Pietra Di Luserna, also known as Luserna Stone, is a distinctive and versatile natural stone that belongs to the schistose metamorphic rock category, specifically within the gneiss group. This unique stone is characterized by its lamellar-type gneiss structure, where it occurs in superimposed layers, akin to the pages of a book. Quarried in Balma Oro, Luserna San Giovanni, located in the Provincia di Torino, Regione Piemonte of Italy, this stone variety offers a wide range of visual and practical qualities.
The defining feature of Pietra Di Luserna is its layered composition. The rock's formation is characterized by thin, parallel layers that give it its lamellar appearance. This layering creates a visually distinct pattern that varies in thickness, adding to the stone's dynamic aesthetic.
The gneiss group, to which Pietra Di Luserna belongs, is known for its unique combination of mineral grains and layers. The schistose nature of the stone imparts a textured appearance that reflects light in different ways, enhancing its visual interest. The layers of gneiss give the stone a sense of depth and movement, similar to the natural strata found in the Earth's crust.
Pietra Di Luserna's versatile qualities make it suitable for a wide array of design applications. Whether used for flooring, wall cladding, countertops, or outdoor landscaping, it adds a touch of natural elegance and sophistication to any space.
Furthermore, the practical attributes of this stone contribute to its popularity. The layered structure, combined with the inherent durability of gneiss, ensures that Pietra Di Luserna is a resilient and long-lasting material suitable for both interior and exterior installations.
In summary, Pietra Di Luserna, quarried in Balma Oro, Luserna San Giovanni, Provincia di Torino, Regione Piemonte, Italy, is a schistose metamorphic rock within the gneiss group. Its unique layered composition and versatile aesthetic make it a favored option for those seeking to incorporate natural beauty and dynamic texture into their design projects.
With its four marvellous colours Luserna stone is a lamellar gneiss. Due to its enviable technical characteristics, such as its incomparable hardness (even for very thin thickness), it is a versatile material, perfectly suited to every kind of use, both for interiors and exteriors. Thanks to its brightness Luserna stone represents the perfect solution for luxury facing, paving, staircases, and window-stills.
