Spain has a diamond market that needs to be understood in two very different ways.

On one side is the consumer jewellery market: engagement rings in Madrid, bespoke jewellery in Barcelona, warm yellow-gold designs in Valencia, family-run joyerías in Seville and fine-jewellery houses serving customers who buy diamonds for love, celebration, inheritance and personal milestones.

On the other side is an industrial diamond market, where diamonds are used for cutting, grinding, drilling, manufacturing and precision tooling.

Those two markets share the word diamond, but commercially they are completely different.

For Spanish jewellers, bridal specialists and fine-jewellery brands, the opportunity is not industrial demand. It is the market for gem-quality natural diamonds selected for beauty, design, certification and emotional value.

That distinction matters because jewellery content becomes weak when industrial statistics are mixed with consumer buying behaviour. A couple searching for an engagement ring in Madrid does not care how industrial diamonds perform inside cutting tools. A Barcelona designer building a limited fine-jewellery collection cares about shape, proportions, calibrated melee, certification and how the diamond interacts with the finished design.

Spain therefore needs its own jewellery sourcing strategy rather than generic European stock planning.

Spanish customers can respond particularly well to:

warm metals,

natural-diamond bridal jewellery,

fancy shapes,

colour,

personal design,

and pieces that feel expressive without losing quality.

For Dalila Diamonds, the opportunity is to support Spanish joyerías and fine-jewellery brands with Antwerp-sourced wholesale natural diamonds, including certified stones, fancy shapes, matched pairs, melee and bespoke diamond sourcing for bridal and design-led jewellery.

Quick Answer: What Should Spanish Jewellers Stock in 2026?

Spanish jewellers should build a balanced natural-diamond inventory around 0.30–1.00 ct bridal stones, Round Brilliants, Ovals, Pears, Emerald Cuts, Cushions, calibrated melee and selected matched pairs. Rather than buying only very high-colour diamonds, retailers should consider the final setting because G–H diamonds can work beautifully in yellow or rose gold when the Cut is strong. Larger diamonds, unusual fancy shapes and highly specific customer requests can often be sourced more efficiently through Antwerp instead of being permanently held in stock.

The practical strategy is simple:

stock the diamonds Spanish customers request repeatedly and custom source the rest.

Spain’s Diamond Market Has Two Completely Different Stories

The first step in understanding the Spanish diamond market is separating jewellery demand from industrial demand.

Industrial diamonds are bought primarily for their physical properties.

Hardness matters.

Wear resistance matters.

Technical consistency matters.

They may be used in:

cutting,

grinding,

drilling,

electronics,

automotive applications,

and other manufacturing processes.

A jewellery diamond is bought for a completely different reason.

Its value to the customer can depend on:

beauty,

rarity,

Carat,

Colour,

Clarity,

Cut,

shape,

certification,

design suitability,

and emotional meaning.

The source makes this separation explicitly: industrial diamonds and gem-quality natural diamonds represent different commercial worlds and should not be mixed when planning jewellery strategy.

This is especially important for SEO.

A page targeting:

diamond jewellery Spain

should not become filled with industrial-tool statistics simply because both markets use diamonds.

That dilutes search intent.

For a Spanish joyería, the commercial question is:

What type of natural-diamond jewellery does the customer actually want to wear?

The Madrid Bridal Market

Madrid is one of Spain’s strongest markets for bridal and fine jewellery.

Customers may be shopping for:

engagement rings,

wedding jewellery,

anniversary pieces,

luxury gifts,

or meaningful jewellery for major life moments.

The source describes Madrid buyers as customers who can value quality, tradition and presentation while still responding to jewellery that feels warmer and more expressive than some northern European markets.

That makes classic natural-diamond bridal jewellery important.

Round Brilliant solitaires should remain central.

But they should not be the entire offer.

A strong Madrid bridal range can also include:

Oval engagement rings,

three-stone rings,

diamond wedding bands,

Pear-shaped diamonds,

and refined pavé settings.

The important merchandising point is that Spanish bridal does not have to mean only a white-metal solitaire.

Yellow Gold Changes the Diamond Conversation

One of the strongest opportunities in Spain is warm metal.

Yellow gold can change how a natural diamond looks and therefore change which grades provide the best value.

Imagine two engagement-ring briefs.

