A customer walks into a jewellery store looking for a very specific natural diamond.

They want a 2.00 ct Round Brilliant, G Colour, VS2 Clarity, Excellent Cut, ideally with a recognised grading report and strong proportions.

A few years ago, that request might have felt relatively straightforward.

In 2026, the answer can be more complicated.

The diamond may still exist somewhere in the global market. But the exact combination of size, Cut, Colour, Clarity, documentation, price and delivery timing may not be sitting inside the retailer’s ordinary supplier inventory at that moment.

That distinction matters because the phrase “diamond shortage” can easily become misleading.

There is not a universal shortage affecting every natural diamond category in 2026. The more accurate picture is a market where long-term mine supply is becoming structurally tighter, while short-term availability and pricing remain uneven across different types of diamonds.

Some stones are still relatively easy to source.

Others—especially larger diamonds, matched pairs, rare fancy colours, unusual vintage cuts, precise fancy shapes and narrowly defined premium specifications—may require more supplier depth and more time.

For retailers, the important question is therefore not:

“Are natural diamonds running out?”

It is:

“Which natural diamonds will become harder for my business to replace?”

That is a much more useful question.

For Dalila Diamonds, this creates a strong wholesale positioning opportunity. European jewellery retailers increasingly need more than a static list of available stones. They need access to an Antwerp sourcing network that can search multiple inventories, compare specifications, locate difficult requests and reduce dependence on whatever happens to be available from one supplier on one day.

Quick Answer: Is There Really a Natural Diamond Shortage in 2026?

Not across every category. The market is better described as structurally tightening over the long term while remaining uneven in the short term. Major mines such as Argyle have already closed, Diavik completed final production in March 2026, and De Beers has stated that global rough-diamond production is decreasing. At the same time, De Beers’ own first-half 2026 output was higher year over year, rough trading conditions remain difficult, and lower-value natural diamonds continue to face lab-grown competition. Retailers should therefore plan for selective scarcity rather than assume every natural diamond will become unavailable or automatically rise in price.

The most practical retail principle is:

do not panic-buy diamonds; identify the specifications that would be expensive, slow or difficult for your business to replace.

Why Natural Diamond Supply Is Becoming Structurally Tighter

Natural diamonds come from finite geological deposits.

A mine has:

a defined ore body,

a production profile,

operating costs,

changing grades,

and eventually an end of economic mine life.

Once an economically recoverable deposit is exhausted, production from that mine cannot simply be restarted indefinitely.

That is what happened at Argyle.

And in 2026, Diavik reached the same end-of-life stage.

The source notes that Rio Tinto confirmed Diavik’s final production in March 2026 after more than 150 million carats had been recovered over 23 years.

This matters because replacing a major diamond mine is not like opening another jewellery workshop.

New mines require:

exploration,

resource definition,

permitting,

financing,

infrastructure,

development,

and years of construction.

That makes natural-diamond supply structurally slow to expand.

Argyle Shows What Permanent Supply Removal Looks Like

Argyle is one of the clearest examples.

The source states that Argyle produced more than 865 million carats over its operating life before mining ended in November 2020 after economic reserves were exhausted.

Once a mine reaches that point, there is no operating decision that recreates the same geological source.

This becomes especially important when the mine was associated with unusual material.

Argyle was historically known for rare pink, red and other coloured diamonds.

Its closure therefore did not simply remove Carat volume.

It removed a historically important source of very specialised natural-diamond supply.

That gives retailers an important lesson:

Carats are not interchangeable.

Ten million carats from one mine can have a very different market effect from ten million carats of another production profile.

Diavik’s 2026 Closure Matters for Future Canadian Supply

Diavik is particularly relevant because its final production happened this year.

The source states that the mine produced predominantly white gem diamonds, together with some rare yellow diamonds, and delivered its final mine output in March 2026.

But this does not mean Diavik diamonds disappeared immediately from the market.

