A long time ago, we discussed the little 'pin', Queen Alexandra seems to wear at the base of her fringe tiara. While searching for serpent jewellery for another threat, I 'stumbled' over these two pictures of Queen Alexandra. For me it seems like HM wore the little bracelet attached to the base of the fringe tiara. So no pin, but a bracelet.
If this is already known, my apologies for repeating .