Ring 1

Platinum solitaire
Minimal design
Very white visual appearance

Ring 2

18k yellow-gold engagement ring
Warm, elegant design
Slightly more Mediterranean visual character

The first design may justify prioritising a very high Colour grade.

The second may not.

A G or H Colour natural diamond with excellent Cut can look extremely attractive in yellow gold while potentially giving the customer more size or quality elsewhere in the specification.

The source makes exactly this point: retailers should not automatically buy only the highest Colour grades when the final jewellery will use warmer metal.

Example: Platinum vs Yellow-Gold Diamond Buying

FactorPlatinum SolitaireYellow-Gold RingColour emphasisHigherMore flexiblePossible core rangeD–GG–H often practicalCut importanceVery highVery highVisual styleCrisp, coolWarm, expressiveCustomer priorityWhiteness + brillianceOverall design + brillianceValue opportunityMore limitedGreater flexibility

The better sourcing question is therefore:

Where will the diamond be set?

Not simply:

What is the highest grade available?

Barcelona and the Catalan Design Influence

Barcelona creates a different opportunity.

The source describes it as a market strongly influenced by design culture, where customers may be more open to:

creative settings,

asymmetry,

coloured stones,

fancy shapes,

modern silhouettes,

and limited collections.

That matters because a Barcelona jewellery brand may need natural diamonds for much more than engagement rings.

It may use diamonds in:

self-purchase pieces,

designer earrings,

modern pendants,

coloured-gemstone jewellery,

limited-edition rings,

and artistic fine-jewellery collections.

For such businesses, the sourcing mix needs to be broader.

Fancy Shapes Can Be Particularly Useful in Barcelona

Shapes such as:

Oval,

Pear,

Marquise,

Emerald Cut,

and Cushion

give designers more flexibility than relying exclusively on Round Brilliant.

A Round Brilliant is visually familiar.

A Marquise can elongate a design.

An Emerald Cut can create architectural restraint.

A Pear can introduce asymmetry.

An Oval can feel contemporary without being excessively unconventional.

A Cushion can sit between classic and romantic.

This means shape itself becomes part of the creative vocabulary.

Small Diamonds Matter More Than Many Retailers Realise

Design-led jewellery is not always about one large centre stone.

Small diamonds can be essential.

They can create:

pavé,

hidden halos,

side accents,

earring details,

diamond-set shoulders,

and refined texture.

The source specifically warns Spanish retailers not to think only in terms of large centre stones because smaller diamonds often create the details that make design-led jewellery feel refined.

That makes calibrated melee a strategic stock category rather than an afterthought.

Spanish Jewellery and Warm Metals

Yellow gold has strong visual and cultural relevance in Iberian jewellery.

Rose gold can also work particularly well for romantic bridal designs.

White gold and platinum remain important for classic natural-diamond jewellery, but retailers should not assume that cool metals should dominate every collection.

The source directly links Spanish jewellery taste with warm metals and argues that diamond selection should reflect the setting rather than be made in isolation.

This creates a practical sourcing advantage.

A retailer does not have to force every customer into D–F Colour simply to demonstrate quality.

Instead, the jeweller can allocate budget intelligently.

For example:

Customer A

Budget: €4,500
Setting: Yellow gold
Priority: Noticeable centre stone

A G–H natural diamond with excellent Cut could potentially make more sense than paying heavily for D Colour.

Customer B

Budget: €8,500
Setting: Platinum solitaire
Priority: Premium purity and whiteness

Higher Colour may be more commercially appropriate.

The correct stone depends on the finished jewellery.

Fancy Yellow Diamonds and Spanish Colour Preference

Fancy Yellow natural diamonds can fit the Spanish market particularly well because their warmth naturally complements yellow gold.

The source positions Fancy Yellow diamonds as a potentially attractive category for clients wanting something different, particularly for:

right-hand rings,

anniversary jewellery,

statement pieces,

and bespoke commissions.

They do not need to replace white-diamond inventory.

They should sit beside it as a special category.

Fancy Colour Requires Accurate Disclosure

This is critical.

A naturally coloured diamond and a treated diamond are not the same product.

Retailers must distinguish them clearly.

For higher-value fancy-coloured diamonds, recognised grading reports can help customers understand:

whether colour is natural,

the colour grade,

the intensity,

and other characteristics.

The source explicitly warns that treated stones should never be presented as naturally fancy coloured.

This is both a trust issue and a professional retail standard.

