Ok, we finally got the Jewelcrafting materials list up on Crafter's Tome for you:
Jewelcrafting 1-300 Materials
I also went ahead and compiled a power-leveling guide for Jewelcrafting, while I was at it. You can find the skill guide at:
Jewelcrafting Guide for 1-300
Enjoy folks and let me know if you have any questions, comments, or find a problem with either listing.
