Poison ring

Ring with concealed compartment which could be used to store poison

A poison ring or pillbox ring is a type of ring with a container under the bezel or inside the bezel itself which could be used to hold poison or another substance; they became popular in Western Europe during the Middle Ages. The poison ring was used to slip poison into an enemy's food or drink. A powder or liquid poison was stored in these instances. In other cases, the poison ring was used to facilitate the suicide of the wearer in order to preclude capture or torture. People more commonly died from suicide rather than murder caused by the poison ring. The purpose of the compartment in the ring was not only limited to poison. Rings with such compartments were long before used for other reasons, before, during, and after the peak of poison rings.