What Spanish Jewellers Should Stock in 2026

The source recommends an inventory built around bridal, fine jewellery and bespoke demand rather than one narrow product category.

A practical 2026 inventory can include:

Round Brilliants for classic bridal,

Ovals and Pears for modern engagement jewellery,

Emerald Cuts for more restrained luxury,

Cushions for softer classic designs,

calibrated melee for pavé and halos,

and matched pairs for earrings and side-stone jewellery.

For everyday bridal, 0.30–1.00 ct natural diamonds can serve a broad customer range.

Larger stones should be selected according to real demand rather than stocked simply to create the impression of choice.

This provides enough visible choice without forcing the jeweller to own every possible stone.

Why Overstocking Large Diamonds Can Be a Mistake

Imagine a Spanish joyería buys:

five 1.50 ct Round Brilliants,

four 1.50 ct Ovals,

three 2.00 ct Emerald Cuts,

and several expensive fancy shapes.

That may look impressive in inventory.

But what if customers actually request:

0.50–0.90 ct stones,

yellow-gold settings,

smaller Pears,

and bespoke combinations?

Capital becomes trapped in slow-moving stock.

The source specifically recommends Antwerp custom sourcing for unusual requests rather than holding excessive slow-moving inventory.

A better strategy is:

stock commercial demand, source exceptional demand.

The Bridal Market Has Room to Grow

Spain may not always be as diamond-dominant in bridal as markets such as the UK or US.

That does not automatically make it a weaker opportunity.

It can create room for education.

The source notes that Spanish retailers can help customers understand natural diamond quality, certification and long-term value without forcing everyone into a standardised proposal-ring model.

That is particularly useful for independent joyerías.

One couple may choose:

a modest Round Brilliant in an exceptional setting.

Another may choose:

an Oval in yellow gold.

Another:

a coloured gemstone surrounded by natural-diamond accents.

Another:

an understated Emerald Cut.

There is no requirement for Spanish bridal to become visually uniform.

Natural Diamonds Should Be Sold as Part of the Whole Design

This is one of the most useful conclusions in the source.

Spanish customers may respond strongly to jewellery that feels:

personal,

warm,

beautifully made,

and intentional.

That means staff should not only discuss:

Carat,

Colour,

Clarity,

and Cut.

They should also explain:

how the stone works with the setting,

why the proportions suit the design,

how the metal affects visual colour,

and why that specific diamond was selected.

That creates more value than simply reading the grading report.

Madrid vs Barcelona vs Valencia vs Seville

Spain should not be treated as a completely identical retail market.

The source repeatedly uses different city examples because jewellery positioning can vary.

A useful segmentation is:

MarketLikely Commercial EmphasisMadridBridal, refined luxury, classic jewelleryBarcelonaDesign-led, fancy shapes, bespoke collectionsValenciaWarm metals, Mediterranean stylingSevilleFamily joyerías, warm gold, traditional/personal jewelleryWider Spanish premium marketBridal + bespoke + fine jewellery

This is not a rigid rule.

It is a merchandising framework.

A supplier can support all these markets while the retailer adapts the finished jewellery locally.

Certification and Spanish Customer Trust

Certification matters because it gives customers a structured way to understand the diamond.

The source identifies:

HRD,

GIA,

and IGI

as relevant grading reports for explaining:

Carat,

Colour,

Clarity,

Cut,

and other characteristics.

For higher-value natural diamonds, the source recommends treating certification as essential.

That does not mean every salesperson should simply hand the report to the customer.

The report should become part of the explanation.

Example: How to Explain Two Diamonds

Diamond A

0.80 ct
F Colour
VS1
Very Good Cut

Diamond B

0.75 ct
G Colour
VS2
Excellent Cut

A customer may assume Diamond A is automatically better.

But if Diamond B has better Cut and stronger visual performance, it may be the more attractive jewellery diamond.

A good jeweller explains:

“The first stone has slightly higher Colour and Clarity, but the second has stronger Cut and may appear more lively face-up. Because your setting is yellow gold, the small Colour difference may be less important than the Cut quality.”

That is actual expertise.

Certification Is Not the Same as Provenance

This distinction matters increasingly in 2026.

A grading report primarily describes the diamond.

Provenance and origin records address separate questions about sourcing.

The source states that Spanish jewellers should keep:

supplier invoices,

grading reports,

and origin-related documentation

together.

