Terrazzo Exotic Polished

Bold onyx fragments embedded in clean white — a contemporary mosaic where each stone piece reveals its own hidden universe of colour.

Terrazzo Onyx bridges the gap between ancient craft and contemporary design: a clean white cementitious base is embedded with large, irregularly shaped onyx aggregate pieces in muted green, grey, amber, and translucent tones, creating a bold mosaic aesthetic where each chunky stone fragment reveals its own unique internal banding and coloration. This is the most architecturally modern onyx variety, trading the flowing, organic formations of traditional onyx for something geometric, deliberate, and unapologetically contemporary. Yet each embedded fragment retains all the translucency and mineralogical beauty of its parent material — hold a light behind this stone and each piece glows individually, creating a constellation of illuminated fragments within the white matrix. Quarried and assembled in Turkey, Terrazzo Onyx appeals to designers seeking the luxury and translucency of onyx within a boldly contemporary visual framework. In2stone's fabricators appreciate the dual challenge this stone presents — cutting cleanly through both the cementitious base and the embedded aggregates requires specialist tooling and a patient, precision approach our craftsmen have refined through years of working with the most demanding natural materials.

Frequently Asked

Questions About Terrazzo

Is Terrazzo Onyx actually onyx?
It contains genuine onyx. Each of the large, irregularly shaped fragments embedded in the white base is a piece of translucent banded calcite onyx. These chunks retain all the translucency, banding, and mineralogical character of solid onyx slabs. The white cementitious matrix binds them together in a terrazzo-style composition, creating a unique hybrid of traditional craft and natural stone luxury.
Can Terrazzo Onyx be backlit?
Yes, and the effect is unique among onyx varieties. Rather than a uniform glow, each embedded onyx fragment illuminates individually — some glowing green, others amber or translucent white — creating a constellation-like effect of separate luminous pieces within the white matrix. It is a distinctly contemporary take on onyx backlighting.
How does Terrazzo Onyx compare in durability to solid onyx?
The cementitious matrix provides some additional structural resilience compared to solid onyx, but the surface care requirements are similar. The onyx fragments are still soft calcite (Mohs 3-4) and acid-sensitive, so the same sealing, cleaning, and protection protocols apply. Treat it with the same care you would give any onyx surface.
What design styles suit Terrazzo Onyx?
Terrazzo Onyx sits most naturally in contemporary, mid-century modern, and Art Deco-inspired interiors. The geometric, fragmented pattern works beautifully alongside clean-lined cabinetry, terrazzo flooring, and modern metalwork. It creates a visual dialogue with traditional terrazzo while adding the unique dimension of onyx translucency.
Is each slab of Terrazzo Onyx unique?
Absolutely. The size, shape, colour, and distribution of the embedded onyx fragments varies between every slab. Some may feature predominantly green pieces, others more amber or grey. This natural variability means your specific slab will have its own distinct composition — another reason we encourage clients to view and select their slab in person.
★★★★★
"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!"
