Is Onyx Good for Kitchen Countertops?

Onyx, a naturally translucent semiprecious stone, has long captivated homeowners with its opulence and unique light-play. Often used in jewelry and decorative items, onyx is now seen as a potential countertop material for luxury kitchens.

Choosing the right countertop material is critical in kitchen design; it significantly contributes to its functionality, durability, and aesthetic appeal.

This blog post aims to delve into the world of onyx countertops, discussing their pros and cons and helping you to consider whether this stone could be the perfect choice for your kitchen.

What is Onyx?

Characteristics of Onyx

Did you know that Onyx isn’t just a beautiful stone but has a rich history, too? Onyx is a form of chalcedony, which is itself a type of quartz.

This stunning stone has alternating layers of color, and this unique banding distinguishes it from other types of chalcedony.

The bands are parallel and consistent, giving the stone a unique aesthetic appeal. When I first laid my eyes on an onyx stone, I was mesmerized by how the bands followed a rhythmic pattern, almost like nature dancing to its music.

Natural Variations and Colors

What will truly surprise you, as it did me, is the natural color variations of onyx. Onyx is usually black, but it can also come in various beautiful shades, including white, green, brown and pink.

The banding pattern usually contrasts with the primary color, creating a dramatic effect. So if you love a sense of drama and uniqueness in your kitchen, onyx might be the perfect choice.

How Onyx is Formed

Have you ever wondered where this beautiful stone comes from? Onyx is formed in the gas cavities of lava.

Yes, you read that right. It’s as if Mother Nature decided to create something extraordinarily beautiful from something as destructive as lava.

The bands form as different minerals seep into the stone over time. The first time I found out about this, I was awestruck.

The idea that something so beautiful and unique is formed under such intense conditions is a testament to the surprises that nature has in store for us.

Pros of Using Onyx for Kitchen Countertops

1. Aesthetic Appeal

  • Unique veining and patterns

The first time I saw an Onyx countertop, I was struck by its intricate veining and patterns. Each slab of Onyx is unique – its beauty comes from the distinctive bands formed naturally over time.

No two Onyx countertops will ever be the same, ensuring your kitchen is one-of-a-kind.

  • Translucent properties

One of Onyx’s most extraordinary features is its translucency. It can light up when exposed to backlighting, giving it a warm, radiant glow.

The first kitchen I saw with backlit Onyx countertops was breathtaking. It was as if the countertop was a source of light, creating an inviting and warm ambiance that made the kitchen the heart of the home.

2. Luxurious Appearance

  • Unrivalled Elegance

Onyx is the epitome of luxury. It’s not your run-of-the-mill stone; rather, it’s an exceptional choice that instantly imbues your kitchen with an aura of elegance and sophistication.

Its unique veining, combined with its unrivalled translucency, gives Onyx an opulent charm that’s hard to match. When I decided to remodel my kitchen with Onyx countertops, my aim was to create a space that was functional, yet exuded a luxurious feel.

  • Unprecedented Admiration

The result was nothing short of extraordinary. From the moment my friends and family stepped into my newly remodelled kitchen, they were awe-struck.

Their eyes were drawn to the radiant glow of the backlit Onyx, and they were captivated by the distinct veining that adorned each slab.

The elegant aesthetic was compelling, but more than that, it was the sense of luxury that the Onyx countertops brought to my kitchen which truly set it apart. This stone’s natural beauty and the luxurious ambiance it creates are truly unparalleled.

4. Potential for Increasing Property Value

The adage “Kitchens sell houses” rings particularly true in the real estate market. A well-designed kitchen can often sway the decision of prospective buyers, primarily if it includes high-end features, like Onyx countertops.

These countertops not only enhance the aesthetic appeal of your kitchen but also potentially add significant value to your property.

The distinctiveness and luxe of Onyx make it highly desirable. When I decided to sell my previous house, it was the Onyx countertop that became the highlight during house showings.

Prospective buyers were utterly enchanted by the unique aesthetic and the luxurious vibe that the Onyx countertop provided.

