The Stone
See the natural beauty of Diamond Onice Grigio up close — the surface texture, colour depth, and veining that make this porcelain unique.
Cool grey with translucent onyx-effect banding in blue-grey, silver, and copper — a mesmerising, jewel-like surface.
Laminam Diamond Onice Grigio captures the translucent, layered beauty of natural onyx in a porcelain surface of extraordinary visual complexity. A pale cool grey base carries flowing, translucent-looking banding in blue-grey, silver, and white tones, accented by unexpected warm copper and rust highlights that add depth and contrast. The layered, banded pattern has a genuinely translucent quality — as though light could pass through the surface — creating a mesmerising visual effect unlike any other marble or stone-effect porcelain. Part of the Diamond collection, Onice Grigio is designed for homeowners who want a surface that feels genuinely precious and one-of-a-kind. A statement of extraordinary beauty.

"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
