What is Onyx?

Onyx is an exquisite, translucent, semi-precious stone with luxury and sophistication.

My first encounter with Onyx was in a high-end hotel lobby, and its captivating beauty was simply unforgettable.

The dramatic, wavy patterns combined with its soft glow were so unique that I was instantly drawn to it.

Why Choose Onyx Countertops?

There are several reasons to choose Onyx for your countertops. First, its aesthetic appeal is unparalleled.

As someone who loves to entertain at home, I can’t tell you how many compliments I’ve received about my onyx countertop.

The distinctive beauty of onyx brings a touch of elegance and opulence that can transform any ordinary room into an extraordinary one.

Secondly, onyx countertops are available in various colors and patterns, allowing for unique and personalized design options.

Lastly, the natural translucency of onyx allows you to add backlighting, creating a mesmerizing glow that can form a stunning centerpiece for your room.

Popular Applications of Onyx in Interior Design

Onyx is not just for countertops. I’ve seen it used in many ways to add a touch of luxury to interior design.

Backlit onyx wall panels, for example, can make a striking statement in a living room or dining area.

Onyx fireplace surrounds can become the focal point of a room, creating a cozy yet sophisticated ambiance.

A backlit onyx sink or shower wall can feel spa-like, even in bathrooms. The creative applications are many, and the results are always stunningly beautiful.

Factors Affecting Onyx Countertop Scratching

1. Composition of Onyx

Onyx is a calcite mineral that is softer and more vulnerable to scratching than other popular stones like granite or quartz.

This inherent property means that even a seemingly harmless thing like a set of keys or an unglazed ceramic dish could leave a noticeable scratch on the surface.

When I hosted a dinner party, I learned this the hard way, and my guest placed a steel serving dish directly on my onyx countertop!

2. Polishing and Finishing Techniques

How onyx is polished and finished can also greatly influence its tendency to scratch. A high gloss finish will readily show scratches than a honed or satin finish.

Since I wanted my countertop to be the star of my kitchen, I opted for a high gloss finish. However, I quickly realized that I had to be extra careful to prevent any marks from showing up.

3. Thickness of the Countertop

The thickness of your onyx countertop can impact its resilience. Generally, thicker countertops are more resistant to scratching because they are, quite simply, more substantial.

However, even with a thick countertop, onyx is still a softer stone, so extra caution is needed. I remember when I first got my countertop installed, I was so cautious that I even used coasters for my coffee mugs!

4. Usage and Maintenance Habits

As with any material, how you use and maintain your onyx countertop can significantly affect its longevity and susceptibility to scratching.

Regular sealing, diligent cleaning, and cutting boards and trivets can help protect its surface. I now have a strict “no knives or hot pots directly on the countertop” rule in my kitchen.

And while it might seem a bit of a hassle, the beauty and elegance of the onyx make it all worth it.

Scratch Resistance of Onyx Countertops

  • The Natural Characteristics of Onyx

Onyx is undoubtedly one of the most luxurious and visually striking materials for a countertop. But, it’s essential to consider its natural characteristics.

Onyx, in its inherent beauty, is a softer and somewhat more delicate stone, which means it can be more susceptible to scratches.

As someone who loves cooking, I have found this out firsthand. Once, while whipping up a batch of cookies, my mixer hit the countertop, leaving a tiny scratch. I’ve since learned to be extra careful with my appliances!

  • Comparing Onyx to Other Countertop Materials

When it comes to scratch resistance, a comparison with other countertop materials is inevitable.

Granite and marble, for instance, are much more complex and tend to withstand daily kitchen rigors better than onyx.

I remember visiting a friend who had a granite countertop. She was nonchalantly chopping vegetables directly on the surface, something I could never do on my onyx countertop!

Pros and Cons of Onyx Regarding Scratching

Several factors come into play when weighing the pros and cons of onyx scratching.


  1. Aesthetics: Onyx is undeniably beautiful. Its unique translucence and striking patterns make it a standout material. Every time someone walks into my kitchen and gasps at the sheer beauty of my onyx countertop, I am reminded why I chose it.
  2. Uniqueness: Each onyx slab has a distinct pattern that lends your kitchen a unique and custom feel.
  3. Backlighting Possibilities: Onyx’s translucence allows for creative backlighting options, enhancing its visual appeal and adding a dramatic effect.


