The Stone

See the natural beauty of Gris Expo up close — the surface texture, colour depth, and veining that make this quartz unique.

Style:

Plain Matte Industrial

Uniform mid-to-dark charcoal grey with fine granular texture and matte finish for solid minimal presence.

Silestone Gris Expo commits to uninterrupted mid-to-dark charcoal grey across the entire surface. There is no veining, no pattern, and no colour variation — just consistent monochromatic grey with a very subtle fine granular texture throughout. The matte or honed finish is non-reflective, giving the surface a quiet, grounded presence that absorbs light rather than bouncing it back. Gris Expo occupies the mid-dark territory between the lighter Blanco Norte14 and the near-black Night Tebas18. Its charcoal grey tone is serious without being severe, dark enough to anchor a kitchen design but light enough to avoid the practical challenges that true black surfaces present. The plain character makes it a workhorse neutral — a surface that lets every other design decision in the kitchen speak for itself. Part of Silestone's Basiq collection, manufactured in Almería, Spain with Hybriq+® technology. Minimum 20% recycled content, 100% renewable energy. Non-porous, stain-resistant despite the matte finish. Available in jumbo 327 × 159 cm slabs with a 25-year warranty. Installed by In2Stone across Hampshire.

Frequently Asked

Questions About Gris Expo

What shade of grey is Gris Expo?
Gris Expo is a mid-to-dark charcoal grey — darker than a mid-grey but lighter than the near-black of Night Tebas18 or Marengo. It reads as a solid, consistent charcoal tone with no variation, veining, or pattern. Under warm lighting it can appear slightly warmer; under cool lighting it reads as a neutral, clean charcoal.
What kitchen styles suit a plain charcoal worktop?
Gris Expo works in modern minimalist, industrial, and contemporary kitchens. White cabinets provide clean contrast; timber cabinets add warmth. It also works in all-grey tonal schemes with different shades of grey on cabinets and walls. Matte black hardware matches the surface finish, while brass adds warmth. The plain surface lets kitchen accessories and design features take centre stage.
Does the dark matte surface show marks?
The matte finish is far more practical than polished dark surfaces — fingerprints and water marks are barely visible. The mid-charcoal tone also hits a practical sweet spot: it hides both dark marks and light marks reasonably well, unlike very dark or very light surfaces which each show different types of residue.
Where is Gris Expo manufactured?
Manufactured by Cosentino in Almería, Spain using Hybriq+® technology. Minimum 20% recycled materials, 100% renewable electricity, 99% recycled water. Part of the Basiq collection with NSF food safety certification and a 25-year warranty.
What cleaning routine does Gris Expo need?
Wipe daily with a damp cloth and mild detergent. The matte finish requires no special products or buffing. For stubborn marks, use a non-abrasive cleaner. No sealing is ever needed. Gris Expo is one of the most maintenance-free surfaces in the entire range.
★★★★★
"Excellent Service and Beautiful Results - Highly Recommended! I recently had In2stone install new quartz worktops in my kitchen, and I couldn't be happier with the results. From start to finish, the experience was completely stress-free. The team was not only competitively priced but also incredibly friendly and professional throughout the entire process. They handled everything seamlessly - removing the existing sink, hob, and old laminate worktops before fitting the new quartz surfaces. The finished worktops are absolutely beautiful and have transformed my kitchen into a modern, minimalist space that I love spending time in. The quality of workmanship is outstanding, and the attention to detail really shows. I'm a very satisfied customer and would highly recommend In2stone to anyone considering new worktops. Well done to the entire team - you've exceeded my expectations!"
