Onyx Slabs & Countertops

What are Onyx Slabs?

Onyx slabs are known for their incredible translucent hues. They range in a spectrum of colors, from whites and blacks to more vivid shades of green, pink, blue, and orange. In addition to their vibrant colors, onyx slabs stand out due to their bold banding. 

An onyx wall is sure to be the focal point of any room, but it’s important to consider the pros and cons of onyx installations for walls, floors, and countertops first. 

Here at Marble Systems, we only have the highest quality onyx slabs for sale. 

Onyx Slabs Usage

Onyx stone slabs are most commonly used for wall coverings in highly visible areas like hotel lobbies, public bathrooms, or home kitchens. Due to their translucency, they look incredible installed with backlighting or in a place that receives a lot of natural light. 

As we already mentioned, onyx is one of the more fragile natural stones. Although onyx slabs can be installed as kitchen countertops, bathroom vanities, or table and bar tops, we do not recommend it. As a result, we suggest that you carefully consider where you want to install your onyx slab.

Onyx countertops are beautiful, but they’re best suited for low-use kitchens. If you love to cook and are in the kitchen for hours on end, consider a more durable natural stone countertop, like granite. 

Onyx Slabs Advantages

The main advantage of onyx slabs is their incredible and eye-catching beauty. With their vivid colors, translucency, and bold bands, natural onyx walls are sure to be the focal point of any room. 

Onyx Slabs Disadvantages

Despite their beauty, there are some disadvantages to installing onyx countertops and onyx wall coverings. Onyx is a soft, brittle stone, which means it scratches more easily than a hard stone like granite.

Onyx kitchen countertops are also vulnerable to etching, which is surface damage caused by acids like coffee, lemon juice, or wine. You can safeguard your countertops by quickly cleaning spills and regularly re-sealing the surface. 

Onyx Slabs Design

This natural stone is simply stunning, with varieties of green onyx slabs, blue onyx slabs, white onyx slabs, and black onyx slabs all present in nature. Its natural vibrancy, rich bands, and translucency make it a piece of art.

As onyx slabs are translucent, they softly diffuse light, imbuing a space with a soft, colorful glow. Hence, we suggest placing your onyx wall in a space that receives a lot of natural light, so its beauty can really shine. In turn, a backlit onyx wall or a lighted onyx slab is a great way to subtly brighten a dark room and create an ambient atmosphere. 

When designing your interior, it’s important to consider the color and banding of your onyx slabs and whether it suits the space and lighting. A black onyx slab with lighting evokes a dark, moody aura and is less translucent. The warmth of honey onyx slabs pairs nicely with natural light, creating a welcoming atmosphere. 

Onyx Slabs Maintenance

Onyx countertops are high maintenance, as they’re susceptible to etching and scratching. 

Avoid bringing your countertop in contact with acidic substances. Like with any natural stone, you should clean any spills immediately to prevent staining. To clean your natural onyx stone countertop, use a neutral, non-abrasive household cleaner, preferably one for natural stones. 

To protect your natural onyx slab, we suggest regularly re-sealing. For an onyx kitchen countertop or an onyx bathroom countertop, it’s best to re-seal it once a year to protect the surface from staining. 

Onyx Slabs Applications

As onyx is a soft, brittle stone, its installation and application should be left to professionals. To give it more strength, we suggest installing an onyx slab with a fibreglass backing. 


Because onyx is a rare and luxurious stone, natural onyx slabs are more expensive than other natural stones like granite or marble.

We do not recommend onyx for countertop installations. Although they do look exquisite, onyx countertops require a lot of upkeep and maintenance due to their fragility. Moreover, they’re not heat resistant and are vulnerable to staining and scratching.

If you want the look of an onyx countertop without the high cost or maintenance, consider installing onyx porcelain slabs, which are more durable and hardwearing.

As onyx is a soft stone, it does scratch and chip more easily than a hard stone like granite. If you do choose to have a natural onyx countertop, place a pot or pans on mats or pads instead of directly on the surface.

We do not recommend natural onyx slabs for flooring applications, as onyx can scratch easily.

Onyx is a soft stone, so it can crack or chip more easily than other harder natural stones.

If you spill anything on a natural onyx slab, be sure to clean it up quickly with a non-abrasive cleaner to prevent staining. Additionally, regularly re-seal the stone's surface to protect it from staining and moisture damage.

  1. Re-seal your onyx kitchen or bathroom countertops once a year.
  2. Avoid placing metal objects, like pots or pans, or hot items directly on the surface.
  3. Clean the surface of your countertop with a non-abrasive, neutral household cleaner, ideally one meant for natural stones.

Onyx is one of the more fragile and brittle natural stones. As onyx stone countertops can chip and scratch over time, onyx slabs are most suitable for wall installations.

You should not place hot pans directly on an onyx countertop, as it is not heat resistant. Instead, place them on top of kitchen mats.

Onyx is a porous stone and therefore is not waterproof naturally. Although you can seal it to protect it from staining, onyx slabs are not suitable for wet area applications like showers.

As natural onyx is porous, it does stain easily. Regular re-sealing for onyx countertops is required.