It wasn’t just the strikingly radiant glow of the backlit Onyx or the captivatingly distinct veining that drew their attention; it was the overall ambiance of opulence that the Onyx provided.

Moreover, the rarity of Onyx elevates it beyond an ordinary countertop material, making it a feature of value and exclusivity.

It’s an upgrade that doesn’t just enhance your kitchen’s appeal visually but also monetarily. The Onyx countertop was not just another feature of the house; it was a major selling point, a deal clincher that significantly boosted the property’s market value.

Therefore, investing in an Onyx countertop can yield potential returns, making it a worthwhile consideration for homeowners planning a kitchen remodel.

5. Range of Color Options

One of the most compelling attributes of Onyx countertops is the broad spectrum of color options they offer. Ranging from the purest white to the deepest black, Onyx encompasses a palette that includes shades of browns, reds, and greens.

Whether you’re seeking a countertop that creates a dramatic contrast or harmoniously blends with your kitchen’s color scheme, Onyx’s color versatility can cater to your aesthetic preferences.

I recall visiting a house where the kitchen featured a light green Onyx countertop. It perfectly complemented the overall earthy tone of the kitchen, adding a touch of elegance while maintaining a natural vibe.

The homeowner’s choice of this particular Onyx hue was a testament to the material’s versatility in design and its ability to adapt to various kitchen styles.

6. Smooth and Polished Surface

Last but certainly not least, the surface of Onyx is incredibly smooth and polished. Its texture is a tactile delight, inviting one to run their hands over its seamlessly polished surface.

A personal memory that underscores this attribute is baking cookies with my children on our Onyx countertop.

The cool, smooth stone served as an ideal baking surface, and the children reveled in the sensation it lent to their small, dough-covered hands.

It was not just a countertop, but an instrument that facilitated the creation of cherished family memories.

Cons of Using Onyx for Kitchen Countertops

While the aesthetic appeal of Onyx countertops is undeniable, there are a few drawbacks to this material that are worth pondering before making an investment.

1. Scratches

Onyx is a softer stone compared to granite or quartz. Every now and then, when I’m preparing food on my Onyx countertop, I have to be extra mindful not to use a sharp knife directly on the stone.

A few times, I’ve accidentally left small scratches. These imperfections are subtle but, over time, they can become more noticeable.

2. Stains

Another aspect of Onyx’s delicacy is its proneness to staining. I vividly remember a dinner party when a guest accidentally spilled red wine on the countertop.

Despite my frenzied efforts to clean it immediately, a faint stain remained, requiring professional treatment.

3. Chipping and Cracking

Onyx can also chip or crack if subjected to heavy impact. A dropped pot or an accidental knock with a heavy object can damage the countertop. In my experience, a broken glass jar was all it took to leave a small chip on the edge of the countertop.

4. High Maintenance Requirements

As an owner of an Onyx countertop, I can attest to the significant upkeep it requires. Regular sealing is necessary to prevent stains and scratches.

Additionally, cleaning must be done with non-acidic products, which can sometimes be a hindrance when you’re dealing with stubborn stains.

5. Limited Durability Compared to Other Materials

While Onyx is undoubtedly beautiful, it lacks the durability of materials like granite or quartz. This was a point of contention when my wife and I were deciding on our kitchen remodel.

We knew that with our three kids and our love for cooking, our kitchen would see heavy use. While we loved the look of Onyx, we had to seriously consider whether it would withstand our busy lifestyle.

6. Cost Considerations

Lastly, it’s important to consider that Onyx is a premium countertop material. Its unique beauty comes with a price tag to match.

I remember feeling a pinch in my wallet when I received the quote for our Onyx countertop. It was definitely a substantial investment, one that may not suit every homeowner’s budget.

Installation and Maintenance Tips

Professional Installation

It’s essential to seek professional help when installing an Onyx countertop. While I am pretty handy, I quickly realized that this was not a job I could tackle on my own.

The material is incredibly delicate, and one wrong move can lead to expensive damage. The professionals have the right tools and experience to ensure a smooth and successful installation.

