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.
Grey marble
Imperial Grey Dark
Also sold as Imperial Grey Extra
The deep-toned selection of Imperial Grey, veins on charcoal.
Same bed, darker selection. Blocks running to charcoal rather than silver are cut separately and sold as Imperial Grey Dark, where the pale veining reads as a bright line rather than a soft drift. It is a dramatic stone in small quantities — bathroom walls, bar fronts, lift lobbies — and it pairs naturally with its lighter grade on the same project.

Photographs
Imperial Grey Dark in the yard
Photographs of our own blocks, slabs and finished work. Slab photography shows one slab — the block it came from is what you are quoted against.
Laid out
Imperial Grey Dark 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.
In the room
Imperial Grey Dark against your wall colour
Nobody buys stone on a white background. Put Imperial Grey Dark on the floor, up the wall or across a worktop, set the colour it will actually sit against, and change the light — the same three questions every client asks on a site visit, answered before the sample ships.
A scene, not a render of your project: proportions are indicative and colour on a screen is never the colour in a room. Send us the drawings and we will lay the real slab sizes out against your setting-out.
Surface
Imperial Grey Dark, 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 Imperial Grey Dark, polished. A rendered preview, not a photograph of stock — ask for a physical sample before you specify.
