Was Cobb wearing a ring during the ending?

Excuse me, but I couldn't help but notice something in the ending of the film. Could you clarify for me, was Cobb indeed wearing a ring during that pivotal moment? It seemed to me that the ring could hold some significance, perhaps a subtle nod to his marital status or a deeper metaphor within the narrative. I'd appreciate your thoughts on this detail, as it's been lingering in my mind since I watched the film.
