Hmmmmmmm.... While I think it's very considerate of you to ask about this, but I don't think it's a question for the general group. If I were you, I'd PM the person who's ring you'd like to re-create. That person's opinion is the only one's who will matter... Personally, I haven't had any custom pieces made, so if someone showed up to the boards with my exact set, I would hardly be upset... I'd be like WooHoo I have a Twinsie! lol However, if I had a ring made that was very special to me in different ways and had a lot of sentimental value attached to the design, maybe I wouldn't want it replicated.
So, not very helpful, lol, but I think you should go straight to the source to ask this question.
