The Stone
See the natural beauty of Valiente Black up close — the surface texture, colour depth, and veining that make this quartz unique.
Deep charcoal-black quartz laced with fine white-grey veining — a bold, dramatic surface that commands attention.
Coante Valiente Black is unapologetically dark and dramatic. Its deep charcoal-black base provides a powerful backdrop for web-like clusters of fine, thread-like veining in cool grey and near-white tones. The veins traverse the slab diagonally and horizontally in intricate, interconnected formations, their light tones creating a stark contrast against the dark surface that draws the eye across the worktop. The polished finish adds a subtle sheen that heightens the drama, picking up light and giving the surface depth that shifts depending on the angle. Built from 93% natural stone with the same dependable non-porous, stain-resistant construction as the rest of the Coante range, Valiente Black delivers statement looks without compromising on durability. Available in 3200 × 1600mm jumbo slabs with 20mm or 30mm thicknesses, and backed by a 25-year warranty. Supplied and installed by In2Stone throughout 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
