How do you find the right natural stone for a project?

And why the shortest procurement route is not automatically the smartest decision.

A guide for professionals shaping tomorrow’s spaces – with natural stone.

Some time ago, a client said to me:

“We’ll order the material ourselves. I know someone who knows someone. That will surely make it cheaper.”

Does that sound familiar?

At first, the thought is understandable. Anyone planning a high-end project naturally looks at budgets, offers, supply routes and potential savings. Especially with natural stone, the idea quickly arises: the closer you get to the source, the better it will automatically be. Or at least cheaper.

That sentence stayed with me. From the client’s perspective, it’s absolutely understandable. But it also reveals the exact point: natural stone is often first treated as a procurement question, and only much later as a material decision.

Because the real question is not only: “Where can we get the stone for less?”

The more important question is: “Does that also lead to a better material decision?”

In high-end projects, natural stone is often discussed through price.

What does it cost per square metre? Where is the stone located? Does it come from a dealer, an importer or directly from the quarry? Is there a cheaper alternative? Can intermediate steps be avoided?

These are legitimate questions. But they do not go far enough.

Because the price of a natural stone slab is only one part of the decision. The real value does not arise from procurement alone, but from the question of whether this particular stone is truly right for this particular project.

For the location. For the use. For the light. For the fabrication. For the maintenance. For the client’s expectations. For many years of operation.

An expensive stone can be wrong. A more affordable stone can be right. A directly sourced stone can be excellent. And a directly sourced stone can still be a poor decision.

Direct does not automatically mean suitable. Direct does not automatically mean verified. Direct does not automatically mean project-safe. And direct does not automatically mean cheaper.

At first, it only means one thing: the procurement route is shorter. That can be an advantage. But only if someone is able to assess what is actually being selected there.

What quality does the block have? How stable is the selection? How strong is the veining? How will the material behave in the intended application? Which surface finish makes sense? Which formats are realistic? Which reserves are needed? How reliable is the possibility of reordering? Who takes responsibility if the slab later does not match the planning, the use or the client’s expectations?

This is where the difference between procurement and material decision begins.

A good dealer can be highly valuable in this process.

They know materials, availability, selections, stock levels and often the specific characteristics of certain quarries. They can secure quality, provide samples, organise supply chains and play an important role in the event of claims or complaints.

Especially because there are thousands of quarries around the world, orientation matters.

Every quarry has its own strengths, limitations, qualities, selections, lead times and fabrication possibilities. No planner, no dealer and no direct buyer knows the entire market completely.

That is why the direct route to the quarry is not automatically more objective – and not automatically more economical.

Anyone buying directly ultimately also makes decisions within their own network: from the quarries they know, trust, have had good experiences with or feel well supported by both professionally and organisationally.

That can make a lot of sense.

But it is not automatically the best solution for every project.

Because economically, “direct” is not always the same as “better”. A dealer who regularly purchases larger quantities may obtain better conditions, more stable delivery commitments or more reliable reservations for certain materials than a single project that perhaps requires only 500 square metres.

In addition, there are stock availability, pre-selection, access to samples, claims handling, the ability to reorder and experience with specific qualities.

So the direct route may be shorter.

But shorter does not automatically mean cheaper, safer or smarter.

That is exactly why the question is not dealer or quarry.

It is the quality of the decision.

A dealer is not automatically independent. A direct buyer is not automatically neutral. A short procurement route is not automatically a better material decision.

What matters is whether someone considers the project, the intended use, the design ambition, the technical suitability and the later responsibility together.

Because natural stone does not need a romantic procurement story.

Natural stone needs decision security.

Luxury in natural stone is not created by choosing the most expensive stone. Nor is it created by buying as directly as possible.

Luxury emerges when aesthetics, material quality, technical suitability, execution and use are considered together.

The right stone is not always the most spectacular. Not always the most expensive. Not always the rarest. Not always the one sourced through the most direct route.

The right stone is the one that works permanently within the project – aesthetically, technically and economically.

