THIS ISN'T MY LIST!!! I DON'T TAKE CREDIT FOR IT!!!
I was looking around the beta forums at WoW.com...and saw a post about how Thorium and Copper are gonna be needed for jewelcrafting 1-300..So i went out and bought 200 bars of each..Then i found this list while searching in google that ppl might like. It contains the other items that will probally be needed...it *IS* beta so this could change..but they probly wont rework the whole prof. (thats my opinion)
Burning Crusade high demand items
November 9th, 2006
It’s no secret that tons of people are going to be leveling their Jewelcrafting skill to 300 very quickly after Burning Crusade gets released. People like new things and of course there is the thrill of being first on your server. That’s why it should be pretty save to assume that the materials required for Jewelcrafting are going to be in an unusually high demand.
In best case scenario you need the following to go 1-300 in Jewelcrafting:
I guess there are plenty of people stocking those already, but there is no reason why you shouldn’t join the crowd so that you can rush your Jewelcrafting to 300 or just sell to wannabe Jewelcrafters once the supplies dry out.
