This locality is said to have produced the finest Italian amethyst specimens.

The Capurru quarry, located on the outskirts of Osilo, is the best-known and today best-preserved extraction plant in the area: the imposing and characteristic tower of the central plant, on which some rusty machinery still remains, is visible even from long distances. Organized on two levels, it produced gravel for embankments and roadbeds. It was abandoned some decades ago.
