Engineering Behind the Stone
Some companies sell stone.
We solve what happens after the architect chooses it.
G STONE works at the point where architectural intent meets the realities of natural stone. We help define the right material, production method and technical solution before the project reaches the factory floor.
From drawings and detailing to fabrication, quality control and delivery coordination, we connect the decisions that determine whether a stone package works in reality — not only on paper.
Our role is simple: protect the architectural idea, understand the material and control the process required to make both work together.
We Know Stone From the Inside
Our experience was not built behind a desk.
It comes from quarries, factories, cutting lines, CNC machines, workshops, technical drawings, quality inspections, packing yards, containers and construction sites.
It comes from seeing what happens when the wrong block is selected.
When a beautiful drawing cannot be manufactured.
When tolerances are ignored.
When stone is processed correctly — and when it is not.
That accumulated experience allows us to see a project differently.
Before production begins, we are already thinking about the problems that may appear at the end.
And that is often what separates a successful stone package from an expensive mistake.
From Material to Architecture
Natural stone is never completely predictable.
Every block is different.
Every quarry behaves differently.
Every finish changes the material.
Every architectural detail creates its own technical challenges.
That is why we do not approach stone as a catalogue.
We approach it as a material that must be understood.
G STONE brings together:
Material sourcing and selection
Technical development
Precision fabrication
CNC processing
Architectural elements
Hand craftsmanship
Surface finishing
Mosaic and artistic stonework
Quality control
Packing and international logistics
Not because every project needs everything.
But because the person responsible for the stone must understand how all of it connects.
When Standard Is Not Enough
The most interesting projects rarely begin with a standard product.
They begin with a drawing.
A photograph.
A difficult detail.
A piece that has never been produced before.
A stone that has to perform in a way the architect imagined but the factory has not yet solved.
This is where G STONE is strongest.
We translate architectural intent into material reality.
Sometimes that means finding the right quarry.
Sometimes redesigning a detail so it can actually be fabricated.
Sometimes combining CNC precision with work that can only be done by hand.
Sometimes coordinating several producers, materials and countries around one project.
And sometimes the answer is simply knowing when something should not be produced the way it was originally drawn.
Experience Without Borders
G STONE operates internationally, connecting materials, production and projects across different markets.
Türkiye — and Denizli in particular — remains at the heart of our production network: a stone region we know not from brochures, but from daily work with its quarries, factories, technologies and craftsmen.
Beyond Türkiye, our work extends through an international network of materials, producers and specialists.
Because the right stone for a project is not always the stone closest to the factory.
The project defines the material.
The material defines the process.
Our job is to make the two work together.
The Human Factor
Behind G STONE is Yurii Tirabian, Founder & Managing Director.
His career has been built inside the natural-stone industry through an unusually broad range of real-world experience — sourcing, production, fabrication, international trade, technical coordination, quality control, logistics and project delivery.
That experience became the foundation of G STONE.
Not a company created around a catalogue.
Not a trading desk searching for the cheapest quotation.
But a business built around judgement.
Knowing what to select.
Knowing who can produce it.
Knowing what to control.
Knowing when something is wrong.
And knowing how to solve it.
Tuğba Solmaz
Logistics & Customs Operations Manager
Behind every smooth delivery there is someone who keeps a hundred details under control — and at G STONE, that person is Tuğba.
With her energy, warmth and constant smile, she manages one of the most demanding parts of our work: international logistics, customs procedures and export documentation. From coordinating shipments to making sure every document is exactly where it needs to be, Tuğba keeps our projects moving across borders.
She brings something equally important to the team — the human touch that makes even the most complicated working day a little easier.
Volkan Taşcıoğlu
Lead Architect & Technical Design Coordinator
Volkan is the architectural mind behind G STONE’s technical development. He works at the point where design intent meets the realities of natural stone, turning architectural concepts into details that can actually be produced, assembled and built.
From drawings and complex profiles to custom architectural elements, Volkan develops and coordinates the technical solutions that allow an idea to move confidently from screen to stone. He understands not only how something should look, but how it must be engineered, divided, fabricated and installed.
His role is to protect the architect’s original vision while making sure every detail is technically sound, production-ready and achievable in natural stone. In a material where every millimetre, joint and radius matters, Volkan brings precision, architectural judgement and a deep understanding of how design becomes reality.
Umut Altıntaş
Commercial & Finance Director
He oversees the commercial and financial operations of G STONE, bringing together financial control, commercial coordination and the day-to-day business processes behind our international projects.
Working closely with clients, suppliers and the G STONE team, he helps ensure that every project is commercially sound, financially controlled and executed on clear terms — from the first agreement through to completion.
His practical approach, attention to detail and understanding of international business make him a key part of the structure behind G STONE’s operations.
Who Comes to G STONE
Architects.
Developers.
Contractors.
Stone companies.
Designers.
People responsible for projects where the stone matters.
Sometimes they already know exactly what they need.
Sometimes they only know what they want the finished result to feel like.
Both are enough to start.
Because our role is not simply to answer:
“How much per square metre?”
Our role is to understand:
What are you trying to build — and what will it take to make it real?
Why G STONE
Because natural stone rewards knowledge and punishes assumptions.
Because beautiful material alone does not make a successful project.
Because precision without craftsmanship is not enough.
Because craftsmanship without engineering is not enough.
Because production without control is a risk.
And because complex projects need someone who sees more than one step at a time.
We connect vision, material, engineering and execution into one controlled process.
And when all four work together, stone stops being a limitation.
