The Stone
See the natural beauty of Diamant up close — the surface texture, colour depth, and veining that make this quartz unique.
Light warm grey quartz with bold dark charcoal veining and intricate grey undercurrents — a dramatic marble surface.
Unistone Diamant commands attention with bold, sweeping veining on a warm grey canvas. Its light warm grey base provides a soft yet distinct backdrop for prominent medium to broad veins in deep dark brown-grey or charcoal that dramatically traverse the surface in largely diagonal, sweeping movements. Beneath these bold lines, a dense intricate network of finer lighter grey veining subtly swirls and feathers across the background, adding depth and natural complexity. The polished finish reflects light gently, bringing the high-contrast interplay between the bold charcoal veining and the intricate lighter undercurrents into focus. Diamant has a genuinely geological quality — the layered veining suggests stone that was formed under immense pressure. Manufactured by Brachot with Through Tone Technology. Over 90% natural quartz, NSF certified. 15-year warranty. Available in standard and jumbo slab formats. Supplied and 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
