The Stone

See the natural beauty of Super White up close — the surface texture, colour depth, and veining that make this quartzite unique.

Pristine white luminosity with delicate frost-like mineral clusters — the purest expression of quartzite elegance.

Super White Quartzite is a stone that has earned its superlative name. Its bright, cool white base glows with a pristine luminosity, while scattered clusters of soft grey mineral formations and fine, delicate veining create a subtly textured, frost-like quality that prevents it from ever feeling sterile or artificial. This is white at its most refined — a balance of purity and natural detail that no engineered surface has yet managed to replicate. Technically classified as a dolomitic quartzite — carrying properties of both marble and quartzite — Super White has earned a remarkable reputation in the stone industry for its exceptional Mohs 8 hardness, which places it among the hardest natural stone surfaces available for worktop applications. It is essentially non-porous, highly resistant to scratching and etching, and available in polished, honed, leathered, and brushed finishes. This combination of near-pure aesthetic and extreme durability has made it one of the most specified natural white stones by architects and interior designers worldwide. In2stone considers Super White the gold standard for clients who want nature's purest white stone without sacrificing an ounce of practicality. Its cool, clean character pairs perfectly with both warm and cool design palettes — work it with warm timber and brass for a natural warmth, or with grey tones and polished chrome for a crisply contemporary look. Our master stonemasons bring decades of experience to every Super White installation, ensuring invisible joins, precise edge profiles, and a finish that lets this extraordinary stone speak for itself.

Frequently Asked

Questions About Super White

What makes Super White quartzite so special?
Super White quartzite stands out for three exceptional qualities: its pristine, cool white base that rivals the purest marbles; its extraordinary Mohs 8 hardness — among the hardest natural stone surfaces available; and its practically non-porous nature that delivers outstanding stain resistance. Technically a dolomitic quartzite with properties of both marble and quartzite, it offers beauty and performance in a combination that no other natural white stone can match.
Is Super White quartzite actually quartzite or marble?
Super White is technically classified as a dolomitic quartzite — a geological hybrid that carries properties of both marble and quartzite. Its mineral composition includes both quartz and dolomite crystals. Crucially, it performs far more like quartzite than marble: its Mohs 8 hardness significantly exceeds marble (3-5), it does not etch from acidic foods and drinks, and it is essentially non-porous. In practical terms, it offers the visual purity of marble with the rugged durability of quartzite.
What finishes are available for Super White quartzite?
Super White quartzite is available in four finishes to suit different design preferences. Polished delivers a high-gloss mirror finish that maximises the stone's pristine white luminosity. Honed provides a smooth, satin surface that hides fingerprints and minor marks. Leathered creates a tactile, textured surface with organic warmth. Brushed offers a subtle directional texture. Each finish changes the stone's character meaningfully — we recommend viewing physical samples at an In2stone consultation.
How does Super White quartzite compare to engineered white quartz?
Super White quartzite outperforms engineered white quartz in several key areas: it is significantly harder (Mohs 8 vs 7), completely UV-stable (will not yellow in sunlight), heat-proof (handles hot pans directly), and entirely natural with unique patterns in every slab. Engineered quartz offers more consistent patterning and potentially lower maintenance, but cannot match the depth, character, and one-of-a-kind beauty of a natural stone like Super White. For many discerning homeowners, there is simply no substitute for the real thing.
Does Super White quartzite need much maintenance?
Super White quartzite requires very little maintenance. Its practically non-porous nature means spills sit on the surface rather than being absorbed. Daily cleaning with warm water and pH-neutral soap is all that's needed. Annual sealing with a quality impregnating sealer provides an additional protective layer. Its Mohs 8 hardness means it resists scratching from everyday use. Of all natural White stones, Super White is among the most effortless to maintain — a genuine low-maintenance luxury.
★★★★★
"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!"
