also known as Luserna Stone, Luserna Gneiss, Losas de Luserna
A micaceous gneiss from the Cottian Alps of Piedmont, quarried around Luserna San Giovanni. Pietra di Luserna offers a fine silver-grey tone and an exceptionally consistent natural split surface — it naturally cleaves into smooth, flat slabs ideal for paving. It has been a benchmark stone for Italian garden terraces, pool decks, and alpine residential facades for decades.
Type-level physical facts shown. Per-lot lab values (absorption, flexural strength) confirmed at quotation.
Yes — its internal foliation allows it to split into thin, remarkably flat and consistent slabs without machining, making it an efficient flagstone for exterior terraces and garden paths.
Excellent. Luserna gneiss has very low water absorption and high freeze-thaw resistance — it has been used for alpine facades and terraces in sub-zero environments for generations.
