en·hanc·er | in-ˈhan(t)-sər
A type of loop that attaches a pendant or charm to a chain, but has hinges that allow it to be opened and closed
Enhancers are specific types of bails that have hinges that open in the back. These allow the wearer to open and clip a pendant into the middle of a necklace or other piece more easily. With an enhancer, pendants can be easily added to large beaded chains, making it possible to easily transfer pendants between different chains or pieces without requiring work to the piece. This allows more flexibility for jewelry pieces and provides a range of options for those who want to mix and match their pendants with their chains.
