Set in a textured, hand-forged, yellow-gold setting, the ring's four-carat emerald — sourced from Colombia — is flawless in color and flanked by two diamonds. Berry's husband Olivier Martinez commissioned the one-of-a-kind piece from his Paris neighbor, jeweler Robert Mazlo. The ring reportedly contains codes and symbols in lieu of an inscription, which only its wearer can understand.
