The 3D scene is generated in real time from an actual photograph of the slab and is intended as a guide. In natural stone the veining, tone and texture differ on every slab; the final choice should be made on a physical sample or slab approval.
Colour range sampled from the slab
Portoro Argento is a rare natural stone where luxury and beauty meet. White and grey veins form a magnificent contrast against an irresistible black ground, giving interiors a sophisticated touch.
The defining feature of this marble is the way the white and grey veins undulate across the black ground. The veins form animated patterns across the surface, producing a striking appearance. Each slab carries its own pattern and tonality, which is what makes it distinctive in a space.
Care note
Marble is sensitive to acids (lemon, vinegar, wine, limescale remover). Use a neutral pH cleaner, wipe up spills at once and impregnate every 1–2 years.
