Missing a Orphea's Empyrean Piece

Currently I am sitting at 9/10 Orphea’s Empyrean pieces for my second week of doing hard raids at 1370 to get my last piece of gear gold. Is there anyway to provide me with one piece or even reset one of my weekly dungeons I am willing to do it again. Just don’t want to be stuck below 1385 because I cant upgrade my gear.