  1. Scratch Susceptibility: Onyx, a softer stone, is more susceptible to scratches. This means being extra cautious while using kitchen utensils or appliances on the countertop.
  2. Maintenance: Regular buffing and polishing are required to maintain the sheen and remove any surface scratches.
  3. Cost: Due to its luxurious appeal and the care required for installation and maintenance, onyx can be relatively more expensive than other countertop materials.

While there is the downside of potential scratching and the need for regular upkeep, the breathtaking aesthetics and uniqueness of onyx make it a worthy choice for those ready to commit to its care.

Preventing Scratches on Onyx Countertops

Living with onyx countertops requires a certain level of caution and care. Over the years, I’ve discovered effective ways to prevent the gorgeous surface from getting scratched.

1. Daily Maintenance Tips

My day with an onyx countertop starts with a simple cleaning ritual. I gently wipe down the surface using a soft cloth and warm water.

This helps to remove any small particles that could potentially scratch the surface. I also schedule a deeper clean with a stone-safe cleaner every couple of weeks to maintain its luster.

2. Using Cutting Boards and Trivets

I’ve learned my lesson from my friend’s granite countertop fiasco! Now, I never chop anything directly on my onyx countertop.

I always use a cutting board. It’s not just suitable for my countertop – it also keeps my knives sharper for longer.

And hot pans? They go straight onto a trivet. I keep my precious countertop safe from scratches and heat damage.

3. Sealants and Protective Coatings

Applying a sealant was something I was skeptical about initially, but it turned out to be a lifesaver. Onyx is porous, so it absorbs liquids, which can lead to staining and scratching.

I use a penetrating sealant designed for onyx that seeps into the pores and creates a protective shield. I reapply it every few months, and it’s made a difference.

4. Appropriate Cleaning Products

Last, I’ve become very particular about the products I use to clean my countertop. Acidic and abrasive cleaners are a big no-no—they can scratch the surface and damage the sealant.

I stick to pH-neutral, stone-safe cleaners. They’re gentle on the onyx but tough on grime and grease.

Repairing Scratches on Onyx Countertops

Onyx countertops are undeniably beautiful, but they can be prone to scratches. Over time, I’ve developed my routine for dealing with different types of scratches, from minor to severe, to keep my countertop looking its best.

Identifying Different Types of Scratches

We begin by identifying the type of scratch. It’s something that I’ve become quite adept at. Light scratches are usually caused by everyday wear and tear and can be shallow enough to be more annoying than damaging.

On the other hand, deeper scratches can shock you when you run your hand over them. They’re often caused by heavier impacts or dragging heavy objects across the counter.

DIY Methods for Minor Scratches

For minor scratches, I’ve discovered a simple DIY method. I put a little baking soda on a wet cloth and gently rub it over the scratch, working in a circular motion.

It’s a little bit like polishing a shoe, but you have to be careful not to apply too much pressure. After a few minutes, I rinse it off with warm water and dry it with a soft cloth.

The baking soda is a mild abrasive, buffing out the scratch without damaging the stone beneath. This technique has saved me countless times when I’ve discovered a new scratch just before having guests over!

Professional Repair Options for Severe Damage

However, it’s time to call in the professionals regarding deeper scratches or more severe damage.

I remember the horror I felt when I accidentally dropped a heavy pot onto my countertop and left a deep gouge.

Thankfully, I found a professional stone restoration service. They came, assessed the damage, and used special tools and techniques to grind down and polish the stone, effectively erasing the damage.

It wasn’t cheap, but seeing my beautiful onyx countertop restored to its former glory was worth it.


Over the years, I have keenly understood how to care for my onyx countertops. The key takeaway is that onyx, like any natural stone, is susceptible to scratches and damage.

Minor scratches can be managed at home with a simple baking soda solution that is gentle abrasive.

However, it’s best to call in professionals with the tools and techniques to restore the stone for deeper scratches and severe damage.

So, does an onyx countertop scratch easily? In short, yes. Onyx is a softer stone that is more prone to scratching than other countertop materials. But don’t let that deter you from enjoying the exotic elegance and unique charm of Onyx.

Finally, for those who have or are considering onyx countertops, remember that every scratch is not a catastrophe. Most minor ones can be managed with some DIY love.

For the more prominent scratches, professional help is available. My final advice? Don’t shy away from living and enjoying your space because of the fear of scratches.

After all, these countertops are meant to be used and loved. With proper care and maintenance, your onyx countertop can remain stunning forever.
