Onyx’s fascinating patterns and unique translucent qualities are one of the reasons people choose it. But these same qualities suggest that careful thought must be given to the location of onyx countertops and what their purpose is going to be. Typically, onyx stone is well-suited for furniture pieces, bathrooms and fireplace surrounds. Because onyx is translucent, backlighting can be used to draw more attention to the overall stone as well as its little intricacies. This is one stone that you’ll find more often used in vertical applications (like the front of a fireplace) than that of marble or granite.