That creates a stronger customer and stock record.

EU Diamond-Origin Documentation in 2026

According to the supplied source, the EU requires a Due Diligence Statement on Diamond Origin for in-scope polished natural-diamond imports from 1 January 2026, and the article attributes this requirement to AWDC guidance.

For Spanish jewellers, the practical lesson is not to overwhelm customers with regulatory detail.

It is to ensure suppliers provide organised records.

The retailer should know where:

certificate,

invoice,

supplier record,

and available origin documentation

are stored.

Recommended Spanish Diamond Stock File

DocumentPurposeGrading reportDiamond characteristicsCertificate numberIdentifies the reportSupplier invoiceCommercial sourcePurchase dateTransaction historyInternal stock numberRetail trackingOrigin-related recordsSourcing supportCustomer invoiceFinal sale recordService historyFuture resizing/resetting

This becomes especially useful for:

insurance,

upgrades,

buyback,

resale,

and later customer questions.

Why Antwerp Supply Works for Spain

A Spanish jewellery store cannot hold every possible diamond.

Nor should it try.

The source uses a useful city-by-city example:

A Madrid joyería may need classic bridal stones.

A Barcelona designer may need unusual fancy shapes.

A Valencia retailer may require matched pairs.

A Seville jeweller may need melee for warm-gold pavé work.

One local shop cannot realistically keep all those combinations permanently available.

Antwerp sourcing provides another model.

The retailer maintains a focused inventory.

The supplier provides access to broader stock.

Antwerp as the Back-End Sourcing Network

A retailer can keep:

Round Brilliants,

a few Ovals,

common melee,

and typical bridal specifications.

Then Antwerp can support:

specific Emerald Cuts,

matched Pears,

unusual Carat ranges,

Fancy Yellow diamonds,

rare shapes,

or particular certificates.

This reduces capital pressure while maintaining customer choice.

Example: Barcelona Custom Request

Project: Contemporary three-stone ring
Centre: Natural Oval diamond
Carat: 1.00–1.20 ct
Colour: G–H
Clarity: VS2–SI1, eye-clean
Side stones: Small Pear-shaped natural diamonds
Metal: 18k yellow gold
Priority: Elegant outline, strong Cut, visually balanced pair
Certificate: Recognised grading report
Budget: Defined

This is exactly the kind of brief where custom sourcing can outperform generic inventory.

Example: Madrid Bridal Request

Shape: Round Brilliant
Carat: 0.70–0.85 ct
Colour: F–H
Clarity: VS2–SI1, eye-clean
Cut: Excellent preferred
Metal: Platinum
Certificate: GIA or HRD
Priority: Strong brilliance and face-up size

Example: Valencia Warm-Gold Request

Shape: Oval
Carat: 0.80–1.00 ct
Colour: G–H
Clarity: VS2
Metal: Yellow gold
Priority: Elegant length-to-width ratio
Customer goal: Warm, Mediterranean bridal aesthetic

The sourcing criteria change because the jewellery changes.

Avoid Mixing Industrial and Jewellery Messaging

This is one of the clearest SEO corrections the page needs.

Spain’s industrial diamond activity should not dominate a jewellery page.

The source explicitly says that customer-facing bridal pages should generally keep industrial-diamond discussion separate unless there is a specific educational reason to include it.

Why?

Because bridal customers care about:

beauty,

design,

certification,

value,

and emotional meaning.

Industrial buyers care about:

hardness,

tool performance,

wear,

and manufacturing.

The intent is completely different.

SEO Lesson: Keep Search Intent Clean

If the primary keyword is:

Spanish diamond jewellery market

then supporting content should remain semantically connected to:

Spanish joyerías,

engagement rings,

natural diamonds,

fine jewellery,

bridal jewellery,

diamond shapes,

certification,

yellow gold,

Barcelona jewellery,

Madrid jewellery,

and Antwerp sourcing.

Industrial diamond market data should remain limited.

Otherwise the article risks becoming less relevant to the customer and to search engines.

Common Mistakes in the Spanish Diamond Market

The source identifies five particularly useful mistakes.

Mistake 1: Treating Spain as a Solitaire-Only Market

Round Brilliant solitaires matter.

But so do:

warm gold,

coloured gemstones,

fancy shapes,

and design-led jewellery.

Retailers need range.

