The House of Riverstone

One material.
Mastered entirely.

While others stock every stone under the sun, we chose a different path. Since 2009 Riverstone has dedicated itself to a single material — sintered stone — and to perfecting how it is sourced, supplied and installed across the Emirates.

Compacted from pure minerals and fired above 1200°C, sintered stone outperforms marble, granite and quartz. It is immune to heat, stains, scratches and the Gulf sun.

From our Sajja facility we hold local inventory — so architects, developers and homeowners are supported from first sample to final polish, without waiting on a container.

Bookmatching

One block, mirrored.

Two consecutive slabs cut from the same block. Install the second as a mirror and the veining opens like a butterfly across the join — the difference between a wall and a centrepiece. Drag to compare.

By Colour

Start from the palette.

The Material

Stronger than stone has any right to be.

/ 01

Heatproof

Set a hot pan straight on it. Fired above 1200°C, it will not scorch, crack or discolour.

/ 02

Scratch-Immune

Harder than granite. Knives, keys and daily life leave no trace on the surface.

/ 03

Stain-Free

Near-zero porosity — coffee, wine, oil and acids simply wipe away. Food-safe.

/ 04

Sun-Defiant

UV-stable colour that never fades — engineered for Gulf summers, indoors and out.

/ 05

Food-Safe

Certified to NSF/ANSI 51 for food contact. Non-porous and inert — nothing leaches into what you prepare or serve.
