G7 Reference?

G7 references belong to the origin-verification side of the trade.

They are not:

GIA,

HRD,

or IGI grading reports.

This distinction is important because:

grading

and

origin verification

are different processes.

What Is a GF Number?

GF refers to qualifying grandfathered or legacy goods handled through the relevant framework.

Older diamonds may have entered commercial inventory before newer sanctions measures existed.

Their documentation history can therefore be different from newly imported goods.

Where GF applies, the relevant reference should stay connected to the commercial record.

The Aggregation Problem

Aggregation means diamonds from different sources or documentation histories are combined.

Commercially, this is normal in many areas of diamond trading.

Diamonds are commonly grouped by:

size,

Colour,

Clarity,

or manufacturing requirements.

The problem begins when:

well-documented goods are mixed with diamonds whose origin cannot be established.

That can weaken the entire documentation trail.

Example of Unknown-Origin Aggregation

Imagine a retailer has:

Parcel A

20 documented natural diamonds

current supplier records

clear purchasing history

Parcel B

8 older natural diamonds

unknown origin

no usable supplier records

If the two parcels are combined and the stones become indistinguishable, the retailer may lose the ability to preserve the stronger documentation history of Parcel A.

That is why traceable and unknown-origin goods should remain distinguishable where appropriate.

Mixed Origin Is Not the Same as Unknown Origin

A parcel containing diamonds documented as originating from:

Botswana,

Canada,

and Namibia

can still have a strong sourcing file.

That is mixed documented origin.

A parcel where nobody can identify the mining countries is a different issue.

Retail teams should understand the distinction.

This type of segregation can make:

resale,

export,

customer queries,

and compliance reviews

significantly easier.

Why Retailers Should Care Even If They Are Not Importers

A jeweller sourcing from an Antwerp wholesaler may never submit the customs declaration personally.

The formal import obligation may sit with another party.

But retailers still need good records.

Why?

Because the diamond can later be:

resold,

traded in,

re-exported,

insured,

upgraded,

or returned.

Customers may ask provenance questions years after the original purchase.

A retailer with a strong supplier file can answer confidently.

A retailer without one may have to reconstruct the sourcing story from scratch.

A Diamond Can Return Years Later

Imagine a customer buys a 1.00 ct natural-diamond engagement ring in 2026.

In 2032, they return because they want to:

upgrade,

sell,

reset,

trade in,

or move the jewellery internationally.

If the retailer retained:

the grading report,

supplier invoice,

available origin information,

and stock history,

the transaction is easier.

That is why documentation has value beyond the original import event.

What Should a Compliance-Ready Diamond File Contain?

A strong diamond file can combine:

RecordPurposeStock IDInternal identificationShapeProduct identificationCaratProduct identificationGIA / HRD / IGI reportGradingSupplier invoicePurchase recordPurchase dateCommercial chronologySupplier declarationOrigin supportG7 / GF referenceWhere relevantDDS informationWhere applicableShipment referenceLogistics continuityCustomer invoiceFinal transaction

The business does not necessarily need a physical folder.

A properly structured digital record is often more practical.

One Stone, One Digital Record

For an individually certified natural diamond, the retailer should ideally be able to search one stock number and retrieve:

grading report,

invoice,

supplier declaration,

shipment history,

origin notes,

and customer transaction history.

For example:

DL-2026-0751

might connect all information relating to one specific diamond.

That is much more reliable than asking employees to search:

emails,

shared drives,

accounting software,

and physical filing cabinets.

Melee Can Be Managed at Parcel Level

Not every small diamond needs an individual folder.

For calibrated melee, parcel-level records are often more practical.

Example:

Parcel ID: MEL-2026-018
Size: 1.3–1.5 mm
Colour: G–H
Clarity: VS–SI
Supplier: Antwerp Supplier A
Purchase Date: June 2026
Documentation Status: Current documented stock

The purpose is to preserve:

supplier identity,

parcel identity,

and commercial history.

Why Antwerp Matters in the 2026 Due-Diligence Environment

Antwerp's value is no longer only about inventory depth.

