So basicly this is where you craft jewlery and resell it for profit.
Rate 1-10: 8
Firstly, buy gold from the grand exchange (400+ gives most profit)
You can get there by taking the path in lumbridge by the goblin area.
Secondly, go to edgeville ( west from grand exchange)
go to the furnace and craft either a braclet *members, or a necklace.
NOTE: Necklace needs a necklace mould and lvl 6 of crafting. (same for bracelet)
You can train crafting by cutting opals (and they do make a profit if you succsessfuly cut it)
When all of you gold is crafted, go to the bank and fill your inventory back up with gold bars
when you're done, go sell the crafted stuff. Here is the profits for this.
