9ct hand-engraved heart shaped padlock closure measures 1" tall and 5/8" wide, closes securely. c. first half of the 20th century. I added a high-quality gold fill fragment of a watch chain, super heavy graduated curb - c. 1900. The color match is damn near perfect. I almost always find these "locks" without their original chains, but they were usually used to secure bracelets that looked like this. Measures 7".
