Elegant aesthetic
The strength and charisma of Alpine stone.
Cornerstone Alpen brings Ergon's gaze to two of the oldest and most iconic alpine stones, Valser and Bavaria Stone, enhancing their chromatic and geological specificities through a design faithful to the cleanliness of the slits in the quarry, from which spontaneously emerge veins and details capable of surprising.