It is also about established diamond-trade infrastructure.

For European retailers, an experienced Antwerp supplier can offer access to:

natural-diamond inventory,

specialist documentation,

Diamond Office familiarity,

secure logistics,

grading connections,

and customs experience.

That can simplify downstream sourcing for retailers operating elsewhere in Europe.

Antwerp Is a Sourcing Route, Not a Mining Origin

Retailers should use precise language.

Good:

“Antwerp-sourced natural diamond.”

Potentially misleading:

“Belgian-origin diamond.”

unless mining-origin evidence genuinely supports that claim.

Precision protects both:

compliance

and

customer trust.

What European Retailers Should Ask Diamond Suppliers in 2026

The sourcing conversation should move beyond:

“What's your best price?”

Important questions now include:

Where was the diamond mined, where that information is available?

What documents support the origin information?

Does the upstream rough supply have KP records?

Does a G7 reference apply?

Does a GF reference apply to legacy goods?

Is a supplier declaration available?

Can the diamond be linked clearly to its grading report and invoice?

Has it been combined with stock whose documentation is unknown?

How long do you retain the relevant records?

Can those records be produced later if the stone is re-exported?

These are becoming normal professional buying questions.

Supplier A vs Supplier B

Consider two suppliers.

Supplier A

Lower price.

Fast delivery.

Strong inventory.

But:

origin answers are vague,

documents are difficult to retrieve,

and legacy goods are mixed with current inventory.

Supplier B

Slightly higher price.

Good inventory.

Clear invoice structure.

Grading reports connected to stock.

Supplier declarations available.

Legacy/current inventory separated.

Which one is genuinely lower risk?

In 2026, wholesale price alone does not tell the full story.

Retailers Should Also Think About Returns and Upgrades

A diamond sold today may return years later.

Ask suppliers:

Will the original documentation remain associated with the stone?

Can the diamond re-enter inventory after a return?

What happens if it needs to be exported later?

Can the sourcing records be retrieved quickly?

Good supplier processes should consider the complete commercial lifecycle, not only the first transaction.

Staff Training Does Not Need to Be Complicated

Retail employees do not need to become sanctions lawyers.

They should understand a few essential terms.

TermMeaningMining originWhere rough diamond was extractedPolishing locationWhere it was cut and polishedTrading locationWhere it was bought or soldGrading laboratoryWhere quality was assessedG7Applicable rough-origin verification frameworkGFApplicable grandfathered-goods frameworkDDSPolished import due diligence

That level of understanding prevents many inaccurate customer claims.

Better Customer Scripts

Customer asks:

“Is this an Antwerp diamond?”

Better answer:

“It was sourced through Antwerp. Antwerp is the trading and sourcing route; the mining origin is a separate part of the documentation.”

Customer asks:

“How do you know it isn't Russian?”

Better answer:

“We source through documented suppliers and retain available origin and trade records supporting our current natural-diamond inventory.”

Customer asks:

“Does the GIA certificate prove where it was mined?”

Better answer:

“The GIA report confirms the diamond's grading characteristics. Origin documentation is handled separately through the supply chain.”

Avoid Absolute Traceability Claims

Most customers do not want to read sanctions legislation.

They want confidence.

A simple statement may be enough:

“Our current natural-diamond inventory is sourced through documented trade channels, with supplier and grading records retained for the stones we purchase.”

That is often safer than:

“Everything is 100% traceable from mine to finger.”

unless the business genuinely has evidence supporting that exact claim.

Website Claims Retailers Should Review

Phrases to audit include:

100% ethical

fully traceable

conflict-free guaranteed

responsibly mined

mine-to-finger traceability

Belgian-origin diamonds

These terms can easily become broader than the records behind them.

Safer Website Language

Precise wording generally creates stronger trust than exaggerated marketing language.

Commercial Risk of Weak Documentation

The precise legal consequences depend on:

the Member State,

the transaction,

the import route,

and the facts.

But the commercial problems are easier to understand.

Weak records can cause:

shipment delays,

customs questions,

inventory uncertainty,

export difficulties,

audit issues,

and reputational risk.

