Pendant: 11mm x 17mm

The wishbone is a lucky symbol. The tradition goes that as two people try to break it apart, each person makes a wish and whoever is left with the larger part of the bone once it has been broken will have their wish granted.
All of the chain lengths are shown photographed on male and female mannequins to give an idea of where they will sit (although this is just a guide, it will depend on your height and neck size).