There will still be:

rough stock,

polished inventory,

dealer stock,

retailer inventory,

and secondary-market diamonds.

The important change is that no new mine production is entering the pipeline from Diavik.

That is the structural effect.

Mine Closure Does Not Mean Immediate Retail Shortage

EventImmediate EffectLonger-Term EffectMine closesExisting inventory remainsNo new production from that mineRough stock remainsManufacturing continuesPipeline gradually declinesRetail stock remainsCustomers can still buyReplacement depends on current/secondary supplyPremium categories remain availablePrices stay category-specificScarcity can become more visibleNew mine developsLittle immediate impactFuture supply may improve

Retailers should therefore avoid dramatic statements such as:

“Diavik closed, so Canadian diamonds are unavailable.”

That is inaccurate.

A more precise statement is:

“Diavik has stopped producing new rough diamonds, reducing one important source of future Canadian mine supply.”

De Beers Is Also Managing Production More Carefully

The 2026 supply picture is not driven only by mine exhaustion.

Producer strategy matters too.

The source states that De Beers reduced its 2026 production guidance to 21–26 million carats, down from an earlier higher range, in response to difficult rough-diamond trading conditions.

That means production can fall for two very different reasons:

geology

and

economics.

A mine can close permanently because the resource is exhausted.

Or a producer can deliberately reduce output because market demand is weak.

Retailers need to distinguish those situations.

H1 2026 Shows Why the Word “Shortage” Must Be Used Carefully

The source highlights a very important contradiction.

De Beers produced approximately 14.9 million carats in the first half of 2026, compared with about 10.2 million in the first half of 2025—a sharp year-on-year increase.

At first glance, that does not sound like a shortage.

But the comparison reflects unusually low production in the prior year and higher-grade ore being processed.

At the same time, De Beers expected maintenance and operational changes to reduce production rates later in 2026.

This is why jewellers should distinguish:

short-term production fluctuations

from

long-term mine-supply contraction.

This is much more accurate than saying simply:

“The market has a diamond shortage.”

Venetia Adds Another 2026 Supply Variable

The source notes that De Beers announced a proposed approximately two-year production pause at Venetia while continuing critical infrastructure work.

That is not the same as permanent closure.

But from a retailer’s perspective, the near-term effect still matters:

less active mine production can mean less fresh rough entering the market during that period.

Is Supply Tightening Because Demand Is Strong?

Not entirely.

This is another area where diamond-supply content often becomes too simplistic.

The source notes that rough-diamond trading conditions remained challenging during H1 2026, with macroeconomic and geopolitical uncertainty affecting the market. Lab-grown diamonds also continued to pressure lower-value natural-diamond categories.

At the same time, higher-value goods showed stronger pricing.

This creates a more segmented market.

Not every natural diamond behaves the same way.

The Market Is Becoming More Segmented

A lower-value commercial natural diamond facing strong lab-grown substitution may behave very differently from:

a 2.00 ct premium natural diamond,

a Fancy Pink,

an Old European Cut,

or a matched Pear pair.

This means scarcity should be analysed at specification level, not simply at market level.

Lower-Value vs Higher-Value Natural Diamonds

Category2026 Market DynamicLower-value commercial natural diamondsMore lab-grown pressureHigher-value natural diamondsMore resilient pricingLarge well-specified stonesMore sensitive to exact availabilityRare fancy coloursSpecialist scarcityMatched side stonesMatching creates supply difficultyUnusual fancy shapesAvailability variesGeneric small commercial goodsOften broader supply

The source specifically notes continued lab-grown pressure on lower-value natural diamonds while higher-value goods showed better pricing resilience.

Premium Demand Has Shown More Resilience

The source also notes stronger relative performance in higher-end natural-diamond demand, including better activity among US independent jewellers and more stable premium consumer demand.

That does not mean every premium diamond price will rise.

It means higher-value categories may behave differently from the value end of the market.

Why a 2-Carat Diamond Can Be Harder to Replace Than a 0.30-Carat Stone

Supply pressure often appears as replacement difficulty rather than total unavailability.

