Drag the slab to turn it, or use the arrow keys. Switching finish re-renders the surface — polished throws a hard specular, the abraded finishes open the surface up and knock the colour back.
Brown semi-precious
Brown Onyx
Dark chocolate banding with amber transmission.
Unlit it is nearly opaque chocolate; lit from behind the bands turn amber and the whole panel opens up. The biggest difference between lit and unlit of any onyx we handle.

Photographs
Brown Onyx in the yard
We are photographing this material now. Until the shoot is done, the turning slab and the close-up below are renderings, and the honest answer to “what does it actually look like” is a sample in your hand.
No photographs yet. Ask us for the current slab and block photographs of Brown Onyx — we shoot them on request, in the yard, with a scale in frame. A cut sample goes out by courier the same week.
Laid out
Brown Onyx across a floor
A photograph shows one slab on a stand. This shows the stone tile after tile — where the pattern repeats, how far the tone drifts across a batch, and what the joint does to it. Every tile here is cut from a different part of the surface, the way material comes out of a real crate.
Indicative layout. Tone drift is deliberate — no two tiles from one batch match exactly, and a laid floor should never look like one photograph repeated.
Surface
Brown Onyx, close up
The slab above turns; this is the same stone at the size it sits in your hand. Change the finish and it re-cuts.
Roughly a 130 mm span of Brown Onyx, polished. A rendered preview, not a photograph of stock — ask for a physical sample before you specify.
