The Stone
See the natural beauty of White Onyx up close — the surface texture, colour depth, and veining that make this quartz unique.
A serene warm white quartz featuring subtle, watercolour-like lighter patches and a tone-on-tone mottled pattern, creating a delicate onyx-like translucent effect perfect for tranquil spaces.
White Onyx is where subtle elegance meets enduring quality. We love how this Modern Quartz Stone surface begins with a beautiful warm white/cream base, then reveals its unique character through a delicate, tone-on-tone mottled pattern. Look closer, and you’ll see organic, watercolour-like lighter patches gently emerge across the surface, giving it a soft, almost translucent depth reminiscent of natural onyx. The polished finish enhances this luminous quality, making your worktop feel both luxurious and inviting.
As craftsmen, we ensure every installation of White Onyx is precise and beautiful. From careful hand-templating to meticulous joins, we bring your vision to life with skill. Beyond its stunning appearance, this engineered quartz offers exceptional practicality. It’s wonderfully non-porous and remarkably easy to care for, meaning no sealing is ever required and a simple wipe is all it takes to keep it looking pristine. Highly resistant to daily scratches and stains, it’s built to stand the test of time in even the busiest homes.
Imagine White Onyx gracing your kitchen as a sophisticated worktop, a serene island centrepiece, or extending seamlessly up as an elegant splashback. It’s equally at home transforming a bathroom into a spa-like retreat, offering a sense of calm and understated luxury that complements a wide range of interior styles, from contemporary minimalist to classic traditional.

"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
