Just wanted to say, that both of the jewelry gives me Crowley vibes.
The necklace in the right is Crowley before his fall. Red is because of his hair and those stars reminds me of his fascination of space. He was exited talking about them with Aziraphale and also the main color in this scene was red (as I remember).
The bracelet on the left is after his fall. It's black and has angel wings. It could be his wings and the little angel would be a reminder of who he was before he became a demon or maybe it is his angelic husband.
wait... so s1 says angels don't dance, except for aziraphale, who learned the gavotte in the late 1880s
but then we learn in s2 that aziraphale did at least one other dance earlier !
so what i'm wondering is,, how did it even start? like did aziraphale go "gosh I'm really sorry fr 🥺😬 allow me to prove it with this incredibly human ritual no angel has ever tried before"? or did crowley go "oh, how to make me feel better you ask? do a little dance go on 😈🐍🥰"?
anyway the point is crowley canonically got to see aziraphale dance for that very first time !
1650: the first time an angel ever danced, and it was to apologize for some silly dumbfuckery so his demon spouse would drop the pout & join him for lunch
i personally love aziraphale in the background during the scene where crowley is trying to fool shax and the other demons because he has no idea what crowley is talking about but he is standing behind him like "yep my clever and pretty husband knows what he is doing so i'll just roll with it"
