Onyx slabs
Onyx is a banded chalcedony, typically translucent with dramatic parallel stripes in colours ranging from warm orange and honey through green and even pink. It is the most visually dramatic stone we work with — and also the most fragile and expensive.
How onyx is used
Because it is translucent, onyx is almost always used with backlighting. Placed behind a bar, reception desk or feature wall with LED lighting behind it, the stone glows and the banding comes alive. It is rarely used for benchtops because it is soft, porous and prone to cracking under impact.
Common applications
- Backlit feature walls in commercial lobbies and high-end homes
- Bar fronts and reception desk cladding
- Decorative wall panels
- Custom furniture tops and display plinths
What to know
Onyx slabs are thin (typically 10–12mm) and need to be laminated to glass or a backing panel for structural support. Cuts must be done with waterjet to avoid cracking. Because of the material cost and fabrication complexity, onyx projects are quoted individually. Bring us your design ideas and we will work through the technical requirements with you.
