Description
Giallo Siena Classico Onyx. Rich amber and caramel-brown base with a stretched horizontal grain. Thin white and cream veins run mostly vertically and in branching lines, with a cracked brown fragment zone along the top left corner. Onyx (often called onyx marble) is a banded calcite stone; thin pieces can let light through, which is why it is often backlit. It is in stock in Sydney.

Where it works
Giallo Siena Classico Onyx suits statement pieces such as feature walls, bar fronts and backlit panels. Every slab of natural stone is different, so the pattern in the photo is the pattern you get.
Caring for onyx
Onyx is softer than marble and etches and scratches easily, so it suits low-wear areas. Seal it after installation, wipe spills promptly and clean with a pH-neutral stone cleaner.
