What Are Black Onyx Countertops?

Black onyx counters are a type of metamorphic rock that is formed from sedimentary rock, such as limestone, which has been exposed to extreme heat and pressure. This process causes the sedimentary rock to recrystallize and form a new type of material. Onyx is mined from quarries around the world and can be found in many different colours.

It has a unique appearance due to its layered structure and natural dark colour. Black onyx counters are ideal for creating an elegant, luxurious look in any kitchen or bathroom space. They look beautiful when paired with lighter or neutral-coloured cabinets and walls, and they are extremely durable, making them perfect for high-traffic areas. 

Onyx countertops also require minimal maintenance; they do not need to be sealed or waxed as regularly as other stone surfaces.

Black onyx counters come in a variety of shapes, sizes, and styles so you can create the perfect look for your home.

The Pros of Buying an Onyx Countertop 

Some of the pros of onyx counters include:

Elegant and Eye-Catching

Black onyx countertops are elegant and eye-catching, and they can really make a kitchen or bathroom stand out. Onyx is a type of stone that has a deep, rich black colour, and it has a beautiful shine that catches the light. When used for countertops, black onyx can give any room a luxurious look.

Durable and Long-Lasting

In addition to being beautiful, black onyx is also very durable and long-lasting. It is a hard stone that is resistant to scratches, stains, and heat. This makes it an ideal material for use in kitchens and bathrooms, where it will see a lot of use. Black onyx countertops can last for many years with proper care.

Easy to Maintain

Black onyx counters are also easy to maintain. They do not require any special cleaners or sealants, and they can be cleaned with warm water and soap. To keep them looking their best, it is important to wipe up spills promptly and avoid using harsh cleaners or abrasive pads.


Another advantage of black onyx countertops is that they are very affordable. They are typically less expensive than other types of stone countertops, such as granite or marble. This makes them a great option for those who want the look of stone without the high price tag.


Finally, black onyx counters are unique. Because each piece of onyx is different, no two countertops will ever look exactly alike. 

This means that your kitchen or bathroom will have a one-of-a-kind look that will be sure to impress guests.

The Cons of Buying an Onyx Countertop

Some of the cons of onyx counters include:


This means that they can absorb liquids and stains, which can be difficult to remove. If you’re not careful, your countertop can start to look dirty very quickly.


Black onyx is a very hard material (scoring a 7 on the Mohs Hardness Scale) , but it’s also quite brittle. This means that it can crack or chip easily if it’s not treated with care.


Because they’re so unique and desirable, black onyx countertops can be quite expensive. If you’re on a tight budget, you may want to consider another type of countertop material.

Not Heat Resistant

If you place hot pots or pans on a black onyx counter, it can damage the surface. You’ll need to use trivets or hot pads to protect the countertop from heat damage.

How to Care for a Black Onyx Countertop

To protect your black onyx counters from wear and tear, it is recommended that you seal them every six months using a quality sealant. This will help prevent liquid from seeping into the stone and protect it from scratches and chips. It is also important to note that black onyx counters can be quite slippery when wet so use caution when walking across them. 

Additionally, if you plan on cutting directly on the surface of your countertop you should use a cutting board to avoid damaging the stone.
