New vintage silver heart puffed engraved hollow pendant charm

New vintage silver heart puffed engraved hollow pendant charm Old fashioned Victorian style. Pretty detailed engraving work on both sides of the heart. Double dash outlines. Diamond cut- like diagonal cuts. Hatch marks on one side. Not too pointy. Soft curves. I’m not sure what it’s a picture of but it’s very shiny and feels organic like leaves and curves. Not too symmetrical or geometric except for the outline / border. C. 10x11 mm + bail and ring I think it’s the perfect size for a charm bracelet or a little pendant to wear everyday. New vintage c. 1980s. Probably handmade in Mexico. No visible hallmarks. But I know it’s silver and it is priced as genuine. Note: polished with vinegar, baking soda and aluminum foil There are bigger silver heart earrings that are a close match.
