The Look of Natural Onyx, Engineered for Modern Living
Caesarstone 509 Onyxa captures the elegant, flowing beauty of natural onyx in a high-performance porcelain surface. Wavy layers of warm white and translucent beige are beautifully accented by bright white highlights and subtle golden rust deposits, creating a sophisticated surface with organic veins that evoke a genuine sense of natural movement.
Part of Caesarstone’s exclusive Supernatural Ultra Collection, 509 Onyxa delivers the drama and depth of natural stone with the practical advantages of advanced porcelain — larger slabs, thinner profiles, superior durability, and true indoor/outdoor versatility.
