Riverstone reinterprets river stone in a contemporary style, preserving its material authenticity while transforming it into a modern architectural language. The collection is available in six colours and three coordinated textures. The range of formats includes the large 120×280 cm slab, the practical 60×120 cm size and the square format, which is also available in the outdoor R11 version. It is a complete and coherent structure, designed to meet both technical and aesthetic requirements in any design context. The three graphic variations — Sand, Rock and Full Rock — offer different levels of aesthetic intensity, ranging from the understated minimalism of Sand, to the opulence of Full Rock, with the dynamic balance of Rock in between. The result is a refined and versatile style that fits naturally into classical interiors, modern spaces, and contemporary outdoor designs.