Especially in high-end real estate, hotels, private residences or representative spaces, the issue is therefore not only procurement. It is responsibility.

Because natural stone is not an interchangeable surface product.

It is a natural material with character, variation, limitations and possibilities. Anyone who evaluates it only by price, origin or availability does not see the full picture.

And this is precisely where projects become expensive.

Not always at the time of purchase. Often only later.

When the surface finish does not match the use. When the selection does not match the architectural ambition. When the slabs in place look different than expected. When cleaning and maintenance were not taken into account. When reordering becomes difficult. When technical requirements only become apparent on the construction site.

Then the stone was not necessarily too expensive.

Then the decision was made too cheaply.

Natural stone is an investment decision. Not a pure procurement item.

The best procurement route is therefore not automatically the shortest.

It is the one that leads to the right material decision.

And that is why the crucial question should not be:

“Where can we get the stone at the lowest price?”

The question should be:

“Who will help us make the right material decision – before it becomes expensive?”

Answering this question early on often saves not only money, but also time, coordination, complaints and later compromises.

That is exactly where the real value of a good natural stone decision lies.

April 2026

Natural stone is getting a passport.

And with it, something long taken for granted begins to change:

material decisions become traceable.

A guide for professionals shaping tomorrow’s spaces – with natural stone.

The conversations I am having at the moment tend to circle around the same themes.
Prices. Supply chains. Uncertainty.
That is understandable, because this is where the most visible changes are currently taking place.
And yet, there is a growing sense that the real shift is happening somewhere else.
More quietly. Less tangible. But with a far more lasting impact on projects.

With the Digital Product Passport, this shift begins to take shape.

What initially appears to be just another technical tool reveals itself, upon closer examination, as a structural intervention in how materials will be evaluated and used in the future.

A natural stone product will no longer be described or positioned purely through references.

It will be assigned a digital identity, bringing together information on origin, processing, transport, performance and use.

This information is not intended as an addition.

It is gradually becoming the basis for decision-making.

In practice, this represents a change that feels subtle at first – and is therefore easy to underestimate.

Until now, many material decisions have been based on experience, trust and design intuition. Samples, references and personal judgement play a central role. This will not disappear.

But it will be complemented by a layer that is far more concrete and verifiable.

The question of whether a material looks right or fits the concept will no longer be sufficient.

What will matter is whether that decision can be understood and justified – even at a later stage, when questions of use, maintenance or even dismantling arise.

This is precisely where the relevance for projects begins.

A digitally documented material does not only influence selection.

It reshapes planning and long-term use.

Specifications will need to become more precise, because information is no longer optional.

Responsibilities along the supply chain will become clearer, because it will be evident where a material originates and who provides which data.

At the same time, operators gain a new basis for understanding and evaluating materials during use. Maintenance, care and lifespan can no longer rely solely on experience, but increasingly on documented properties.

The Digital Product Passport is not an isolated industry topic.

It is part of a broader regulatory development within the European Union, driven by the European Commission as part of the Ecodesign framework and the Circular Economy strategy. The aim is to make products more transparent across their entire life cycle and therefore more sustainable in their evaluation.

Implementation will take place gradually, across different product categories. Construction materials are clearly in focus, even though not all details for natural stone have been fully defined yet.

One point is often misunderstood:

The Digital Product Passport does not apply only to products manufactured within the EU.

It applies to all products placed on the EU market. This means that international supply chains are directly affected. A natural stone from India used in Europe will be subject to the same requirements as material from Italy or Germany.

In this way, a European regulation becomes a globally relevant system.

Responsibility for providing data does not lie with a single party.

It is distributed across the entire value chain. Producers, processors, importers and, in part, distributors will all be required to provide structured information. For planners and clients, this means that such information should not only be available, but actively requested.

What emerges from this is a shift that has less to do with the material itself and more with how we handle it.
A natural stone can be technically excellent and aesthetically convincing.
If its origin is not clearly documented, if its processing is not traceable, or if its properties are not properly classified, it loses relevance in the decision-making process.
Not because it is inferior,
but because it is less tangible.

