The Stone
See the natural beauty of Et Marquina up close — the surface texture, colour depth, and veining that make this quartz unique.
Deep near-black base with bold bright white diagonal veining for high-contrast dramatic marble impact.
Silestone Et Marquina strips the dark marble concept down to its purest form — deep near-solid black base, bold bright white veining, maximum contrast. The white veins course diagonally and randomly across the surface, varying significantly in thickness from delicate thread-like lines to bold broader pathways. The moderate density allows the deep black base to breathe between the vein formations, maintaining a balance between drama and sophistication. The polished or semi-polished finish is smooth, and a very fine granular texture within the black base is visible only on close inspection. Et Marquina directly references Nero Marquina — the iconic Spanish black marble quarried in the Basque Country — translating its high-contrast character into an engineered surface with consistent quality. The bold white veining against the black base creates one of the most visually impactful surfaces in the entire Silestone range. Part of Silestone's Eternal collection, manufactured in Almería, Spain with Hybriq+® technology. Minimum 20% recycled materials, 100% renewable energy. Non-porous, stain-resistant, NSF certified. Supplied 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
