Alright, that's what I thought. I saw the price in the sticky saying a perfect req9 one is worth up to 100k, and it figures that I'm unlucky enough to find an armor 15 one, but I wanted to make sure that it's worthless before I salvage it or whatever.
Diamonds have been salvaged from these before so my advice is to add a highly salvageable inscription (assuming it is from nf) then gogogo expert salvage gl.
