Art Deco crystal ashtray, potentially designed by Pierre D'Avesn or Pietro Chiesa for Fontana Arte. It is made of thick, aquamarine or green-tinted glass/crystal. The design features an openwork or "scalpellato" (chiselled) edge technique, giving it a distinct geometric, textured appearance. The estimated period of origin is circa 1930s-1940s. It can also be used as a decorative bowl or catchall dish.