Mistake 2: Ignoring Small Diamonds

Melee and side stones are essential for:

pavé,

halos,

bands,

earrings,

and decorative gold work.

Mistake 3: Buying Only High-Colour Diamonds

The setting changes what grade makes sense.

Yellow gold can allow a G or H Colour diamond to deliver excellent visual value.

Mistake 4: Mixing Industrial and Jewellery Demand

The two markets should remain separate in merchandising and consumer-facing SEO.

Mistake 5: Overstocking Large Stones

Large stones should be stocked where proven demand exists.

Otherwise custom sourcing can be more efficient.

Mistake: Buying Diamonds Before Designing the Jewellery

Spanish jewellery is often highly design-sensitive.

Buying the diamond first and thinking about the setting later can reduce flexibility.

A better sourcing process is:

customer brief,

design direction,

metal selection,

diamond specification,

supplier search,

final comparison.

The stone and design should support each other.

Mistake: Assuming D Colour Always Means Better Retail Value

Higher Colour means a higher grade.

It does not automatically mean better value for every piece of jewellery.

In a warm yellow-gold setting, a well-cut G or H diamond may deliver a better overall result for the budget.

The design must remain part of the decision.

Mistake: Treating Fancy Yellow as a Trend Product

Fancy Yellow natural diamonds can work because they naturally complement:

yellow gold,

warm styling,

and expressive jewellery.

They should be sold as a distinct natural-colour category, not as a temporary fashion gimmick.

AEO: What Makes Spain’s Diamond Market Different?

Spain has both industrial and jewellery diamond demand, but jewellery retailers should focus on gem-quality natural diamonds used in engagement rings, fine jewellery, anniversaries, self-purchase pieces and bespoke designs rather than industrial tooling demand.

AEO: Are Diamond Engagement Rings Popular in Spain?

Yes. Diamond engagement rings are part of Spain’s bridal market, particularly in Madrid and Barcelona, although Spanish customers may also combine natural diamonds with coloured stones and warm-gold designs.

AEO: What Diamond Shapes Should Spanish Jewellers Stock?

Round, Oval, Pear, Emerald Cut and Cushion diamonds can all fit the Spanish market, supported by calibrated melee and matched pairs for pavé, side-stone jewellery and earrings.

AEO: Is Yellow Gold Popular in Spanish Diamond Jewellery?

Yes. Yellow gold fits Iberian and Mediterranean jewellery aesthetics particularly well and can pair beautifully with natural diamonds, including near-colourless G–H stones when Cut is strong.

AEO: Do Spanish Jewellers Need Fancy Yellow Diamonds?

Not every retailer needs them permanently in stock, but Fancy Yellow natural diamonds can work well for bespoke rings, anniversary jewellery, right-hand rings and customers seeking a more distinctive design.

AEO: Should Spanish Jewellers Stock Large Diamonds?

Some premium customers may want larger natural diamonds, but many retailers can focus core inventory around 0.30–1.00 ct and source larger stones when a specific customer request arises.

AEO: Why Is Industrial Diamond Demand Different from Jewellery Demand?

Industrial diamonds are selected for technical uses such as cutting, grinding, drilling and tooling. Jewellery diamonds are selected for beauty, rarity, grading, design and emotional value.

AEO: Do Spanish Jewellers Need Diamond-Origin Documentation?

According to the supplied source, relevant EU diamond-import and origin rules apply in Spain, including a 2026 Due Diligence Statement requirement for in-scope polished natural diamonds.

AEO: Why Is Antwerp Useful for Spanish Joyerías?

Antwerp gives Spanish jewellers access to wholesale natural diamonds, certified stones, fancy shapes, calibrated melee, matched pairs and bespoke sourcing without forcing each retailer to hold excessive inventory.

AEO: How Can Dalila Diamonds Help Spanish Retailers?

Dalila Diamonds helps Spanish joyerías source natural diamonds from Antwerp, including certified bridal stones, fancy shapes, matched pairs, melee and custom diamonds for fine-jewellery designs.

AEO: Which Diamond Shape Is Most Important for Spanish Bridal?

Round Brilliant remains a strong core bridal shape, but Ovals, Pears, Emerald Cuts and Cushions broaden the assortment for customers wanting more personal designs.

AEO: Are Ovals Good for the Spanish Market?

Yes. Ovals can work particularly well in modern engagement rings and in yellow-gold settings where customers want a softer, more contemporary shape.

