I don't know who told you that there is such a thing as a Weaver's Torque, but no such thing exists in the game (yet; crafting torques for all the crafts that didn't get one years ago are being added soon based on some upcoming patch info that Matsui posted)
Every FoV/GoV zone has one particular "unique" item that can drop from its boxes, and for Ru'Avitau it happens to be the Terminus Earring. You might have been looking for the torque in the nearby zone of Ve'Lugannon Palace, but that one is the Alchemist's Torque, not for CC.