Sealing Requirements

Sealing is fundamental to prolonging the lifespan of your Onyx countertop. During our kitchen remodel, I learned that Onyx countertops should be sealed at least once every two years, but more often if you use your kitchen heavily. The sealant acts as a protective layer, helping to prevent stains and damage from daily wear and tear.

Cleaning and Maintenance Recommendations

Cleaning an Onyx countertop requires a gentle touch. I’ve found that using a soft cloth soaked in warm, soapy water works best for daily cleaning.

Avoid acidic or abrasive cleaners – they can etch the surface and cause irreversible damage. Remember, the rule of thumb with Onyx is: the gentler, the better.

Protecting Against Damage

While damage can’t always be avoided, taking certain precautionary measures can help. I always use cutting boards when preparing food to avoid scratching the surface.

Using coasters under glasses is also a good idea to prevent rings and water stains. Furthermore, reposition heavy appliances occasionally to prevent indentation marks. With these simple steps, you can keep your Onyx countertop looking its best for years to come.

Comparing Onyx to Other Countertop Materials

The world of countertops is vast, and Onyx is just one of many options. I’ve had the opportunity to interact with a variety of materials and here’s how Onyx stands up against them:


Granite is by far one of the most durable countertop materials. It’s scratch-resistant and heat-resistant, which is a huge plus for an avid cook like myself.

But Onyx has an undeniable allure. Its translucency and ability to be backlit just can’t be matched by granite. If you’re after a showstopping centerpiece for your kitchen, Onyx might be the choice for you.


Marble, with its timeless elegance, was a serious contender when I was deciding on my kitchen’s countertop.

However, Onyx won me over with its unique, striking patterns. I found that while marble can sometimes show stains quite easily (especially if you enjoy red wine as much as I do), sealing my Onyx countertop more frequently helped mitigate this issue.


Quartz countertops are tough and non-porous, making them great for resisting stains. They also come in a wide range of colors. However, the appeal of Onyx lies in its natural beauty, with each piece being unique, something that engineered quartz simply cannot replicate.

Solid Surface

Solid Surface countertops are a budget-friendly option and they offer a huge variety of color options. But they lack the depth and three-dimensional quality of Onyx. When you look into an Onyx countertop, you can see layers upon layers of mineral deposits, creating a sense of depth that’s absolutely mesmerizing.


Laminate was the material of choice in my first apartment. It was cost-effective and surprisingly resilient.

However, compared to Onyx, laminate just doesn’t have the same high-end look and feel. There’s something about the cool touch of Onyx under your hands that laminate just fails to deliver.

Choosing a countertop material is a big decision. It has to balance aesthetics, functionality, and budget.

While Onyx may require a bit more love and care than other materials, its beauty makes it worth every extra minute spent on maintenance.

Is Onyx Suitable for Your Kitchen?

Making the decision to use Onyx in your kitchen can seem daunting. After all, it’s a significant investment. However, considering a few key factors might help you make an informed decision.

Factors to Consider Before Choosing Onyx

1. Usage Patterns

One of the first things I considered was my kitchen usage patterns. Onyx, while beautiful, might not be the best choice if your kitchen sees heavy-duty use on a daily basis due to its delicate nature.

However, if your kitchen is primarily used for light meal prep and occasional entertaining, Onyx could be a perfect fit.

As someone who loves to experiment with different cuisines and hosts dinner parties often, I had to weigh the practicality of Onyx against its enchanting beauty.

2. Budget

The financial aspect is indeed a critical point to ponder upon when considering Onyx as your countertop material. Since it’s a high-end material, it’s going to carry a price tag to match that status.

However, when the cost aspect is viewed through long-term lenses, the perspective changes. It is no longer just a kitchen countertop, but an investment into your home.

An Onyx countertop is not just a workspace, it is a conversation starter, a piece of art, a centerpiece that adds a touch of elegance and luxury to your kitchen.

Its unique beauty and high-class feel are sure to enhance the overall value of your home, making its higher cost worth contemplating.

Furthermore, by maintaining it well, the life of the Onyx countertop can be extended, further justifying the investment.

