The Stone
See the natural beauty of Calacatta River up close — the surface texture, colour depth, and veining that make this quartz unique.
A confident Calacatta-style quartz with cool grey veining in clear directional bands connected by fine crackle lines.
Calacatta River channels the flowing energy of natural marble with its medium grey veining sweeping horizontally across a clean white base, connected by fine hairline crackle lines. The cool-toned grey veins carry a slight blue undertone, creating a confident directional pattern with clear movement and purpose. Composed of 93% natural stone with a polished finish, Calacatta River is available in Jumbo 3200 x 1600 mm slabs at 20mm or 30mm thickness. This non-porous, stain-resistant quartz is protected by a 10-year warranty.

"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
