I have a halo setting for my Ering that was designed by ERD. the shank is 2 pointers, so I believe the band is about 2mm. The ring was made 2 years ago, but because it took 3 tries to get it done somewhat correctly I was turned off to working on a wedding band at the time. Well fast forward to now, it is really time to get a band. I am still trying to avoid going custom as I don't have a trusted jeweler in the area and ERD is too far to make a trip. I saw a really nice one on blue nile (platinum, u pave) and its reasonably priced (around 2K with their current promotion) . However, it is about 2.4MM. Is there a significant visual difference between 2 mm and 2.4? What are your thoughts or recommendations?
