Throughout SOA, it think there are the Beljurils. I can't think off all the locations but i know where one is.
Go to the Umar Hills and talk to the farmer next to the creek in the village. Pay to hear his story about the chickens. Head over to the owners of the chickens and question them, ultimitley making them confess. Choose how you get the chicken, but the gem found is a Beljuril. Good luck.
I think the Fixpack prevents you from getting the berjuril through pickpocketing. Something does, anyway, cause I couldn't do it on my game.
There is a 2nd berjuril available somewhere, though I'm not sure exactly where. If I had to guess offhand, I'd say it's in the Windspear Hills/Firkaarg area.
Yep, positive on Windspear Hills/Firkaarg, turn right(up on map) before the werewolf ambush, look for the three guys in dispute, locate hidden door, beat golems, look in niche; done
