History of the Poison Ring: Vintage poison rings have a long history and originated in ancient India and the Far East, then the mysterious jewelry made its way to Europe in the 16th century. Poison rings – alternately referred to as pillbox, compartment, locket, or vessel rings – also had a benign purpose. During the Middle Ages, they were often used to hide relics of saints, like bits of hair, bone, and teeth, which were thought to protect the wearer from danger. The Renaissance Era brought a new purpose for this jewelry, as the rich would use them to hold sweet fragrances, precious gems, and small momentos like portraits of loved ones, and locks of hair.
