This week on our blog, we will continue on the different surface materials that you can use in your contracting and design projects. So far, we’ve covered Quartz, Granite, and Marble and what they are along with their advantages and qualities are; and this week, we will continue by covering Onyx.

Onyx - What Is It?

Onyx is a calcareous stone that is formed from dissolving limestone and is redeposited as a new stone. Most of us might know these as stalactites and stalagmites. Onyx is a very rare and dramatic stone with its pastel colors and its swirling patterns. It is a translucent stone which means that light transmits through it.

What Are The Qualities Of Onyx?


Onyx isn’t the most durable stone on the market. Onyx is fragile and soft which is why it requires extra care when transporting. This stone does scratch easily, but there are sealants you can use to cut back on the amount of scratches on your stone.

Cost Effectiveness

A slab of Onyx itself plus the maintenance can put a little bit of a hole in your wallet, but is a good investment if there is an area in your home that you want to stand out from the crowd.

Easy To Clean

Onyx can be easy to clean if it is properly sealed and is used with the right cleaners and if you are willing to pay the extra money to maintain these countertops, which can sometimes be quite expensive. Things like lemon juice, wine, and vinegar can stain and etch the countertops if not properly sealed.


Onyx is a beautiful stone and can come in a wide variety of colors. Since Onyx is so rare, it is great to use in an area of your home that you want to stand out from the crowd. Most of the times if Onyx is used for countertops, they are backlit, so that they stand out and makes for a dramatic backsplash.
