I am IN LOVE with Tiffany's Lucida & with my boyfriend of course. I don't really want to break him though. Does anyone know where else to get something similar to the platinum Lucida that Tiffany's has? I think they use a special cut diamond for it also but I am not sure. Is it Princess or Radiant or something special to them? Keep in mind that I really don't know what I am talking about, still learning! Thanks.
