What is the ruling on the bracelet I found in the outdoor area of the cafe, and no one has asked about it? Should I return it to the cafe owner, or what?

Lost gold items must be publicized by placing advertisements on modern social media or at the café itself, with a general description of the lost items. If someone comes forward and describes them accurately, they should be handed over to him. If no one comes forward after a year of publicizing, it is permissible to take ownership of them. However, if the owner appears after the year and proves his right, then compensation for them is obligatory. As for simple items that are not of concern to the average person, there is no harm in taking them without publicizing them.
