Isn't there historically a triple "ring" around the Tiara? Or could this be the new, updated one for the new style and contemporary times for the Vatican. It could be poised as that. So many long to see the Holy Father use it once in a while. Perhaps in a new ceremonial, some way, just to see that lens of continuity at work, so that it does not appear abandoned forever. It has been too long and it is still the symbol of the Pope.
