While I'm not going to say that it is not, my best guess based on the circumstances is No, not likely made of metal in the terms that I think you are suggesting.
Recap. YES: - Item - Worn - Visible NO: - Chest Slot - Plate type [but this might be misleading] - Tradeskills involved - Not within 450-490nm wavelength of visibly reflected light [Blue] - Looted from NPC - Obtained from a loot chest - Shield - Likely made of Metal - Dragons harmed in creation of the item
Symmetrical: Something that is symmetrical has corresponding similar parts: in other words, one side is the same as the other. If you can draw a line down the center of something and get two similar halves, it’s symmetrical.
When part of a pair the item would have symmetry, but I believe that would be true of any two of the same item? The item, singular, is not symmetrical. Sorry, I think I overthought that one. You could not fold a single one of this item and have resulting sides mirror each other exactly. So, going with No.