In practice, this gap is already visible today.

Materials are often selected because they are available, because they look right, or because they fit within a certain budget framework. A complete understanding of origin, processing and long-term performance is often only partial.

This still works within the current system.

The question is: for how much longer.

The Digital Product Passport does not change this situation abruptly, but it does so consistently.

It shifts the focus away from pure material impact towards a combination of impact and traceability.

And that is where its real significance lies.

The key question is not whether this system will come, or how exactly it will be implemented in detail.

What matters is how early we begin to think about material decisions within this broader context.

Natural stone has always been an honest material.

Perhaps that is precisely where the opportunity lies.

What exists can be made visible.

It simply requires consistency.

Natural stone is never neutral What Mies, Loos and Zaha Hadid understood about natural stone

A guide for everyone shaping the future with natural stone

This newsletter is not a retrospective on great names. It is a look at an uncomfortable truth: natural stone reveals how seriously a design really means it.

Good architecture is not always recognized first by its form.

Sometimes, it is recognized by the way
it handles material.

Natural stone, in particular, is an unforgiving test.

It cannot be staged into meaning.
It cannot be talked into substance.
It brings weight into a space.
Time.
Resistance.
And a truth many projects would rather avoid:

Material is never just surface.

Anyone working with natural stone is therefore deciding not only about appearance,
but about attitude.

And perhaps that is exactly why stone continues to occupy such a singular place in architecture.

Not because it is expensive.
Not because it looks prestigious.
Not because it photographs well.

But because it reveals something.

It shows whether a design has discipline.
Whether it can carry dignity.
Whether its form has substance.
Or whether, in the end, nothing remains but surface.

Three architects demonstrate this in radically different ways:
Mies van der Rohe.
Adolf Loos.
Zaha Hadid.

Three attitudes.
Three languages.
Three completely different answers to the same question:

What happens when natural stone is allowed to become more than a finish?

Mies van der Rohe – Stone as discipline

With Mies van der Rohe, stone is never an accessory.

It orders.

In the Barcelona Pavilion, natural stone does not appear as a decorative claim, but as a calm and precisely placed presence. Travertine, marble and onyx do not occupy the space to demand attention. They structure it. They steady it. They create that quiet authority which only emerges when material is given room to speak without interruption.

That may be Mies’s real strength.

He does not show how to make stone spectacular.
He shows how to let it work in silence.

No overstatement.
No decorative pathos.
No fear of surface.

Only material.
Light.
Proportion.
Jointing.

And the discipline to remove everything that interferes.

That remains radical to this day.

Because many projects want natural stone to become an event immediately.
Mies does something more difficult:

He allows it to feel inevitable.

And that is precisely what makes it powerful.

Perhaps this is the first uncomfortable lesson of the material:
not every high-quality stone needs a spectacular detail.
Sometimes it only needs a design strong enough not to comment on it constantly.

Adolf Loos -Stone as dignity

With Adolf Loos, the question of material becomes sharper.

Loos was not against impact.
He was against deception.

He mistrusted everything that merely simulated meaning.
Everything that decorated where substance was missing.
Everything that replaced material instead of taking it seriously.

That is exactly why his use of natural stone still matters.

At the Looshaus in Vienna, this becomes unmistakably clear: marble below, restraint above. No decorative excess, no pleasing gesture, no façade seeking approval. Instead, a base of material dignity, and above it, an almost provocative plainness.

This attitude becomes even more concentrated in the Loosbar.

Within the smallest of spaces, it achieves what many large-scale projects fail to reach: atmosphere through consequence. Marble columns. Stone flooring. Onyx. Mirrors. Wood. Density. Tension. No element is there by accident. Nothing is trying to look luxurious.

It is luxurious because material, space and proportion belong together.

And this is precisely the point many still miss:

Luxury is not decoration.
Luxury is consequence.

Not one more gesture.
Not one more effect.
Not one more supposedly noble surface that, in truth, only conceals insecurity.

