Onyx Stone Slabs

Every slab of onyx is rich with a stunning appearance and a storied history. At Stone Boutique, we offer an exclusive collection of onyx stone slabs curated for those searching for inspired designs and an innovative buying experience.

Why Onyx Is One of a Kind

This microcrystalline form of quartz is formed in the heat of volcanic rocks and lava. While usually featuring black and white bands, onyx can also contain red, brown, green, gold and other colors. The layers of color can be dramatic or subtle, allowing you to choose the perfect look for each project.

Known for its dramatic veining and translucent quality, onyx glows when backlit, bringing an almost ethereal beauty to interiors. No two onyx stone slabs are alike. Every cut reflects the mineral artistry beneath the Earth’s surface.

Onyx is considered rarer than many natural materials used in design. Many designers also love it for its rich history. Onyx has been used for design since ancient times, so using it brings the romance of the past into your space.

Proper care and maintenance are simple. Onyx is best used in low-traffic areas where its beauty can be appreciated without heavy wear. With a little care, it can last a lifetime. A gentle cleaner and regular sealing will preserve its appearance for years.

Where Onyx Belongs in Your Space

Traditionally, onyx was used for jewelry and small pieces because of its rarity. However, innovations in mining have allowed it to be used for designs in residential and commercial spaces.

Onyx is most often used in statement areas where its natural luminosity can shine. Bar fronts, wall panels, bathroom vanities and dramatic fireplace features are ideal places for onyx. Onyx countertops also create visual depth and sophistication, perfect for powder rooms, reception desks and show kitchens.

While onyx is often used indoors, it is also used for outdoor kitchens or water features in some milder climates. If you are interested in using onyx outdoors, consult with the expert team at Stone Boutique to ensure it will work in your space.
