Belgian Pierre Bleue stone, created more than 300 million years ago when the country was covered by a tropical sea, inspires Unique Bleu, a new ceramic collection from Stone Source. The range features two-color shades: Gris and Anthracite, reproducing all the beauty of a limestone popular for architecture down the ages thanks to its distinctive color naturally varying from grey to blue and black, and its extremely compact, uniform consistency. The range comprises a large number of sizes and thicknesses, to express the striking beauty of Pierre Bleue in the most widely varying architectural contexts, always meeting technical demands with exquisite looks.
