I think a 1/2 ctw Tiffany solitaire in RG would be very elegant. I saw the pics of your rings in your other thread - I know it’s too big/broken, but there’s a lot of finger coverage there. Have you tried on 1/2 ct solitaire? Are you good with a very streamlined look?
Yes I have and the 1/2 size is lovely and comfortable and plenty big imho
