I want to learn jewelry processing by myself and go to Quel Dahners Island to buy drawings. The NPC next to the innkeeper sells them. NPC can also trade brands for raw materials. The raw material for 6 wounds and 5 quick wounds is called burning stone. Team FB will drop. If you are not a jeweler, you can find a jeweler to cut it, but some people may not buy drawing, so they won't. Some people will cut it when they buy drawing, which is probably why you didn't find it in jewelry processing.
