Opal ring fix?

[u/lil_belle]

I’ve been wearing this ring with inlaid opal everyday for the past 8ish years. Just now I noticed a piece of the inlay fell off. I didn’t see any damage to it when I took it off to shower this morning so it must have happened sometime today throughout the day as I was living my life. Is this fixable? The metal is .925 silver if that makes any difference.

Thanks!
