I found gold in my apartment laundry place.(someones ear ring) but it is just one peice. what shall i do with it. give it to apartment or post note for lost and found. Legally is it mine now since I found it or I might get into legal trouble for few dollars.I kept it because how do I know who is the owner now.
Suggestion please. 

 Mitra, arkako sampati ma k lov garchhau yaar.....Apt office ma deu, notice tasa...j garera hunchha let the ring reach back to its owner......Ma pani khus, ring owner pani khus!
