Georgian era, heart padlock modeled in beautifully detailed 18k gold featuring a foiled/closed back chrysoberyl and locket back with thatched hair (which can be remove by a jeweler if you prefer).
Measures 1.45in in length by 1in wide and 0.48in thick. Central stone measures 11.5mm by 8.9mm and at least 5mm thick based on the depth of the setting. Two of the prongs have been worn down as seen in the photo but stone feels secure. There is a small flea bite to the top corner of the locket which can be seen in the photo. Weight is 7.61 grams.