It’s crucial to ponder whether your budget can accommodate this investment, keeping in mind the long-term benefits it can bestow on your home.

3. Maintenance Commitment

In considering onyx, it is vital to be cognizant of the maintenance commitment required to preserve its natural elegance. Onyx, being a porous stone, could be susceptible to staining.

Therefore, regular sealing is crucial to keep it stain-free and to maintain its resplendent shine. This might sound like extra work, but remember, no great thing comes without effort.

Additionally, being mindful of spills, especially acidic substances like lemon juice or vinegar, is crucial as they may etch the surface.

Swift clean-up of any spills can prevent potential damage. While this might demand a higher degree of vigilance than other countertop options, the resulting grandeur is unparalleled.

I have found that this maintenance commitment, though substantial, is truly worth it given the extraordinary beauty and uniqueness that Onyx brings to my kitchen.

The effort invested in taking care of it pays off when it serves not just as a functional countertop, but as a conversation piece that exudes luxury and sophistication.

Alternatives to Onyx if it Doesn’t Fit Your Needs

If, after contemplating all these factors, you find that Onyx doesn’t align with your needs, fret not. A myriad of other countertop materials are available, each bearing its own unique benefits.

Quartz Countertops

Quartz is one such alternative, renowned for its durability. This man-made stone is non-porous, minimizing the risk of staining and eliminating the need for sealing.

It is available in a wide array of colors, imitating the look of natural stones like granite and marble, and offers a more uniform pattern.

Laminate Countertops

On the other end of the spectrum, if budget is a concern, laminate countertops make for a cost-effective choice. They come in various colors and patterns, capturing the essence of more expensive materials.

Though laminate may not have the same longevity or resistance to heat as stone countertops, its affordability and versatility make it a worthy consideration.

Granite Countertops

Granite could be another viable option, combining durability with natural beauty. Each slab of granite is unique, adding an element of exclusivity to your kitchen. Granite is heat-resistant, scratch-resistant, and, when sealed properly, resistant to stains.

Marble Countertops

For those seeking a touch of luxury without opting for Onyx, marble could be the answer. Its timeless elegance and heat resistance make it a favorite among many homeowners. However, being porous, it requires regular sealing to prevent staining.

In the end, it boils down to finding the material that perfectly aligns with your needs, aesthetics, and budget.

The key is to balance practicality with style – ensuring your countertop not only looks good but also performs well under your specific usage conditions.

If, after considering all these factors, you find that Onyx is not the best fit for your needs, don’t worry. There are plenty of other countertop materials that offer their own unique benefits.

I’ve been through this process before, from considering quartz for its toughness to laminate for its cost-effectiveness. Ultimately, it’s about finding the material that best aligns with your needs, aesthetics, and budget.


In my personal journey of home renovation, I’ve weighed the advantages and disadvantages of various countertop materials, including onyx.

Onyx, with its stunning natural patterns and luminous finish, can undoubtedly transform your kitchen into a work of art. It’s a conversation starter, a centerpiece, and a statement of luxury.

However, it does require a bit more care than some other options. It’s softer, and thus more susceptible to scratches and chips. Additionally, it can be porous if not properly sealed, making it prone to staining.

While I’ve gleaned a lot from my experiences, I can’t stress enough the importance of professional guidance when making such a substantial decision.

A countertop is a significant investment and an integral part of your kitchen – it needs to be practical, durable, and aesthetically pleasing.

A professional can help you navigate these considerations, unearthing pros and cons that may not be immediately apparent.

When I was considering marble, for example, a professional pointed out its need for regular sealing – something I hadn’t thought about before.

Remember, at the end of the day, this choice is about your needs, your preferences, and your lifestyle. Don’t rush into a decision based on fleeting trends or the urge to keep up with the Joneses.

Carefully weigh the pros and cons of each option and think about how they align with your personal requirements. I remember when I was drawn to the affordable appeal of laminate, only to realize that I preferred the durability and heat resistance of granite.

Your countertop should be a balance of functionality, durability, and beauty, so take your time, seek professional advice, and make an informed decision that you’ll be happy with for years to come.
