Perhaps there’s still hope! I too have lost a ring in a garden in Alberta - I went out to rake the leaves with my wedding ring on, and when I came back in I didn’t have the ring.
I got a metal detector, from which I mostly learned that every square foot of that yard has about four pieces of metal it in - I think the dirt came from a construction site at some point, it’s full of old nails and bottle caps and chunks of plaster and whatnot.