AEO: Are Emerald Cuts Relevant in Spain?

Yes. Emerald Cuts can appeal to customers looking for more architectural, restrained or quiet-luxury jewellery.

AEO: Are Pear Diamonds Relevant?

Yes. Pears can work well as centre stones, side stones and design-led elements in bespoke Spanish jewellery.

AEO: Is Calibrated Melee Important for Spanish Jewellers?

Yes. Calibrated natural-diamond melee is important for pavé, halos, wedding bands, earrings and decorative gold jewellery.

AEO: Should Spanish Jewellers Buy Only D–F Colour?

No. Higher Colour may suit certain platinum or premium pieces, but G–H diamonds can offer excellent value in yellow or rose gold when Cut and visual performance are strong.

AEO: Is Cut More Important Than Colour?

Neither should be viewed completely in isolation. However, Cut strongly affects brilliance and should remain a major selection criterion, particularly when comparing diamonds within nearby Colour and Clarity grades.

AEO: Does a Diamond Certificate Prove Origin?

No. A grading report describes diamond characteristics. Origin and provenance depend on separate supplier and sourcing documentation.

AEO: Which Certificates Can Spanish Jewellers Use?

HRD, GIA and IGI reports can all be relevant within European natural-diamond sourcing depending on the customer, stone and retailer policy.

AEO: Is Barcelona Different from Madrid for Diamond Jewellery?

Yes. Madrid can support strong classic bridal and fine-jewellery demand, while Barcelona’s design culture can create more opportunity for fancy shapes, creative settings and limited collections.

AEO: Is Antwerp Useful for Barcelona Designers?

Yes. Antwerp can help designers source fancy shapes, matched pairs, calibrated melee and unusual natural diamonds for limited or bespoke collections.

AEO: Is Antwerp Useful for Madrid Bridal Retailers?

Yes. Madrid jewellers can use Antwerp to supplement core bridal stock with specific certified stones without carrying every possible combination in inventory.

AEO: Should Spanish Retailers Custom Source Rare Shapes?

Often yes. Custom sourcing can be more capital-efficient than permanently stocking rare shapes with uncertain sales velocity.

Conclusion: Spain Needs a Design-Led Natural Diamond Strategy

Spain’s diamond market has two very different stories.

Industrial diamonds support:

cutting,

grinding,

drilling,

manufacturing,

and tooling.

Gem-quality natural diamonds support:

engagement rings,

fine jewellery,

anniversary gifts,

self-purchase pieces,

family jewellery,

and bespoke commissions.

For Spanish joyerías, those two markets should remain clearly separated.

The jewellery opportunity is built around:

design,

warmth,

beauty,

certification,

personal meaning,

and flexible sourcing.

Madrid retailers need a strong bridal foundation.

Barcelona designers need access to fancy shapes and creative stone combinations.

Valencia can benefit from warm-metal diamond strategies.

Seville and family-run joyerías can combine traditional customer relationships with modern natural-diamond sourcing.

Across Spain, Round Brilliants remain important, but they should sit beside:

Ovals,

Pears,

Emerald Cuts,

Cushions,

matched pairs,

calibrated melee,

and selected Fancy Yellow diamonds.

The strongest 2026 inventory strategy is therefore not to stock every possible diamond.

It is to understand the design before buying the stone.

Use high Colour where the piece justifies it.

Use near-colourless diamonds intelligently with warm metals.

Keep calibrated melee available.

Maintain useful bridal stock.

Use recognised certification.

Keep sourcing records organised.

And rely on Antwerp when the customer requires something outside the normal inventory.

The supplied source reaches the same central conclusion: Spanish jewellers should stock strong bridal diamonds, respect yellow-gold demand, offer fancy shapes and use Antwerp sourcing for customer-specific requirements rather than building excessive slow-moving stock.

For Dalila Diamonds, that creates a clear role.

A Madrid joyería may need a 0.80 ct Excellent Cut Round Brilliant.

A Barcelona designer may need a Marquise and calibrated melee for a limited collection.

A Valencia retailer may need an Oval that works beautifully in yellow gold.

A Seville jeweller may need matched Pear side stones for a family client’s bespoke ring.

The designs change.

The sourcing principle remains the same:

the best diamond for the Spanish market is not simply the highest grade on paper — it is the natural diamond whose shape, quality, certification and visual character work best with the jewellery the customer actually wants to wear.
