Portoro

Portoro is an extraordinarily dramatic Italian marble that captivates with its intense black base, a rich canvas that provides the perfect backdrop for its opulent patterns. Across this deep, dark surface, a magnificent, fractured network of rich, glowing gold veining intertwines with delicate white veins, creating a spectacularly luxurious, high-contrast pattern. The highly polished finish enhances this interplay of jet black with opulent gold, lending a wonderfully classic and regal quality to any space.

Quarried exclusively from the historic region of Porto Venere in Liguria, Italy, Portoro's prestigious heritage is etched into its very stone. Like all marbles, it's a non-foliated metamorphic rock, formed when ancient limestone undergoes immense heat and pressure, causing its calcite crystals to recrystallise. The distinctive black colour and the stunning gold and white mineral inclusions are a unique signature of this specific geological formation, creating a material unlike any other.

When we select Portoro for your home, we're choosing an iconic material destined to become a breathtaking centrepiece. While its highly polished surface is naturally resilient, as a calcite-based marble, it appreciates a little care – regular sealing helps protect against spills, and we always advise being mindful of acidic liquids. We hand-template every piece, ensuring those magnificent veins flow seamlessly across your worktops, splashbacks, or feature walls. With In2Stone, you get not just an exceptional material, but the passionate craftsmanship to bring its full, opulent beauty to life in your kitchen or bathroom.
