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.

"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!"— Ashley ChapmanGoogle Review
