It takes thousands of years for Onyx to form. Onyx is a sedimentary rock, formed as stalactites and stalagmites in cave interiors. These characteristics give this stone a translucent crystalline structure that can be backlit for a dramatic focal point. Onyx is often confused with marble, but is a distinct rock type and actually transparent!
Onyx Practicality and Functionality
Onyx is extremely rare and with that, comes a price. It is a high maintenance stone, but more importantly, it lasts when cared for properly. Like marble, it is porous and is susceptible to etching and scratching, so it is recommended for lower traffic areas and not for applications such as kitchen or bathroom countertops. Onyx is a fragile stone material that often comes in smaller slabs, but making it easier to handle when compared to other stone types. Being that it is more lightweight, it’s a great option to consider for inlays or vertical applications.
