What is Onyx?

Onyx is a visually striking natural stone, much, prized for its unique translucency, dramatic veining, and rich, vibrant colours. With a luxurious appearance and versatile applications, onyx has many applications in both residential and commercial design.

What is onyx?
Onyx is a form of calcite, similar in composition to marble, but with distinct characteristics. It is formed by the slow precipitation of calcium carbonate and is most often found in caves or near water springs. Over thousands of years, the minerals build up in layers, creating the stone’s signature bands of colour. These bands can vary dramatically, resulting in stunning patterns and a wide range of hues which range from warm ambers and cool greens to bold blacks and crisp whites.
One of onyx’s outstanding characteristics is its natural translucency. Thin slabs of onyx can be backlit to create a subtle glow, showcasing the stone’s depth and beauty in a way few other materials can match.

Where does onyx come from?
It’s found all around the world, including Mexico, Pakistan, Turkey, Iran, and Afghanistan. Different regions produce onyx with unique colour profiles and veining patterns. For example, Mexican onyx often features softer, pastel tones, while Iranian varieties can be vividly colourful and intricately banded.

Because onyx is relatively rare compared to other stones like granite or marble, it’s often considered a premium material. This makes it an ideal choice for architects and designers who are looking to create unusual, standout spaces.

How is onyx used in residential design?

Onyx brings a sense of drama and luxury to the home and is best used in situations where it’s natural beauty can be fully utilised and appreciated. Because onyx is softer and more porous than stones like granite, it’s best used for decorative purposes and should be sealed to help maintain its appearance.

Onyx in commercial and office spaces

In commercial environments, onyx can be used to make bold design statements. It’s particularly effective in settings where first impressions matter. However, durability can be a concern, so designers may prefer to specify onyx for vertical applications or where it will have a lighter use. Again it should be sealed to protect the surface.
