A bail is a component of certain types of jewelry, mostly necklaces, that is used to attach a pendant or stone.[1] The bail is normally placed in the center of the necklace where the pendant hangs.
Some bails are made so a pendant can be attached after the necklace production is completed. This way, a necklace design can be mass-produced for multiple companies and the pendants can be attached after the necklaces are shipped to them.
