This heart-shaped padlock pendant combines luxury with ingenious functionality. Select from 18k rose gold with rubies, 18k yellow gold with blue sapphires, or 18k white gold with rubies, each adorned with white diamonds. The included 18k diamond-cut anchor chain measures 2.2mm. The dual-dial mechanism employs colored gemstones as your personal security code—align them with the front diamond markers to release the pendant, then attach to any chain. Secure it by realigning the stones and pressing the arch closed. Rotate the dials to randomize your code and keep the pendant locked throughout wear.
