Antique locket. 

Locket appears to have a gold gilt finish but the finish is worn.

Not hallmarked.

Blank car-touche to the cover.

Top loop has a small gap in it so it can be opened to fit on a chain link. 

Inside is roughly finish but would have been covered over by the photos in the locket.

Locket is approximately 30mm wide and 40mm high (top of the locket not the loop).

General aged wear, well looked after.
