Iragna is a premium granite sourced from Switzerland, renowned for its elegant grey hue and subtle, evenly distributed veining that adds depth without overpowering the stone’s natural beauty. The grain is fine to medium, offering a smooth surface that is ideal for both polished and honed finishes. Architects and designers favor Iragna for high-traffic floors, countertops, and wall cladding, as its durability and resistance to abrasion make it suitable for both indoor and outdoor applications. Marmi di Carrara supplies Iragna in large blocks, ready-to-cut slabs of 2–3 cm thickness, and custom-cut pieces, with detailed photographs of actual slabs available before purchase to ensure precise selection.

Iragna Gneiss: complete guide
Overview
Iragna Gneiss is a grey stone from the canton of Ticino, compact and with a slightly oriented structure. It is a traditional stone for floors, stairs and outdoor areas.
History and origin
It takes its name from Iragna, a village in the Riviera district of Ticino, an area where gneisses well known in Switzerland and Northern Italy are quarried. These stones have been used for centuries for paving, steps, walls and roofing in Alpine buildings. Today they are also used in contemporary architecture. Marmi di Carrara supplies it on request.
Appearance
The background is grey, with light quartz and feldspar crystals and dark mica arranged in thin bands. The pattern is more veined or more speckled depending on the cutting direction and varies slightly between slabs. Honed, it looks an even, understated grey; flamed or natural split, it has a rustic effect.
Uses
Suitable for outdoor paving, stairs, walls, cladding, kitchen worktops and interior floors. It withstands frost well, so it is suitable for mountain areas. Split finishes are ideal for gardens and paths, less so for interiors, where a honed surface is preferred.
Care and maintenance
Clean with water and a neutral detergent. Outdoors, periodically remove moss and leaves to prevent stains. A water repellent is useful on more porous or split surfaces.
