Cornerstone Evolution by Ergon

A range of Slate colours attuned to contemporary design trends.

Cornerstone extends its range of stones from around the world to include three new Slates in pale, luminous colours, Light Grey, Superwhite and Sand. A long-standing favourite for its authenticity, Cornerstone completes its offering of design solutions to meet modern architecture’s technical and stylistic needs.

The three new shades are available for small sizes up to large slabs and give designers complete freedom to combine shapes and colours to create interiors with a strong personality. These new shades are offered alongside the timeless Slate White, Grey and Black. The offering also includes Cornerstone 20MM, which delivers the ideal combination of exquisite appearance and outstanding technical performances in the most widely varying outdoor locations.
