I think I'd probably wear it B, but it's a gorgeous ring, and it doesn't lose anything either way! Wear it whichever way you'd like!

Is it engagement or wedding band. It looks like it has a spot for the diamond engagement ring to inset on it. If so it would be wedding band on inside and engagement ring on outside. So B. But if you are wearing the ring alone you could really wear it whichever way you want.

Depends what kind of ring it is engagement or wedding ring because another ring would be work with it, if wearing it on its own then it's ur personal choice
