The Stone
See the natural beauty of Calacatta Alya up close — the surface texture, colour depth, and veining that make this quartz unique.
Bold grey veining on a luminous white base — the drama of calacatta marble with the durability of quartz.
Calacatta Alya captures the essence of premium Italian calacatta marble with a striking diagonal vein structure that sweeps across a luminous white base. The central vein carries a blend of grey and warm gold-brown tones, with fine crackling detail along its edges that gives it a convincingly natural character. Lighter grey veins radiate outward in supporting patterns, while the white background shows subtle tonal variation with faint grey clouding beneath the surface — avoiding the flat, lifeless look that plagues lesser marble imitations. Part of Radianz's Cirrus Prestige collection and manufactured using advanced Nano Ink Technology, this surface is available in jumbo XL slab sizes (330 × 165cm) — perfect for spanning large kitchen islands with minimal joins. The 93% quartz composition delivers Mohs 7 hardness, zero water absorption, and complete stain resistance. LOTTE Chemical backs this surface with a 15-year residential warranty, giving homeowners the luxury aesthetic of calacatta marble without a gram of the anxiety.

"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
