Marmo Onici: Complete Guide
Marmo Onici is a natural stone prized for its understated elegance and versatility in architecture. Discover its characteristics, recommended uses, and maintenance tips.
History and origin
Marmo Onici comes from quarries located in the Veneto region of Italy, where the geological formation dates back to the Triassic period. Extracted from blocks of metamorphosed limestone, the material has a usage history that spans from classical architecture to contemporary projects, thanks to its ability to combine robustness and aesthetic beauty. The Onici quarries have been operating since the 19th century, ensuring a steady supply for premium cladding and furnishings.
Look and veining
Marmo Onici features a light gray base with thin, irregular veins of darker tones, ranging from anthracite gray to brown. Its variants include more uniform versions and others with more pronounced markings, offering options for both minimalist spaces and more rustic designs.

Recommended uses
Marmo Onici is ideal for flooring, wall cladding, kitchen and bathroom countertops, thanks to its mechanical resistance and elegant appearance. It is less suitable for surfaces frequently exposed to aggressive acids, such as laboratory worktops, or for untreated outdoor areas where intense freeze exposure occurs without proper protection.
Care and maintenance
To preserve its original look, it is recommended to clean Marmo Onici with warm water and neutral detergents, avoiding acidic or abrasive products. Periodic sealing, every 12-24 months, protects against stains and liquid penetration. In case of stains, act quickly with a soft cloth and, if necessary, a stone‑specific cleaner.
