One unlucky spouse may not be too popular with their other half right now after apparently misplacing their wedding ring in a car that had been hired out.

A Queensland Police Service spokeswoman said the ring was found last Thursday (January 15) in a northbound hire car travelling to Cairns.

The wedding band has the date May 16, 2015, engraved on the inside, as well as a circular indentation on the outside of the simple silver-coloured design.

The rightful owner will need to show identification and proof of ownership to claim the ring.
