Here you will find all the components to personalize your custom hidden message necklace. Just like the Add-a-Bead Necklace of the 90's and the iconic charm bracelet, this necklace can be built over time. Pendant "charms" can be added or removed from the cleverly designed "stringer" chain (get it?). Mix & match metals, gemstone colors and pendant lengths too. Start creating your truly unique piece of jewelry with these components.
