Absolutely, go ahead and wear it! It doesn't mean "marriage" anymore -- it's a beautiful piece of jewelry.

And it's YOURS. i don't know why you even ATTEMPTED to give it back to him because that's NOT what you do when you divorce! Most women sell the ring or keep it to give to their daughters later on. (yes, even in divorce cases). It was yours to KEEP. He should never get it back!!!

So go ahead and wear it with pride -- you designed it, and it sounds beautiful. I'd wear it, for sure!

God bless and take care. Hugs, Lee
