The Green Onyx is a cloudy-textured onyx with large areas of light green color with random veins of brown and rusty red color. Sometimes can show purple veins. Light green areas are generally translucent to the light. It is a fragile marble that must be reinforced with back mesh and transparent resin. The surface can show some small holes and fissures that are not imperfections or polishing defects but natural characteristics inherent to the material.
