Silver ring with emerald stone, found near Bath.

I found a silver ring this afternoon around 2:15pm, on the pavement outside the Royal Crescent shops in Bath. It’s a sterling silver band, UK size N, with a small emerald bezel setting. The outer surface is slightly worn, and there’s a tiny engraving on the inside—'LJ'—that might help identify the owner. I know rings can be sentimental pieces, and I’d love to get this back to whoever lost it.
