The Stone
See the natural beauty of Cosmic Grey up close — the surface texture, colour depth, and veining that make this quartzite unique.
From Brazil, Cosmic Grey quartzite evokes stormy seascapes with its deeply atmospheric dark grey and charcoal wave-like patterns.
Cosmic Grey quartzite offers a deeply atmospheric presence, drawing you into its rich, dark slate-grey and charcoal tones. Across its surface, flowing, wave-like formations create a powerful, oceanic movement, as if gazing upon stormy seascapes. These layered, undulating grey-black patterns deliver remarkable natural drama and visual depth, making Cosmic Grey a truly commanding choice for luxury worktops that desire a moody, contemporary sophistication.
Quarried in Brazil, Cosmic Grey is a true quartzite, born from quartz-rich sandstone transformed deep within the Earth's crust. Under immense heat and pressure, its individual quartz grains recrystallised into an interlocking mosaic, resulting in one of nature's hardest and most durable materials. This incredible geological journey gives Cosmic Grey its exceptional Mohs 7 hardness, ensuring a worktop that stands up to the rigours of daily life.
At In2Stone, we believe a worktop should be as practical as it is beautiful. Cosmic Grey is not only stunning, but also exceptionally hard-wearing, demonstrating excellent scratch, heat, and acid resistance. While it's naturally low in porosity, as with all natural stone, we'll guide you on simple sealing and care to maintain its pristine look for decades. Our passion for craftsmanship means every slab, from hand-templating to the final expert installation, reflects our dedication to creating luxury results with honest pricing. Choosing Cosmic Grey means inviting a piece of geological artistry into your home.

"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
