Onyx Slabs


This Show Stopping Natural Stone Surface Makes The Perfect Addition to Any Remodel

Onyx slabs are a truly stunning stone that is popular for its rich colors and luminosity.  One of the features which makes onyx unique when compared to other stones is that it is a translucent stone.  Meaning, when light shines on the stone it can penetrate all the way through the stone giving the stone beauty and character that other stones can not offer!  Whether you are searching for an onyx countertop, backsplash, accent wall or table top, our team can help.  As a trusted supplier of onyx stone, we have the largest selection of slabs in Palm Beach County. Additionally, as a wholesaler and retailer you can enjoy tremendous savings on any job, large or small!  Contact us today or stop by our showroom to learn more about our natural stone slabs.

Benefits of Onyx

Translucent Stone

The translucence of onyx creates a luxurious, unique feature that you won’t get with any other stone surface.  The term translucent means that if you shine a light behind it, the beam will come through completely. Make the most of this feature by having it installed with a backlight! 



With proper maintenance, onyx is long-lasting natural stone.
