Big 2.5” Filigree brooch has a hinged center locket compartment to hold a secret or photo or lock of hair. It may have held solid perfume at one time. The filigree has a vintage gold plating and there is an amber stone in the top of the locket door. There is also a bale at the back so you can wear it as a pendant which I think would look pretty cool and boho. Either way, it’s really neat.
