Droffers and Son Salvage aren't smart enough to restore the magic in the necklace, but I am.  All I want to do is study the necklace so I can learn to make them myself.  To do that, I will need your necklace.  Let me borrow it, and in exchange for the time I get to study it I will translate the journal for you.  While you are searching for the gems, I should have enough time to learn what I need to.$B$BIt's a simple deal, and no one else will be the wiser.  Whatcha wanna do?