Imagine a retailer needs:

2.00–2.09 ct
Round Brilliant
G Colour
VS2
Excellent Cut
specific fluorescence preference
good proportions
recognised report

Now compare that with:

0.30–0.39 ct
Round Brilliant
G–H Colour
VS–SI Clarity

The second search creates a much larger acceptable inventory pool.

The first is much narrower.

That is why supply problems often show up first as:

“We cannot find the exact stone quickly.”

rather than:

“There are no diamonds.”

Replacement Difficulty Is a Better Metric Than Stock Quantity

Retailers often measure inventory by:

Carat weight,

number of stones,

or total value.

A more useful 2026 metric is:

replacement risk.

Ask:

If this diamond sells today, how difficult will it be to replace with something comparable next week?

That question separates ordinary stock from strategic inventory.

Replacement-Risk Matrix

Inventory CategoryReplacement Risk0.30 ct Round, broad gradesLow0.50 ct G VS2 ExcellentLow–Moderate0.90–0.99 ct premium RoundModerate1.00 ct D–F VS ExcellentModerate1.50 ct specific Oval ratioModerate–High2.00 ct G VS2 Excellent RoundHighMatched 0.40 ct Pear pairHighLarge Old European CutHighRare fancy-colour natural diamondVery High

This is much more commercially useful than trying to predict one universal shortage.

Sanctions Also Affect Accessible Supply

European diamond availability is shaped not only by geology.

Trade rules matter.

The source notes that EU restrictions on Russian-origin diamonds, including relevant goods processed through third countries, can affect:

trade routes,

documentation,

supplier eligibility,

and which diamonds can enter particular markets.

That does not necessarily reduce the number of diamonds physically existing in the world.

But it can reduce commercially accessible supply.

Physical Supply vs Commercial Supply vs Compliant Supply

Physical Supply

How many diamonds exist.

Commercial Supply

How many are currently being offered.

Compliant Supply

How many can be legally and documentarily purchased for the intended market.

Retail-Suitable Supply

How many match the required:

Carat,

Colour,

Clarity,

Cut,

shape,

certificate,

price,

and delivery deadline.

Retailers do not buy “global diamond production.”

They buy the last category.

Why Antwerp Matters More When Supply Becomes Fragmented

When availability is broad, sourcing can be transactional.

Search a database.

Compare prices.

Order the stone.

When availability becomes fragmented, networks matter more.

A strong Antwerp supplier can search across:

multiple dealers,

manufacturers,

owners,

polished inventories,

matched-pair specialists,

and bespoke sourcing channels.

This effectively expands the retailer’s inventory without requiring the retailer to physically own every stone.

Virtual Inventory Can Be More Valuable Than Overstocking

The wrong response to supply uncertainty is:

“Buy everything now.”

That creates:

working-capital pressure,

inventory-aging risk,

and potential exposure to categories whose demand later weakens.

A better strategy is:

selective owned stock + strong supplier access.

This helps preserve cash while keeping customer choice strong.

Carat Thresholds Should Not Be Treated as Absolute

Consumers often focus heavily on milestone weights such as:

0.50 ct,

0.70 ct,

1.00 ct,

1.50 ct,

and 2.00 ct.

When exact milestone stones become expensive or difficult to source, near-threshold options become useful.

Examples:

0.90–0.99 ct instead of exactly 1.00 ct,

1.40–1.49 ct instead of exactly 1.50 ct,

1.80–1.95 ct instead of insisting on 2.00 ct.

These can offer:

better availability,

better Cut,

or better value

while delivering very similar visual impact.

Example: 2.00 ct Request

Option A

2.01 ct
G
VS2
Excellent Cut
limited availability

Option B

1.91 ct
G
VS2
Excellent Cut
strong spread
better availability

Option C

2.04 ct
H
VS2
Excellent Cut
meets Carat target
slightly warmer Colour

A strong retailer explains the trade-offs instead of simply saying:

“We cannot get the exact diamond.”

