Natural Textured Industrial Stone Effect

Deep charcoal-black base with dense grey and brown mottling in stratified bands creating raw slate-like texture.

Silestone Raw D plunges into the dark end of the spectrum with a very deep charcoal grey base that sits close to black. Across this dark ground, a dense pattern of lighter grey and subtle warm brown-grey mottling emerges — a combination of fine web-like veining and irregular broader patches that layer together in roughly horizontal bands. The stratified movement suggests natural geological formation, and the finish is granular and somewhat pitted rather than polished, reinforcing the raw, unprocessed character. This is not a marble effect. Raw D channels the aesthetic of natural slate or dark metamorphic stone, where the interest comes from texture and tonal variation rather than bold veining. The dense patterning means the surface is never flat or monotonous despite its dark colour — lighter grey details and warm brown-grey accents emerge at different angles and in different lighting conditions. Part of Silestone's Raw collection, manufactured in Almería, Spain with Hybriq+® technology. Minimum 20% recycled content, 100% renewable energy, 99% recycled water. Non-porous, stain-resistant despite the textured finish. Supplied in jumbo 327 × 159 cm slabs with a 25-year warranty. Installed by In2Stone across Hampshire.

Frequently Asked

Questions About Raw D

What does Silestone Raw D actually look like?
Raw D is a very dark charcoal grey — almost black — with dense lighter grey and warm brown-grey mottling visible across the surface. The patterning runs in roughly horizontal stratified bands, and the finish is granular and textured rather than polished. The overall effect is of natural slate or dark metamorphic stone. It is one of the most textural surfaces in the Silestone range.
What kitchen style suits Raw D?
Raw D works in industrial-leaning and contemporary kitchens where raw materiality is valued. It pairs well with exposed brick, concrete walls, timber shelving, and matte black hardware. Light oak or white cabinetry creates effective contrast against the dark surface. It is less suited to traditional or ornate kitchen styles where a more refined finish is expected.
Is Raw D as durable as polished Silestone surfaces?
Yes. The textured finish does not affect the material's performance — Raw D has the same stain resistance, scratch resistance, and non-porous properties as any polished Silestone surface. The Hybriq+® composition is consistent regardless of surface finish. The textured finish actually has a practical advantage: it hides fingerprints and water marks far better than a glossy polish.
Where is Raw D manufactured?
Raw D is produced at Cosentino's facility in Almería, Spain using Hybriq+® technology. The composition includes minimum 20% recycled materials, and production runs on 100% renewable electricity with 99% recycled water. It carries NSF and Greenguard certifications for food safety and low emissions.
How do I clean a textured finish like Raw D?
Clean daily with a damp microfibre cloth and mild detergent. The textured finish may hold onto food particles slightly more than a polished surface, so a gentle scrub with a soft brush can help in kitchen areas. Despite the granular texture, the surface is still completely non-porous — nothing can penetrate. Avoid abrasive scourers that might smooth out the intentional texture over time.
★★★★★
"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!"
