Used Dragon Age Inquisition
A number of the things into the valuables category are used for looking into your enemies; these could be converted into the dining table next to Minaeve - a pursuit in Haven should arrive early to share with you about that.
An identical table will undoubtedly be within the tower in Skyhold following the Inquisition moves indeed there.
A number of the things in this group are also utilized for requisitions. Since you'll find nothing to indicate which valuables are or aren't used in all of them, plus the location requisitions seem to be repeatable infinitely (it just picks another arbitrary one from the listing for the location each and every time), it's most likely not all that safe to offer any valuables, if you don't will get a listing of all of the requisitions. That said, considering that the location requisitions only actually provide Power, you could simply disregard them, and only hoard valuables if they're found in a differnt one.
Oh, and of course, there's also the ability to mark products in other groups as valuables, therefore essentially any item are when you look at the valuables group. This is apparently meant in an effort to mark things for later on sale, by hitting market All from the valuables category as soon as you arrive at a shop. This works alright, offered you submit research first, but only when you never value the requisition things being lost.
