How can a gold ring found in a resort far from the original place of residence be defined, given that most of the resort's inhabitants are expatriates, and the finder has returned to his home country?

This ring is considered a lost item (Luqata), and it must be publicly announced for a full lunar year in the place where it was found, in gatherings of people, and in areas frequented by vacationers. You are not required to make the announcement yourself; you can delegate it to someone you trust. After the year has passed, you may dispose of it, while guaranteeing its value to its owner should they be identified later.
