The Stone

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

Style:

Plain Natural Polished

Luminous snow-white translucency with the faintest golden whisper — the purest expression of onyx's extraordinary light-transmitting beauty.

White Onyx is onyx distilled to its most essential quality: pure, luminous, translucent light. A pristine snow-white surface with a soft, milky translucency and the faintest whisper of warm golden-amber veining reveals a stone of exquisite, clean-lined minimalism that lets light itself become the primary design element. The polished surface possesses a gentle, cloud-like depth — subtle tonal variations between opaque white and crystalline translucence create an ever-shifting interplay of light and surface that changes throughout the day as ambient light moves across the stone. This is the onyx variety where backlighting achieves its most dramatic transformation. Under ambient light, White Onyx appears as an elegant, understated white surface. Switch on the backlighting, and it becomes a wall or surface of pure radiant light — uniform, warm, and breathtakingly luminous. Quarried in Turkey and Iran, White Onyx represents the ultimate expression of the material's defining quality: its ability to transmit light. In2stone's craftsmen handle this stone with particular reverence, understanding that its minimalist beauty demands flawless fabrication — every edge, every join, every polish must be perfect because the stone's simplicity leaves nowhere to hide.

Frequently Asked

Questions About White

Is White Onyx the most translucent onyx variety?
White Onyx is typically the most uniformly translucent because its lighter composition contains fewer opaque mineral inclusions to block light transmission. The result is a remarkably even, diffuse glow when backlit — the entire surface illuminates consistently rather than in zones, creating a pure wall or surface of warm white light.
How does White Onyx compare to Ivory Onyx?
White Onyx is noticeably cooler and purer in tone, with minimal patterning — just the faintest golden veining against snow-white. Ivory Onyx has more pronounced warm honey banding and a creamier base colour. White Onyx suits ultra-modern, minimalist spaces seeking pristine purity, while Ivory brings more warmth and organic pattern to transitional or classic interiors.
Does the light surface show marks easily?
With any white stone, spills and marks are potentially more visible than on darker surfaces. This makes professional sealing absolutely essential — we apply impregnating sealer at installation and recommend resealing every six months. With diligent care (immediate spill blotting, pH-neutral cleaning, no acidic contact), White Onyx maintains its pristine luminosity beautifully.
What type of backlighting works best with White Onyx?
Warm white LED panels (2700-3000K) produce the most flattering glow, enhancing the stone's natural warmth and making the faint golden veining sing. The panels should be positioned far enough behind the slab for even illumination without hot spots. Dimmable LEDs allow you to adjust the intensity from a subtle ambient glow to a dramatic full illumination.
Can White Onyx be used for a shower wall?
It can create an absolutely spectacular shower wall, but moisture management is critical. In2stone ensures appropriate waterproofing behind the slab and applies professional sealer to the exposed surfaces. The effect of water cascading down backlit White Onyx is genuinely extraordinary — it becomes a wall of luminous white stone with light and water interacting across its surface.
★★★★★
"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!"
