About
We buy at the block, not from a yard.
Petrarra is a Denizli natural stone programme — marble, travertine and onyx — built around one commitment: the block is chosen before it is cut, and the number on it survives all the way to your packing list.
Stone is not a design anyone owns. Material has been coming out of the Denizli basin for two thousand years — the Romans built Hierapolis out of it — and every catalogue in this trade shows the same warm beige floor and the same white marble. What differs is invisible in a photograph: which block the material came off, whether anyone wrote the number down, whether the tile was measured after calibration or before, and whether the person selling it can still get you the same stone next season.
We work from Denizli, roughly three hours from İzmir, inside the customs union. A European importer gets a container in three to four weeks against the eight to ten a Far East order takes, and a mid-project top-up is a real option rather than a next-year problem. That matters more in stone than in almost any other material, because the top-up has to match what is already on the floor.
The range is deliberately narrow — marble, travertine and onyx, in the formats a stone buyer actually orders. We are not the supplier for an importer who wants one purchase order to cover an entire project. We are the supplier for the one who has been burned on colour continuity and wants that part fixed.

About
We buy at the block, not from a yard.
Choose the block first
Material is selected and reserved at source before it is sawn, and numbered from that moment. When a colour drifts there is one number to look up and one company to answer for it.
Publish the reading
Absorption, tolerance, frost cycles and abrasion go out with the order and are referenced by block number. A number that can be checked is worth more than an adjective that cannot.
Say what we do not control
We do not own quarries and we do not claim to. We select block, we control the cut sequence and the calibration, and we inspect before loading. A supplier who claims to quarry fourteen materials in one district is describing a warehouse.
Hold the date
Twenty-one days ex-works, and a short order is declared short rather than topped up from something that looks close enough.
03
Compliance
The document set an importer opens first.
Natural stone placed on the EU market is sold against a harmonised standard and a Declaration of Performance, and the values in it belong to a specific material from a specific quarry. These are the standards your specification and your DoP will be written against; the test reports for your material go out with the order.
