Dazzling Victorian diamond locket.
Modelled as a central domed glass locket centre, with undulating diamond set border (old cuts and rose cuts) the diamonds set in silver and backed with 18 carat gold. (closed back)
The back of the glass central locket hinges open and I have removed the hair and added some loose diamonds. 
It's so pretty  and feminine
