Solid dark charcoal grey quartz with a warm matte finish — an uncompromising, minimalist solid surface.
Unistone Grigio strips away everything but pure, dark grey. Its uniform solid dark grey base with a subtle warm undertone approaches charcoal — entirely plain and homogenous, completely devoid of veining, movement, or pattern. The consistent matte or honed finish shows minimal reflectivity without speckling or granular texture. Grigio is the opposite of marble drama — it's dark, solid, and absolute. The warm undertone prevents it from feeling cold or clinical, and the matte finish gives it a contemporary, architectural quality. For kitchens that want the worktop to be a strong, confident anchor in a single unbroken colour, Grigio delivers without compromise. 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