The supplied source also notes that businesses should be prepared to produce supporting origin records during spot checks.

Record Retention

The source states that AWDC guidance requires relevant records to be retained for five years.

For jewellery retailers, longer commercial retention can often make sense.

A natural diamond may remain in the customer's possession for:

10,

20,

or even 30 years.

The customer can still return later for:

resizing,

upgrade,

insurance,

buyback,

or resale.

Keeping the commercial file connected to the diamond can create long-term value beyond the minimum regulatory requirement.

How Retailers Should Prepare Internally

A practical compliance system can be built around four areas.

Supplier Mapping

Know which suppliers can provide:

grading records,

origin-supporting documents,

G7/GF references where relevant,

and clear invoices.

Stock Mapping

Classify:

current documented,

legacy,

grandfathered,

buyback,

estate,

and unknown-origin goods.

Document Mapping

Choose one predictable storage system.

Do not leave records scattered across:

email,

paper,

accounting,

and individual staff folders.

Staff Mapping

Know who handles:

buying questions,

customer questions,

compliance issues,

and cross-border transactions.

Internal Retail Compliance Workflow

StageRetailer ActionSupplier selectedReview documentation capabilityStone offeredAsk origin questionsPurchase approvedRequest invoice + grading + sourcing recordsStone receivedCreate stock recordDocuments storedLink records to stock IDStone soldKeep customer record connectedCustomer returnsReopen original fileRe-export plannedReview documentation firstBuyback receivedCreate separate intake record

This is practical enough even for an independent jewellery retailer.

Compliance Can Become a Sales Advantage

Compliance is often described as administrative burden.

But better documentation can also improve retail positioning.

Natural-diamond customers increasingly compare:

natural vs lab-grown,

origin,

certification,

resale value,

provenance,

and long-term meaning.

A retailer who can explain those topics clearly can create more confidence than one who simply says:

“Don't worry, our supplier handles it.”

The source makes the same point: better compliance can strengthen the customer proposition rather than operating only as a back-office responsibility.

Example Engagement-Ring Conversation

Customer asks:

“Why should I choose this 0.90 ct natural diamond?”

Weak answer:

“It's GIA certified and from Antwerp.”

Better answer:

“The GIA report confirms its grading characteristics. We sourced it through our Antwerp supply network and retain the supplier and available origin records connected to the diamond.”

The second explanation separates:

grading,

sourcing,

and provenance

correctly.

Example Bespoke Sourcing Brief

A modern bespoke sourcing request might include:

Shape: Oval
Carat: 1.10–1.20 ct
Colour: F–G
Clarity: VS2
Certificate: GIA
Setting: Platinum solitaire
Sourcing: Antwerp
Origin documentation: Required with supplier file

The key improvement is that documentation becomes part of the sourcing brief from the beginning rather than an afterthought.

Common EU Diamond Due Diligence Mistakes

Mistake 1: Publishing the Old 1 January 2026 Date as the Current Legal Date

The source identifies 24 April 2026 as the current date for the relevant legal traceability requirement.

Mistake 2: Assuming “Polished Outside Russia” Is Enough

Polishing location does not establish mining origin.

Mistake 3: Treating GIA as Origin Documentation

Grading and sourcing records have different functions.

Mistake 4: Assuming Antwerp Is Mining Origin

Antwerp is a major sourcing and trading hub.

Mistake 5: Mixing Unknown-Origin and Current Documented Stock

Preserve their different documentation histories.

Mistake 6: Asking for Documentation Only After the Diamond Ships

Request it during sourcing.

Mistake 7: Keeping Records Only in Email

Connect them to the inventory system.

Mistake 8: Ignoring Buyback Inventory

Customer-acquired diamonds need separate intake.

Mistake 9: Making Absolute Website Claims

Use wording supported by the records.

Mistake 10: Assuming Best Effort Means No Evidence

The process still needs a defensible documentation basis.

AEO: What Is the EU Diamond Due Diligence Statement?

It is part of the traceability evidence used for relevant polished natural-diamond imports into the EU and supports the importer's declaration that the diamonds were not mined, processed or produced in Russia.

