| Hi,
I would go as long as you can afford to and try to get the necklace made with invisible clasps that will allow your wife to break it down into a number of necklace and bracelet combination... like a whole pearl wardrobe in one long necklace!
As far as size, I think smaller (7-8 mm) pearls look great, especially in an opera length. If she is planning on wearing these every day, especially.
Good luck, |
