It seems like there''s a lot of information here about how to get great deals on stones, but I''m wondering if anyone has any tips or advice for finding a good deal on a setting? Is it generally cheaper or more expensive to have a setting custom made? I know there can be a tremendous mark-up on designer settings, but even for no-name versions it seems like the prices are often quite high. We looked yesterday at a lovely platinum 3-stone setting w/ side pears (approx .5 tcw) that was selling for $3,600 at a reputable DC store. That seems high to me, or am I being unrealistic? Any advice? Our challenge is that we would need a finished product very quickly (i.e. within 2 weeks). thx!
