clearest image of ring i have found so far.
appears he wears it on both hands, but is ALWAYS wearing it, in comparison to his wedding ring.
He wears this ring in place of his wedding ring at times on his left hand, doesn’t wear wedding ring. He wears it on his right hand, when he does wear his wedding ring.
Whatever it is, he values it more than his marriage ring.
