Plain Solid
The whitest white in the Radianz range — crisp, clean, and unmistakably premium for minimalist kitchens.
Diamond White is pure, uninterrupted white — the cleanest surface in the entire Radianz collection with virtually no markings, veining, or colour variation of any kind. This is as close to a perfect blank canvas as engineered quartz gets, with only the subtlest fine grain visible on very close inspection to confirm this is real stone rather than a synthetic material. The polished finish is bright and reflective, bouncing light around the room and making even compact kitchens feel larger and more open. Part of the Radianz Classic collection from LOTTE Chemical, Diamond White is composed of 93% natural quartz bound with polymer resins — the result is a surface that scores Mohs 7 for hardness, absorbs zero water, and resists staining from everything your kitchen can throw at it. The 15-year residential warranty provides long-term confidence. Available in jumbo slab sizes, Diamond White is the definitive choice for ultra-minimalist kitchens, clinical bathrooms, and any space where absolute white purity sets the tone.

"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
