Questions from specifiers

How do I verify it is genuine Portoro?

We provide quarry-of-origin documentation. The signature gold veining and density (~2.8 g/cm3) distinguish authentic Portoro from Chinese or Iranian look-alikes.

Is Portoro available in large formats?

Quarry output is limited; most slabs are 150-240 cm. Large-format projects require advance booking and block reservation.

Sourcing from Ligurian Black & Gold Group is handled through our desk — verified samples, confirmed availability, and one point of contact through delivery.
