Onyx Black Porcelain Slab

Onyx Black Porcelain reproduces the layered, almost translucent-looking banding of natural onyx — grey through brown and white, a pattern genuine onyx slabs are prized for but rarely used on benchtops given how soft and expensive the real stone is.

It’s available at 6mm for cladding, flooring, furniture, splashbacks and remodelling, or 12mm for kitchen benchtops.

Real onyx is even softer and more porous than marble, which makes it impractical for most benchtop use — porcelain reproducing the onyx look, like this one, is specifically how that pattern becomes viable for everyday kitchen and bathroom surfaces rather than display pieces alone.
