that's a lovely idea. op you could gift yourself with a birthstone or just a beautiful colored stone you admire and it'll have lots of meaning without jumping out at others as engagement-y. good luckAfter reading your thread, two things stuck out to me: 1) the ring doesn't feel "right" to you or your SO and 2) you and your SO love each other and want to stay together, marriage or not. IMO I'd reset your diamond with a colored stone as a toi et moi (à la Jackie Kennedy) ring. You could pick something delicious like a forest green tsavorite garnet (and not too expensive, to boot!) to pair with it. I think the sentimentality of "you and me" could be so apt for your relationship. And if your in-laws are squawking at you about it, you can just say that you bought the ring originally, and then COVID happened, and it just didn't feel the same anymore. As a bonus, sourcing a gemstone and resetting will take some time, and perhaps your SO will change his mind on presenting you with a ring once some progress is made on the divorce and it feels more "real" to him.
