Charming Georgian gold egg perhaps from a Chatelaine, with a white band of enamel and in it the motto ‘Gage de Mon Amitie’ - token of my friendship. The egg unscrews to reveal an empty interior that can hold a token. 
The gold is decorated with an embossed pattern. 
A gold bolt is attached to the bale.