Do Not Sacrifice Cut Just to Reach Carat

Supply constraints can create bad buying decisions.

A jeweller may accept:

weak proportions,

poor symmetry,

unwanted fluorescence,

or compromised appearance

just to reach an exact 2.00 ct threshold.

That is usually a mistake.

A beautifully cut 1.90 ct diamond can produce a better finished ring than a mediocre 2.00 ct stone.

The customer should buy the best jewellery outcome, not merely the largest number on the report.

Does Tight Supply Mean Prices Will Rise?

Not automatically.

This is one of the most important SEO corrections.

The source states that De Beers’ H1 2026 consolidated average realised price fell significantly, while its rough price index also declined, even though higher-value goods showed stronger pricing.

So the accurate conclusion is:

structurally tighter long-term supply does not automatically create immediate market-wide price increases.

Price still depends on:

category,

demand,

inventory,

producer strategy,

lab-grown substitution,

macroeconomics,

and retailer buying behaviour.

Scarcity Is Not the Same as Guaranteed Appreciation

Retailers should never say:

“Natural diamonds are guaranteed to rise because mines are closing.”

There is no responsible basis for that.

A stronger statement is:

“Natural-diamond mine supply is finite, and several important sources are closing or reducing production, which can make some categories harder to replace over time.”

That is factual without overpromising.

What About Lab-Grown Diamonds?

Lab-grown diamonds alter the market primarily through demand, not through geological natural-diamond supply.

The source notes that lab-grown diamonds continued to pressure lower-value natural-diamond categories in 2026.

This can further segment the market.

Customers focused primarily on:

maximum size for budget

may choose lab-grown.

Customers focused on:

natural origin,

geological rarity,

heritage,

and natural formation

may remain in the natural-diamond category.

Retailers should therefore discuss supply and demand together.

Scarcity Storytelling Must Stay Accurate

Avoid statements such as:

“Natural diamonds are disappearing.”

“Buy now before they run out.”

“Prices can only rise.”

“2-carat natural diamonds will soon be impossible to find.”

Those are pressure tactics.

A more accurate explanation is:

“Natural diamonds come from finite deposits, and some important mines have now ended production. That does not mean diamonds are disappearing, but some categories may increasingly depend on existing inventory and a smaller number of producing mines.”

Retail Inventory Strategy for 2026

Retailers should build stock around their own sales data.

Review the last 12–24 months.

Which stones sold repeatedly?

Which customer requests were lost because the diamond was unavailable?

Which categories took too long to replace?

Which stock has aged?

Which shapes are requested most often?

That gives the business a real sourcing strategy.

Example: Retailer A

Last 12 months:

18 sales of 0.40–0.60 ct Round

11 sales of 0.70–1.00 ct Round

7 Oval requests

2 Pear requests

1 stone above 1.50 ct

This retailer should not suddenly fill the safe with 2.00 ct diamonds because of shortage headlines.

It should:

strengthen core Round inventory,

maintain reliable Oval sourcing,

and use custom sourcing for large stones.

Example: Retailer B

Luxury private-client business:

8 sales above 1.50 ct

5 Emerald Cuts

4 stones above 2.00 ct

several D–F VS+ requests

This business has a completely different replacement-risk profile.

It may make sense to maintain more premium inventory or secure priority access through specialist suppliers.

There is no universal inventory formula.

Supplier Relationships Matter More When Exact Specifications Become Harder

A strong supplier relationship can reduce sourcing time because the supplier already understands:

your typical specifications,

price points,

certificate preferences,

customers,

turnaround time,

and buying behaviour.

This becomes more valuable as the market becomes fragmented.

Transactional Buying vs Strategic Sourcing

Transactional BuyingStrategic Supplier RelationshipSearch only when customer asksSupplier already knows common requirementsLowest price dominatesQuality, availability and documentation matterStart from zero every timeSupplier has historical knowledgeLimited reserve abilityBetter coordinationFrequent switchingConsistent communicationHarder bespoke matchingEasier custom sourcing

Efficiency matters more in a constrained market.

