The necklace from the Nanàn Bijou collection is in pure 925 silver. As a pendant, a sweet teddy bear hooked onto a wrapped sphere, creating a bundle. The pendant hides inside a mini xylophone on which a small ball dances, which creates a sweet sound while the mother walks or moves to calm and communicate with her baby inside her belly. Wearing the necklace makes this sound familiar to the baby who perceives it as calming, before and after birth. Perfect gift for expectant mothers.
