Roccia Portoghese

Product overview

Brightness, texture and Matte Silk

Lithic revisits the innate beauty of the natural stone according to Nexion designer style which opens the boundaries to new technical features with the revolutionary Matte Silk finishing.

This collection emulates the vivid and realistic shades of natural stone and harmonize the graphics of nature by representing it in sintered stone.

Lithic comes in four colours: Roccia Portoghese, inspired by the beige limestone, Vicenza Beige, the classic pale sedimentary stone, Basalto Grigio, the dark volcanic rock, and Gabbro Sfumato, gray with muted tones.
