Is it useful to call the police when the diamond ring is left in the hotel room?

If the diamond ring is lost after being left in the hotel room, it is useful to call the police. First of all, you should contact the front desk of the hotel as soon as possible, explain the situation and ask to investigate the surveillance video. If the video shows that someone has entered your room or found a diamond ring, you can report it to the police and provide relevant evidence and clues.

Although the diamond ring itself is very valuable, if there is not enough evidence to prove that the hotel staff stole the diamond ring, the police may not solve the problem immediately. In this case, you may need to consider negotiating with the hotel or seeking legal assistance.

In short, if you find valuables missing, you should take timely action, seek help and keep relevant evidence.
