Founded by master craftsmen with decades of experience in pen production, Gioia has quickly gained a reputation for producing innovative, unusual, and deeply beautiful writing instruments. The Cameo, with its hand-engraved cap top, serves as an exemplary showcase of the Gioia approach.

The art of cameo processing developed in Naples in the area of ​​Torre del Greco together with that of coral. Cameos, with three or four layers of agate color and a metamorphic image, which includes several subjects, can be incredibly valuable. Furthermore, cameos carved in colored stones like opal, lapis, and emerald are rare and highly valued.
