Onyx is an amazing quartz stone that comes in a variety of colors that allows for beautiful interior decoration. Onyx is a great alternative to marble and has its advantages and disadvantages. More expensive than marble onyx is a soft and fragile stone that is prone to staining. It’s also rare, which makes it an entirely decorative material that we would recommend in low-traffic areas and on surfaces, and only for display purposes as stone is otherwise very easy to maintain. With the nuances out of the way, onyx is a very beautiful stone with amazing patterns and since it is much lighter than marble it lets the light through and is translucent. So the backlighting works wonders for onyx walls and countertops, giving you both a memorable sight and subdued ambient lighting.
