THE-CRYSTALS-ALBA SLAB
White onyx-effect slab, warm light and subtle depth
Alba is Optimum Surfaces’ porcelain stoneware slab that interprets crystal onyx in its most immersive form, enriching The Crystals collection with a bright layered surface.
Warm ivory tones and subtle variations, combined with refined patterns, create an elegant sense of depth, making it suitable even for the most contemporary projects.
Delicate veining emerges from the material, reminiscent of the first rays of light passing through stone, guiding the eye through subtle transparencies and layered depth.