Build a Supplier Ladder

A strong retailer should consider:

a primary supplier,

a secondary supplier,

and specialist suppliers for difficult categories.

For example:

Primary — certified commercial natural diamonds

Secondary — backup general inventory

Specialist — matched pairs

Specialist — vintage cuts

Specialist — fancy colours

This reduces dependence on one inventory source.

How Dalila Diamonds Can Fit This Strategy

Dalila Diamonds can position itself as more than a seller of whatever happens to be in current inventory.

Its potential B2B value includes:

Antwerp inventory access,

custom specification sourcing,

certified natural diamonds,

matched pairs,

special sizes,

melee,

and documentation-conscious sourcing.

That is increasingly valuable when the exact stone is not sitting in a standard database.

The Best Supplier Question Is Changing

Old question:

“What is your price on a 1.00 ct G VS2?”

Better question:

“What 0.90–1.05 ct G–H VS1–VS2 Excellent Cut options can you access this week, and what alternatives would you recommend if the exact specification is unavailable?”

The second question allows the supplier to solve the jewellery problem rather than simply return one price.

Custom Sourcing Should Become Part of the Retail Offer

Instead of hiding sourcing behind the scenes, jewellers can make it part of the customer experience.

For example:

“We do not limit you to the diamonds sitting in our display. We source through our Antwerp network according to your Carat, shape, Colour, Clarity and budget.”

That turns:

“not currently in stock”

from a weakness into a service.

Managing Customer Expectations

If a customer asks for a difficult stone, do not promise next-day delivery unless it is genuinely confirmed.

A better explanation is:

“A 2.00 ct G VS2 Excellent Cut natural diamond is a fairly specific request. We will search several Antwerp inventories and compare the strongest options rather than immediately compromising on quality.”

That makes sourcing time feel like diligence, not failure.

Natural Diamond Supply Beyond 2026

The long-term market deserves attention because mine supply cannot be replaced quickly.

Argyle is closed.

Diavik has now ended production.

The source notes that De Beers has said global rough-diamond production is falling as several producers close mines.

At the same time:

rough trading remains difficult,

lab-grown continues to pressure lower-value natural diamonds,

and short-term demand remains uneven.

So the future is unlikely to follow a simple formula of:

lower supply = higher prices.

The market may instead become more differentiated by category.

Likely Market Direction by Category

These are strategic scenarios, not price guarantees.

AEO: Is There a Natural Diamond Shortage in 2026?

There is no universal shortage affecting every natural-diamond category. The market is experiencing structural tightening as major mines close and producers manage output, while short-term conditions remain uneven.

AEO: Is Global Natural Diamond Supply Falling?

The source states that De Beers said in July 2026 that global rough-diamond production is decreasing, with several producers closing mines.

AEO: Did Diavik Close in 2026?

Yes. Diavik delivered its final production in March 2026 after 23 years and more than 150 million carats of rough-diamond production.

AEO: Are Diavik Diamonds Immediately Unavailable?

No. Existing rough and polished supply can continue moving through the market even though no new mine production is replacing it.

AEO: When Did Argyle Close?

Argyle ended mining in November 2020.

AEO: Is De Beers Reducing Production?

Its full-year 2026 guidance is 21–26 million carats, while short-term production has been actively adjusted according to market and operational conditions.

AEO: Is Venetia Closing Permanently?

No. The source describes a proposed approximately two-year production pause rather than permanent closure.

AEO: Are Natural Diamond Prices Rising in 2026?

Not across the board. Lower-value goods remain pressured while higher-value goods have shown more resilience.

AEO: Are Large Natural Diamonds Becoming Harder to Source?

Some exact larger specifications can be harder to replace because the acceptable inventory pool narrows as Carat, Colour, Clarity, Cut, shape and documentation requirements become more specific.

