Try the salad drawer in the fridge. My friend found her engagement ring in her salad drawer, but her wedding ring has yet to materialise. 
I didn’t think to look in the salad drawer when I lost my engagement ring and wedding ring years ago.
When my daughter lost her wedding and engagement rings a few years ago, my husband went through her kitchen bin, and there they were.
She’s getting divorced now, because he was controlling and abusive. She threw her wedding ring in the river, she was so distressed.
Incidentally I have got replacement rings now. In fact, my husband upgraded my second engagement ring about five years ago again, and we went together to Hatton Garden to choose the diamond. The same jeweller who made the new ring made my second diamond into a diamond pendant for my daughter.