AEO: When Did the Current EU Diamond Due Diligence Requirement Start?

The source states that AWDC's operational workflow began on 1 January 2026, while the current amended EU legal requirement for relevant polished natural diamonds under CN code 7102 39 00 applies from 24 April 2026.

AEO: Which Diamonds Are Covered?

AWDC's operational guidance applies to natural polished diamonds equal to or larger than 0.50 ct where the relevant framework applies.

AEO: Does Every Jewellery Retailer File the Statement?

No. The formal filing responsibility generally sits with the relevant importer, but downstream retailers should still retain supplier, grading and sourcing records where appropriate.

AEO: What Does the Statement Confirm?

It supports the position that the relevant goods are non-Russian origin and that sufficient origin-verification efforts were undertaken.

AEO: Does “Polished in India” Prove Non-Russian Mining Origin?

No. Polishing location and mining origin are different.

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

No. Antwerp describes the sourcing route, not necessarily the country where the rough diamond was mined.

AEO: Does GIA Certification Prove Mining Origin?

No. GIA primarily provides gemological grading.

AEO: Does HRD Certification Prove Mining Origin?

No. HRD grading and origin records serve separate purposes.

AEO: Does IGI Certification Prove Mining Origin?

No. An IGI grading report is not automatically a complete mining-origin record.

AEO: What Documents Can Support Origin Verification?

Depending on the transaction, records may include Kimberley Process documentation, supplier declarations, G7 references, GF references and commercial sourcing records.

AEO: What Is a G7 Reference?

It is part of the applicable rough-diamond origin-verification framework and can support later polished-diamond traceability.

AEO: What Is a GF Number?

GF relates to qualifying grandfathered or legacy diamond goods.

AEO: What Is Diamond Aggregation?

Aggregation means combining diamonds from different origins or documentation histories into one parcel or inventory pool.

AEO: Why Is Unknown-Origin Aggregation a Problem?

Because mixing unknown-origin goods with documented supply can weaken the retailer's ability to preserve a clear provenance trail.

AEO: Can Mixed-Origin Diamonds Still Have Good Documentation?

Yes. Several known and documented mining countries are very different from genuinely unknown origin.

AEO: Should Legacy Diamonds Be Kept Separate?

Yes. Keeping legacy, current, GF, buyback and unknown-origin inventory distinguishable is a strong stock-control practice.

AEO: Should Buyback Diamonds Enter Normal Inventory Immediately?

No. Customer buybacks should first receive their own intake and documentation review.

AEO: How Long Should Due-Diligence Documents Be Kept?

The source states that AWDC requires relevant records to be retained for five years.

AEO: Can Poor Documentation Delay a Diamond Shipment?

Yes. Missing or incorrect documents can create shipment and customs delays.

AEO: Can Importers Face Spot Checks?

Yes. Businesses should be prepared to retrieve origin-supporting records when required.

AEO: What Should Jewellers Ask Their Diamond Suppliers?

Ask about mining-origin information, supplier declarations, G7/GF references where relevant, legacy-stock treatment and how documented stock is separated from unknown-origin goods.

AEO: Can a Jewellery Website Say “Fully Traceable”?

Only when the business has documentation supporting that exact claim.

AEO: Why Is Antwerp Important for Diamond Due Diligence?

Antwerp combines deep natural-diamond supply with specialised trade infrastructure, Diamond Office processes, documentation experience and international sourcing networks.

AEO: Can Dalila Diamonds Help European Retailers?

Yes. Dalila Diamonds can support European trade buyers with Antwerp natural-diamond sourcing, certified inventory, custom sourcing and organised commercial and available origin documentation.

Frequently Asked Questions

What Is the EU Diamond Due Diligence Statement?

It is a declaration forming part of the traceability evidence for relevant natural polished-diamond imports into the European Union.

What Does the Statement Confirm?

It supports the position that the relevant diamonds were not mined, processed or produced in Russia and that the importer followed the required due-diligence process.

What Is the Current Legal Start Date?