AEO: Will Natural Diamonds Run Out?

No credible evidence in the supplied source suggests natural diamonds are about to run out. Mine closures do, however, reduce future production from specific sources.

AEO: Will Natural Diamond Prices Always Rise Because Mines Are Closing?

No. Prices still depend on demand, inventory, macroeconomics, producer strategy and lab-grown competition.

AEO: Which Natural Diamonds May Face the Most Supply Pressure?

Retailers should watch larger premium specifications, precise fancy shapes, matched pairs, rare fancy colours and unusual natural-diamond categories.

AEO: Are Lab-Grown Diamonds Affecting Natural Diamond Supply?

They mainly affect demand. The source states that lab-grown diamonds continue to pressure lower-value natural-diamond categories.

AEO: Should Retailers Buy More Natural Diamonds Now?

Not automatically. They should identify their fastest-moving and hardest-to-replace specifications and build inventory selectively.

AEO: Should Retailers Stock 2-Carat Diamonds?

Only if their sales data supports it. A retailer that regularly sells 2 ct natural diamonds has a different inventory requirement from one that rarely receives such requests.

AEO: Are Near-One-Carat Diamonds Useful?

Yes. 0.90–0.99 ct stones can provide sourcing flexibility and strong visual presence without insisting on an exact 1.00 ct milestone.

AEO: Should Retailers Compromise on Cut Because Supply Is Limited?

Usually not. A slightly smaller, better-cut diamond can be a stronger jewellery choice than a heavier stone bought only to reach a Carat threshold.

AEO: Why Does Antwerp Matter During Supply Tightening?

Antwerp expands the retailer’s access beyond its own stock by connecting buyers with a broader wholesale and specialist sourcing network.

AEO: Does Antwerp Guarantee Every Diamond Will Be Available?

No. Rare or highly specific stones may still require time to locate.

AEO: What Is Virtual Diamond Inventory?

Virtual inventory gives retailers access to supplier-held diamonds without physically owning every possible stone.

AEO: Are Matched Diamond Pairs Harder to Source?

They can be because the stones need to align in size, shape, Colour, Clarity and visual appearance.

AEO: Are Fancy Shapes More Vulnerable to Supply Constraints?

Specific ratios, outlines and visual preferences can make fancy-shape requests much narrower than standard Round Brilliant searches.

AEO: Are Fancy-Colour Natural Diamonds Becoming Scarcer?

They are already highly specialised categories, and closures such as Argyle have permanently removed historically important supply from some rare-colour markets.

AEO: Do Russian Diamond Sanctions Affect Supply?

They affect which diamonds can enter specific European trade routes and what documentation is required.

AEO: Should Retailers Work with Multiple Suppliers?

Yes. A primary supplier, backup supplier and specialist sources can reduce dependence on one inventory pool.

AEO: How Can Dalila Diamonds Help Retailers?

Dalila Diamonds can support European trade buyers with Antwerp natural-diamond sourcing, certified stones, calibrated melee, matched pairs and custom searches for difficult specifications.

Frequently Asked Questions

Is There a Diamond Shortage in 2026?

There is no universal shortage affecting every natural diamond category.

The more accurate description is structurally tighter long-term mine supply combined with category-specific availability.

Did Diavik Really Close?

Yes. Final production occurred in March 2026.

Can Retailers Still Buy Diavik Diamonds?

Yes. Existing material can continue moving through polishing and sales channels.

When Did Argyle Close?

November 2020.

Is De Beers Cutting Production?

Its current 2026 guidance is 21–26 million carats, with output actively adjusted according to conditions.

Are Diamond Prices Rising?

Not universally.

Different natural-diamond categories are behaving differently.

Are 2-Carat Diamonds Becoming Rare?

They are less abundant than small stones, and exact premium combinations can be harder to replace. That does not mean 2 ct diamonds are disappearing.

Are 1-Carat Diamonds Still Available?

