Onyx is a type of marble that has a lot of the same properties as marble. The distinctive elements of each slab are the amazing patterns and veining. Onyx is available in a wide range of colours and patterns, with varying degrees of patterning. The absence of opacity in Onyx is a fascinating trait. Because onyx is more translucent than marble, it's a great choice for lighting or creative applications like a backlit wall or surface that showcases the patterns.
