LUMEN takes Onyx as its inspiration, translating the luminous depth of natural stone into visual and tactile expression on porcelain surfaces. 16 coordinated faces ensure seamless, natural-looking continuity across installations, as if cut from a single vein. The soft matte antique finish imparts a time-worn gentleness—subtle in sheen, refined in touch. Near-zero water absorption delivers outstanding stain resistance and durability, suitable for residential, hospitality, and commercial applications. LUMEN brings together the visual richness of natural stone and the quiet tactility of an aged surface. A softer, quieter way to express luxury. Suitable for walls and floors.