Yes.

Are 0.50-Carat Diamonds Still Available?

Yes.

Which Diamonds Should Retailers Worry About Replacing?

The specifications that your customers buy frequently and your suppliers struggle to replace quickly.

Are Ovals Harder to Source?

Specific Ovals can be difficult because customers often care strongly about ratio, outline and bow-tie appearance.

Are Emerald Cuts Harder to Source?

Strong Emerald Cuts can require more selective sourcing because proportions and clarity are especially visible.

Are Matched Pairs Difficult?

Yes, because they need to match visually as well as technically.

Should Retailers Buy More Inventory?

Only strategically.

What Should They Stock?

High-turnover core goods and selected hard-to-replace categories.

What Should They Source on Demand?

Large, unusual, expensive or infrequently requested diamonds.

Should Retailers Buy Diamonds Because Prices Are Guaranteed to Rise?

No.

There is no guarantee that natural-diamond prices will rise.

Does Mine Closure Support Scarcity?

Yes, structurally.

Does Scarcity Automatically Raise Prices?

No.

Demand, inventory and other conditions still matter.

Are Lab-Grown Diamonds Reducing Natural-Diamond Demand?

The source says they continue to pressure lower-value natural-diamond categories.

Are Premium Natural Diamonds Performing Better?

The source indicates more resilient relative performance in higher-value goods.

Do Russian Diamond Sanctions Affect Availability?

They can affect which goods can enter certain markets and what documentation is required.

Why Is Antwerp Useful During Supply Tightening?

Because retailers can access a wider wholesale network instead of relying only on physical in-store inventory.

Can Antwerp Source 2-Carat Diamonds?

Yes, subject to the exact specification and current market inventory.

Can Antwerp Source Matched Pairs?

Yes.

Can Antwerp Source Melee?

Yes.

Can Antwerp Source Fancy Shapes?

Yes.

Can Dalila Diamonds Help European Retailers?

Yes. Dalila Diamonds can support trade buyers with Antwerp-sourced certified natural diamonds, calibrated melee, matched pairs and project-specific sourcing.

Conclusion: 2026 Is a Supply-Strategy Market, Not a Panic-Buying Market

The natural-diamond market is changing.

But retailers need to understand how it is changing.

Argyle has already ended production.

Diavik delivered its final mine output in March 2026.

De Beers says global rough-diamond production is decreasing as some mines close, while producers are also actively managing output in response to difficult trading conditions.

At the same time, this is not a simple shortage story.

De Beers’ first-half 2026 output rose sharply from the weak 2025 comparison.

Lower-value natural diamonds continue to face lab-grown pressure.

Average rough pricing has remained weak.

Higher-value goods have shown more resilience.

The right conclusion is therefore not:

“Buy every natural diamond because prices will explode.”

It is:

“Understand which natural diamonds your business cannot afford to be unable to source.”

For a bridal retailer, that may mean dependable 0.30–0.70 ct Round Brilliant inventory.

For a premium jeweller, it may mean stronger access to 1.00–2.00 ct certified natural diamonds.

For a bespoke atelier, it may mean reliable sourcing for Ovals, Pears, Emerald Cuts and matched pairs.

For an online brand, it may mean building strong virtual inventory instead of locking too much cash into physical stock.

For Dalila Diamonds, that creates a very clear B2B role.

One retailer may need:

a 0.50 ct Round tomorrow,

a 1.20 ct Oval next week,

a matched Pear pair for a bespoke ring,

or a 2.00 ct G VS2 Excellent Cut centre stone for a private client.

Some requests will be easy.

Some will take longer.

Some will require compromise.

Some will require searching several inventories before the right diamond appears.

That is exactly why sourcing capability becomes more valuable as mine supply becomes structurally tighter.

The future natural-diamond market will not be defined simply by whether diamonds exist. It will increasingly be defined by whether the right diamond—in the right quality, at the right price, with the right documentation—can be secured when the customer actually wants it.
