HB,
Had I known you were going to get a setting there as well as setting a stone, I would have warned you against getting it set there. The benchmen there are in a huge hurry since they have several other projects being done at the same time as yours. They just do not have the time or the concern about doing a good job. Also, you have to be really careful about setting stones simply because they will easily chip them. Whenever I get a stone set, I go to a jeweler that takes their time and is very careful with my stones. At intergem, that simply is not possible.
I also always go by myself to these shows. It's more fun that way because you don't have someone riding your tails trying to get you to hurry up. You can go at your own pace. I haven't gone in years because #1) I have small children and I can't "escape" the house for more than 8 hours (that's how much time I'd like to spend there) and #2) last time I went, it was all fake designer handbags and ugly clothes. There was very little in the way of fine gems and jewelry. There was some, but not as much as a grand show like Tuscon (from what I hear).
In any case, I hope you get your setting fixed, and also make sure your jeweler inspects your stone for damage.
