even if they do not carry that designer''s line? I found a Gottlieb & Son''s setting on an internet search which is the exact kind of halo setting I have been looking for. The problem is that none of the jewelers listed within in my zip code are less than 30 miles away. Can jewelers request certain settings even if they do not carry that particular designer''s line if I just want to see it in person or will I be required to buy it?
