Dont lose hope. My mum lost her engagement ring as well about a year ago after 25yrs of marriage. She was devestated. It was more the sentimental meaning behind the ring and that she wouldnt have 'that' ring.

They ended up getting a jeweller to do a replica of it and it was amazing and then 6months later, the ring turned up and it was in those loopy holes in the spare tyre. She went through her car with dad 4 times and nothing and then she put it in to be detailed as they were selling it and the detailer found it!!!!! Anyway a bit of a side track but wanted to let you know a possible good outcome.

I really think the car still or on the path between your car and your house as you weer taking in groceries.

I think you would have noticed it was missing when you were strapping DD into her car seat if you had lost it at the shops as that is something fiddly with your hands.

it will turn up for you
