A bola pregnancy necklace is a beautiful piece of jewelry with a special message. According to an old Mexican tradition, a bola pregnancy necklace brings luck, health, and prosperity to the mother and her unborn child. The soft sound of the bell also contributes to a relaxing pregnancy. The unborn baby will recognize the sound as a safe place in the mother's womb. After about five months of pregnancy, the inner ear of the unborn baby is already developed and connected to the nervous system. When the expectant mother/father rolls the bell over the belly, the baby will hear the sound softly and can recognize it after birth. View our selection of Bola pregnancy necklaces below.
