The House of Riverstone

One material, mastered entirely — the story of how we became the UAE's sintered stone specialists.

Since 2009

One material.
Mastered entirely.

While others sell 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 everything about how it is selected, supplied and installed in the Emirates.

Compacted from pure minerals and fired at over 1200°C, sintered stone outperforms marble, granite and quartz — immune to heat, stains, scratches and the Gulf sun. It is the surface nature would have made, given another thousand years.

From our Sharjah facility, we hold local inventory and support architects, developers and homeowners from first sample to final polish.

The Material

Stronger than stone
has any right to be.

/01

Heatproof

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

/02

Scratch-Immune

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

/03

Stain-Free

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

/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.

The performance of porcelain, the soul of natural marble — in slabs up to 20mm thick.
