This is a charming curiosity, it's a rare vintage gold Pizza Oven in 14ct gold that opens to show the Baker standing with his pizza peel (paddle). 
 
To the outside there is a rose-gold gilding to the brickwork on the oven door, and round the side a charming bench seat with two hearts, presumably where courting couples might sit & enjoy their fresh pizza.
 
To the inside there's a kitchen counter and the oven with chimney.  There are still traces of the original enamel to the baker and the inside oven, however much has been lost with age.  The oven door closes securely with a twist of 'dough'.
 
This charm is unmarked and tests as 14ct gold. It comes with a jump ring ready to attach to your bracelet.
