Before anything else, put a mask on. The water here is clear, and a ring that came off on the rocks may be lying in a crack you can see from the surface.
Then tell the beach bar, the lifeguard and your reception. If you leave soon, post a request before you go.
Istria has very little sand. Most of the coast is flat rock, concrete bathing platforms and small pebble coves. The sandy exceptions are few: Bijeca in Medulin, and a couple of small bays on the Kamenjak peninsula.
Under Croatian law, whoever finds a lost item has to return it to the owner if they can tell whose it is. Otherwise it goes to the nearest lost-property office, handed in by the finder or by whoever owns the place where it was found. That is why the reception, the campsite and the beach bar matter: a ring found on their beach often passes through their hands first.
The owner then has a year from the office's public notice to claim it (Croatian property law, articles 134 to 136).
That office is the police station itself: Croatian law hands the lost-property office's duties to the police (Zakon o vlasništvu, article 392), and in Istria that means the station in Umag, Poreč, Rovinj or Pula, whichever is nearest. Wherever you go, leave a description, a photo of the ring if you have one, and a number that still works once you are home.
Croatia's heritage law bans using a metal detector anywhere in the country, underwater included, to look for archaeological finds, and there is no permit a private person can get (Article 37).
The ban is tied to what you are looking for, and yesterday's ring is not what it names. That does not make it a permission, and much of this coast and seabed is registered as archaeological zones. Whoever holds the detector is responsible for knowing the rules and keeping to them. Retrievly does not check. Anything old that turns up stays where it is.
The full picture: Is metal detecting legal in Croatia?.
Do three things while you are still here: pin the exact spot, tell the people who run that beach, and post the request while you can still describe the place clearly. What to do before you fly home has the rest.
You do not need to go back. The beach, the nearest ladder or bar, and the day are enough for someone to start.
Retrievly does not search. It puts you in touch with people who own a detector and will go out and look.
We are new in Istria, so there may be nobody signed up near your beach yet. Then we go and find someone: you post the request, we ask around the detecting groups in the region and send them the link.
Only a rough circle is shown in public. The exact spot goes to the one person you pick.
No money goes through Retrievly. A thank-you, if you want to give one, is between you and whoever goes out.
Post soon and draw the circle tight: those two decide it more than anything else. Retrievly vets nobody, so meet in daylight, somewhere public.

Kenny built Retrievly. He has snorkelled the Danube for years and keeps bringing up things that belong to other people: wallets with the ID still in them, phones, keys. That is where Retrievly came from.
