Luckily, their catalogue is on the internet so you can at least have an idea of what you want before you go in. At least I'm hoping everything is in that catalogue!!! You are right about needing a ginormous pendant for the big link necklace, which might be why they show it with 2 "tooth" pendants. I still can't figure out how they attached them though. (it's in the picture on the website). Anyway, I was thinking maybe one of those starfish pendants "Sirene" but they are costly and somehow not something you could wear everyday. I tried one on and it didn't wow me although I absolutely was in love with it in the catalogue. Did you ever try the earrings? I was wondering if they are heavy, but of course that's relative to ones ears, and mine can't take any weight whatsoever. I'm in the US but as my avatar shows, "I'd rather be in Paris"
I'll definitely post when I get in there, even if I walk out empty handed.
