Pietra del Cardoso Grigio Chiaro
Pietra del Cardoso Grigio Chiaro
Pietra del Cardoso inherits the spirit of the homonymous Italian stone extracted from the mountains of Tuscany. A material appreciated for centuries due to its extraordinary longevity, resistance, style and functionality.
Nexion selected some of the most exclusive specimens conveying the essence of Cardoso into a new unique ceramic material, combining elegance with unrivalled technical qualities. Nexion has brought this stone to the next level, devising an extremely durable surface, highly resistant to chemicals, stains and abrasions which makes it particularly suitable for high traffic public spaces.
Pietra del Cardoso is a collection extremely wide and versatile, divided into six colors, one size, and two surfaces. surfaces.