But the decision to take real material so seriously
that nothing cheap can be added to it anymore.

That is uncomfortable.
But true:

Expensive stone does not heal weak design

Zaha Hadid – Stone as movement

And then there is Zaha Hadid.

Here, stone does not become still.
Here, it begins to move.

Or at least, it seems to.

Zaha Hadid did not treat natural stone as historical weight, but as a material that could be translated into a new spatial language. Not rigid. Not merely dignified. Not simply monumental. But fluid, transformative, almost sculptural.

That is exactly where her relevance lies.

Because she contradicts an old misunderstanding:
that natural stone must always mean calm, heaviness and tradition.

No.

It can also carry tension.
It can generate dynamism.
It can articulate the future.

In projects such as Stone Towers, this becomes visible. Stone does not appear as a nostalgic reference, but as an active surface whose identity shifts constantly through relief, depth, light and shadow. In the studio’s sculptural work as well, stone becomes more than mass. It becomes movement held in condensed form.

That sounds poetic.

But technically, it is brutally demanding.

Because the freer the form,
the more uncompromising the understanding behind it must be.

Planning.
Fabrication.
Tolerances.
Junctions.
Light.
Execution.

When that precision is missing, vision turns into scenery very quickly.

And perhaps that is the second uncomfortable truth:
not every expressive stone gesture is progress.
Some of it is simply poorly controlled effect.

What it means now

Mies, Loos and Zaha are not interesting because their names signal cultural literacy.

They matter because they understood something fundamental:

Natural stone is not an interchangeable finish.

With Mies, it orders space.
With Loos, it carries dignity.
With Zaha, it sets form in motion.

But for contemporary projects, the her real question lies elsewhere.

Not: Which stone looks good?
But: Is the material truly being thought through?

In the selection.
In the detail.
In the build-up.
In the jointing.
In the light.
In the use.
In maintenance.
In long-term value retention.

That is exactly where many natural stone projects still fail today.

Not because of the stone itself.
But because of the separation between design and reality.
Between concept and operation.
Between surface and system.

A material can look outstanding as a sample
and fail in everyday use.

Not because natural stone is problematic.
But because no one took responsibility for thinking selection, technical detailing, execution and future use together.

And this, in my view, is where real quality begins.

Not with the beautiful slab.
But with the question of whether a project wants merely to show the stone
or actually understand it.

In high-end interiors, existing buildings, hospitality environments and representative properties, this becomes visible very quickly. That is where it is decided whether natural stone merely creates an impression – or carries quality over time.

Closing thought

Anyone who wants to integrate natural stone convincingly today needs more than material sensitivity.

They need an understanding of how selection, detailing, execution and future use interact.

Because that is exactly where it is decided whether stone merely creates an impression – or carries lasting quality.

Because in the end, natural stone does not only shape spaces.
It reveals the standard behind them.

The White Stone Paradox

“Let’s just go with white”

That’s the sentence that sounds like safety in meetings and often turns into follow-up costs on site.

Because white isn’t a color. White is an amplifier. It amplifies light, joint patterns, and every decision you wanted to postpone. And that’s exactly why a white natural stone is never just a material, it’s an operating system. (You can ignore it. But it won’t ignore you back.)

The Truth

White natural stones are bought as neutrality. In reality, they work like a microphone. They make audible what used to be only quietly wrong.

Raking light reveals flatness or the lack of it. Acids make polished surfaces more honest than we’d like (think: etching). And real-life operation (people, cleaning routines, time) turns design into either elegance or patina with excuses.

The most common mistake isn’t choosing the wrong stone. The most common mistake is treating white like a decorative color.

The Decision

At the core, you have three paths:

Just white. Quickly decided. Later explained.
White like in the rendering. Works… until daylight, real use, and real cleaning products move in.
White as a system. You define use, finish, substrate, joints, and maintenance upfront and white feels like luxury instead of risk.

Luxury is rarely expensive. Most of the time, it simply means: thinking early instead of paying later.

