The Stone
See the natural beauty of Onice Bianco Extra up close — the surface texture, colour depth, and veining that make this porcelain unique.
Colour:
White A luminous, dreamy white onyx-effect porcelain with ethereal grey cloud-like formations — glowing, translucent-looking, and softly exotic.
Onice Bianco Extra captures the luminous, translucent quality of white onyx in porcelain form. The very pale surface glows with gentle grey cloud-like formations that create a dreamy, ethereal quality — as if light were passing through natural onyx. The overall effect is soft, airy, and beautifully luminous without any bold veining or dramatic contrast. Ideal for luxury bathroom walls, feature surfaces, and kitchen islands where a translucent onyx aesthetic adds an exotic, spa-like quality to the space.

"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
