The piece of jewellery was found on the floor on bus station car park in St Ives on Thursday (November 8). It was then handed into Huntingdon police station by a member of the public. A spokesman for Cambridgeshire police said: If you think it might be yours, send us a direct message or call 101 and ask to be put through to Huntingdon police station. You will need to show proof it belongs to you.
