Natural onyx from Tanzania with an intense Bordeaux color enhanced by shades ranging in color from orange to brick. The purple onyx, depending on the direction of the cut, has either a cloudy or a linear structure: our slabs feature a cloudy structure with a wealth of color shades ranging to the hot tones of pink. Intense colors make Onice Viola a truly perfect material for ambitious design projects: the transparency of this material makes it suitable for backlit interior elements that give each room a touch of exclusivity.
