So, I just got my setting remade and asked to get it as close to the Tiffany Oval Soleste as possible. The jeweler did a great job other than the fact that there is a visible gap between the halo and the center stone. He told me that this is impossible to avoid, and that this gap is "as small as humanly possible". I can't imagine that this is the truth, considering of the ring at the actual Tiffany store has no noticeable gap that I can see with the naked eye. I will attach pictures, and please let me know your thoughts!!
