The Lentina Stone is comprised of an intrusive rock (granodiorite), which is similar to granite but is characterized by a greater presence of plagioclase and has a darker appearance. The name derives from the presence of large crystals of potassium feldspars (orthoclase), whose roughly rectangular shape is reminiscent of that of acorns. The rock comes from Val Masino, a side valley of Valtellina, and was carried in a southerly direction down to its present location by the Abduano Glacier.
The Lentina Stone is located approximately 500 metres along the road which descends from Pian Rancio down to Bellagio.
