The Stone
See the natural beauty of Calacatta Supreme up close — the surface texture, colour depth, and veining that make this porcelain unique.
Off-white porcelain with flowing cool grey calacatta veining — a classic, composed marble-effect surface.
Optimum Calacatta Supreme presents the most classic calacatta interpretation in the Optimum marble collection. Its off-white to very light cream base is crossed by extensive diagonal veining flowing from upper left to lower right in shades of soft cool grey to light charcoal. The veins range from fine, delicate lines to wider, more diffused bands, with lighter translucent smoky grey clouds that blend softly into the background, creating moderate to dense coverage across the surface. The polished finish is smooth and refined, emphasising the flowing, composed quality of the veining. Where Matarazzo is fractured and busy, Supreme is structured and flowing — a more traditional calacatta interpretation that suits kitchens where classic marble beauty is the goal. As porcelain stoneware, it brings complete heat resistance, acid immunity, and maintenance-free performance. Manufactured in extra-large 1840 × 3300mm slabs from 100% natural raw materials. 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
