Hiril Manadhlaer:
As you requested, I have made a list of books from the chest of tomes discovered by Daeruth -- may she emerge from her icy curse! -- under Thorin's Halls that have absolutely nothing to do with Dwarrow-gems. Some of them are about gems, but written in a didactic mode by our own hir Silwë. But none of what we have read cover to cover so far has anything to do with the topics you are searching for. We have, of course, more tomes yet to go.
Not at all relevant:
