New vintage silver 925 heart hollow engraved puffed charm pendant

New vintage silver 925 heart hollow engraved puffed charm pendant Old fashioned Victorian style. But with curvy top and pointy bottom that looks more modern to me. Pretty detailed engraving work on both sides of the heart. Double dash outlines. Diamond cut- like diagonal cuts. Hatch marks on one side. Very shiny. Engraving enhances and decorates the heart shape. Not too symmetrical or geometric except for the outline / border. C. 15x15 mm + 2x7 bail I think it’s the perfect size for a pendant to wear everyday or as an slightly oversized charm on a bracelet. New vintage c. 1980s. Probably handmade in Mexico. Hallmark: 925. Note: polished with vinegar, baking soda and aluminum foil There are silver heart earrings that are a close match.
