Victorian era, cabochon turquoise heart padlock set in silver with a 15k gold back and central locket compartment.
Measures 1.25in in length by 0.8in in width and 0.5in thick including locket compartment. Locket compartment is 7.2mm in diameter and is currently empty (would need to be removed by a jeweler if you’d like to add something to it). Some turquoise cabochons are more worn than others which is commensurate with its age and visible in the photos. Weight is 6.47 grams.
