VINTAGE 3D BROOCH WITH WORKING LOCKET, HEARTS, & BUTTONS - NO PIN

Vintage 3D brooch with working locket, hearts, and buttons. Set on a gold tone filagree circle. The locket has a white center that looks handprinted with a pink flower and green leaves. The locket opens. Some of the hearts have metal studs or stones and a burnished effect. I can't be 100% sure if it's slightly rusted on purpose. There are hearts with carved designs. Some of those are silver tone and some are gold tone. There are assorted pieces that look like buttons or decorative discs. The pin on back is missing. I think it could be easily added. In good preowned condition. 2.25" Diameter .5" High (approximately) I am decluttering my late grandmother's collection.
