Woo-hoo, how fun! I just went through the same search and ultimately ended up getting my stones and settings from Wink Jones, but if I had to choose off the rack, I like the WF martini studs the most. James Allen''s website says that theirs are handmade, which is somewhat alluring too. Good luck and keep us posted.
Thanks! I wanted something dainty and small, and I think I''m leaning towards WF but I saw James Allen''s and didn''t know if anyone had purchased them. My DH wants to "surprise" me with them... as he would leave the non off the rack purchases to me.