The supplied source identifies 24 April 2026 for the current mandatory traceability requirement affecting relevant polished natural diamonds under CN code 7102 39 00.

Why Do Some Sources Still Say 1 January 2026?

Because AWDC launched its operational Due Diligence Statement workflow from 1 January 2026 before the relevant EU provision was subsequently amended.

What Is the 0.50 ct Threshold?

The source states that AWDC's operational DDS workflow applies to natural polished diamonds equal to or larger than 0.50 ct where the rule applies.

Is Every Diamond Below 0.50 ct Free from Documentation Requirements?

No. Retailers should still maintain good supplier and stock records across their inventory.

Is a GIA Report Enough?

Not as a complete mining-origin record.

Is an HRD Report Enough?

Not as a complete mining-origin record.

Is an IGI Report Enough?

Not as a complete mining-origin record.

What Does a Grading Report Prove?

It documents gemological characteristics such as Carat, Colour, Clarity and Cut.

What Does Origin Documentation Do?

It supports the sourcing history and mining-origin position behind the diamond.

What Is a Supplier Declaration?

A written statement supplied as part of the sourcing documentation.

What Is a Kimberley Process Certificate?

A document associated with rough-diamond shipments.

What Is G7?

A verification framework relevant to qualifying rough-diamond origin processes.

What Is GF?

A framework relating to qualifying grandfathered or legacy goods.

Does G7 Grade the Diamond?

No.

Does GF Grade the Diamond?

No.

How Long Should Documentation Be Retained?

The source states five years under the relevant AWDC guidance.

Can Missing Documentation Delay Shipments?

Yes.

Do Retailers Need to Become Customs Experts?

No. They need to know when to involve the importer, customs adviser or specialist supplier.

Can Retailers Say “Belgian Diamond”?

It is usually more precise to say “sourced through Antwerp” when Antwerp refers to the commercial trading route.

Can Retailers Say “Indian Diamond” When It Was Polished in India?

Only if India is actually the documented mining origin. Otherwise, say “polished in India.”

Why Is Antwerp Important in 2026?

Antwerp remains important because of its supply depth and specialised diamond-trade infrastructure.

Can Dalila Diamonds Support Compliance-Focused Diamond Sourcing?

Yes. Dalila Diamonds can support European trade buyers seeking natural diamonds through Antwerp with grading, supplier and available origin records organised for modern B2B sourcing requirements.

Conclusion: Diamond Quality Is No Longer the Only Record That Matters

A natural diamond is still judged first by the characteristics customers understand best.

Its:

Cut,

Colour,

Clarity,

Carat,

shape,

and brilliance

remain fundamental.

But the 2026 European market increasingly adds another layer:

a defensible documentation history.

That does not mean every retailer must become a customs specialist.

It means professional jewellery businesses should build better sourcing habits.

Ask where the diamond was mined when that information is available.

Do not confuse mining origin with polishing location.

Do not confuse Antwerp sourcing with geological origin.

Keep grading reports separate from origin records.

Retain supplier declarations where relevant.

Understand the role of KP, G7, GF and the Due Diligence Statement.

Keep unknown-origin and current documented stock distinguishable.

Track buybacks separately.

Preserve records even after the diamond is sold.

Train staff to explain provenance accurately.

And avoid broad claims such as “100% traceable” unless your documentation genuinely supports them.

The source's final practical message is particularly important: under the current version reflected in the document, the relevant mandatory EU polished-diamond traceability requirement applies from 24 April 2026, rather than relying on older 1 January wording.

For Dalila Diamonds, this reinforces a commercially important position in the European natural-diamond trade.

One retailer may need a 0.70 ct Round Brilliant.

Another may need a 1.10 ct Oval.

Another may need calibrated melee.

Another may need matched side stones.

Another may simply need confidence that the supplier behind the diamond understands which records should remain connected to the stone.

The inventory requirement changes.

The jewellery changes.

The customer changes.

But the sourcing principle remains increasingly consistent:

in the 2026 European natural-diamond market, gemological quality explains why the diamond is desirable; due diligence explains why the sourcing history is credible.
