Golden pregnancy bola with a pendant ball containing a small bead. The pregnancy bola is a piece of jewelry originating from Indonesia. According to tradition, it is given from the first weeks of pregnancy and represents a good luck charm for the pregnant woman and her future baby. It takes the form of a necklace composed of a long chain and a pendant in the shape of a ball inside which a bead, with each movement of the expectant mother, emits a very soft and characteristic sound. Its positive vibrations, both soothing and relaxing, are perceived by the fetus from the beginning of the 4th month of pregnancy. At birth, the baby will recognize this sound which will soothe them.
