Onyx is a semi-precious stone used in high-end kitchens, bathrooms and decorative applications. Its distinctive translucent appearance and banded colour patterns make it one of the most visually dramatic stone choices — and one of the most expensive to replace. Professional repair is essential when onyx is damaged.
About Onyx
Onyx is calcium carbonate — similar in composition to marble but with a distinctive banded appearance and semi-translucent quality when backlit. It is softer than marble, making it more vulnerable to scratching and chipping. It is also very porous and sensitive to acidic substances.
Repairing Onyx
Onyx repair requires specialist transparent or tinted compounds that can replicate the translucent quality of the stone. Our technicians work with a range of compounds suited to onyx repair. The banded pattern is matched as closely as possible through the repair area.
Given the rarity and cost of onyx, we recommend sending photos for a detailed assessment before committing to a repair visit.