The Discovery

White isn’t one category. It’s three different games, for example:

THASSOS Radical Purity

Known for its bright, sparkling whiteness and strong light reflection. If you choose Thassos, you choose: maximum calm, maximum visibility of substrate and joints. A surface that reads more like “light” than “pattern”. Risk note: Thassos doesn’t forgive. It documents. Very neatly.

VOLAKAS Controlled Movement

Volakas is a Greek (dolomitic) marble with a white background and variable veining. If you choose Volakas, you choose: white with elegance, without sterility; a material that rewards selection.

STATUARIO (Carrara) Iconic Drama

Statuario is considered one of the most exclusive white marbles. If you choose Statuario, you choose a statement. Real talk: Statuario without an approval process is like a Porsche without brakes.

How It’s Done

This is how white becomes sovereign instead of sensitive:

Finish: Polished = maximum brilliance; Honed/brushed = better real-life performance.
Substrate: Flatness isn’t technical, it’s visual.
Joints: White turns joints into either elegance or noise.
Maintenance: Etching isn’t dirt, it’s chemistry. Plan for it.

White Stone Decision Matrix

How intense is the usage?
How much raking light hits the surface?
How much aging can the surface tolerate?
Is there a maintenance concept?
Are selection and approval planned?

The Uncomfortable Truth

“White stones are sensitive” is often just a polite way of saying:

“We planned them wrong.” White doesn’t fail because it isn’t beautiful. White fails because structure was missing. And in high-end projects, structure is not optional.

It’s the difference between luxury and complaints.

Naturstein Marmor R&R Raddato Projektmanagement GmbH

Is your design made for people or for likes?

You’re not working on rooms.

You’re working on states of being. And you know the situation:

The space is finished. Budget was not the issue. Natural stone, fixtures, wood, textiles, everything top shelf. The client stands there, looks around, nods politely… and emotionally, very little happens. No exhale. No “I want to stay here.” No warmth. And you can sense it: without being able to explain it, the client quietly takes a step back – internally.

Then comes the sentence that keeps you reliably alert: “It’s beautiful. But something doesn’t feel right.”

And that’s usually when the familiar rescue plan begins: a shade warmer, one more rug, a different textile, a new object – as if a missing feeling could be filled like a styling gap.

And that’s exactly why this uncomfortable question is worth asking:

Would you still choose this design the same way if no one could photograph it, post it, or rate it? If it were only about the experience. About being there. About how the space feels in the body. About the nervous system.

Many high-end interiors don’t fail because of budget. They fail because of a quiet mix-up:

You build value – and expect warmth.
You build perfection – and hope for closeness.

The conflict: when “exclusive” doesn’t automatically mean “inviting”

You know these spaces: everything is perfect on paper. Rare materials, big names, flawless execution – and still, something is missing. That “yes.” That “I can be here.”

Because people don’t experience spaces like catalogs. They scan unconsciously: Am I safe here? Can I move? Can I leave traces? Can I breathe?

And this is exactly where natural stone becomes interesting – not as a prestige material, but as a psychological tool. Because natural stone carries something many interiors lack: truth. It isn’t perfect – and that’s precisely why it can feel credible.

The bet no one expects

The real bet is: admiration or belonging?

Admiration works through distance. Through “please don’t touch.” Belonging works through permission. Through “you can relax.” Through a surface that allows closeness.

The crash: when perfection eats warmth

Perfection looks confident in pictures. In real life it can trigger something else: vigilance. A room that allows no mistakes in every detail often does the same to its occupants: it allows no mistakes.

Why touch plays the hidden lead role

The body is faster than the mind. The same stone can show up like two completely different personalities. One says: “I’m gala.” The other says: “I’m home.”

Is your design a place where people are allowed to live, or a place where they have to behave? Sometimes you need a material that quietly says: “You’re allowed to be here.”

The thing about curves

Curves aren’t just form. They’re a message. They remove sharpness from a space.

A sharp edge says: “Stop.”
A radius, a soft transition says: “Come closer.”

And suddenly it makes sense why some rooms don’t feel warm…
