Deep off-black sintered stone with very fine granular texture and matte finish — a dark, quietly solid surface.
Dekton Sirius — named after the brightest star — delivers darkness with material depth. Its very deep charcoal grey base with subtle warm brown undertone presents as off-black. No veining or bold pattern is visible — the surface appears largely uniform with only very fine consistent granular texture creating extremely subtle random mottling. The matte or honed finish has no reflective sheen. Sirius is the darkest solid design in the Dekton range. The warm brown undertone prevents it from being pure cold black — there's a quiet warmth within the darkness. The fine granular matte texture adds material honesty, distinguishing it from lacquered or painted surfaces. Engineered by Cosentino using TSP technology. Null porosity, UV resistant, A1 fire certified. 25-year warranty. Carbon neutral. 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
