Portland Stone takes a fresh look at a very ancient limestone and offers the contemporary design world the ancestral strength of a material that has survived geological eras with its charisma intact. The five shades – Sand, Talc, Ash, Lead, Anthracite – offer different readings of the natural material with a highly versatile aesthetic. Tiles are available in two main versions, inspired by two stone cutting methods: Cross-Cut, for a mottled look with main shade variations and distinctive details; and Vein-Cut, for an elegant, immaculate striped effect.
