Gold-tone bracelet with crab charm and initials

I found this gold-tone bracelet this afternoon around 2:15 pm behind the Yuma Civic Center on Main Street. It's a slim, about 7 inches long, bracelet with a tiny crab charm and a small turquoise bead near the clasp. The inside of the clasp is engraved with the initials 'A.R.' and there are a few light scratches from wear. It's in decent condition overall; just a bit tarnished from sun. If this belongs to someone, I’d really like to help get it back—looks like it could be sentimental or a gift.
