What are the rules on who's invited or who's going to the coronation? Is it only peers and peeresses (suo jure and wives of peers)? Will it include sons and daughters of peers, and widowed ones (the dowagers)? Are divorced wives of peers who did not remarry be allowed? How about those from non-reigning nobility and royal houses?
Is it just me or could there be another Snowdon tiara waiting to be worn and the coronation? I have this feeling that had the 1st Earl of Snowdon (Tony Armstrong-Jones) be still alive, he wouldn't allow that his own family would not have a tiara of their own. It's possible he left designs of possible coronation tiaras that David would ask to create. Given they're a family of artists. Their heraldry symbol is the stag (Tony and David's signet rings have the stag design). Hypothetical thinking...the Snowdon Stag Tiara?
I'd love to see Serena to attend the coronation even if she won't be seated with David. She might sit with her stepmother, Anita, the Countess of Harrington, and father The Earl of Harrington, and/or with her stepmother-in-law, Lucy, the Dowager Countess of Snowdon.
What could Lady Margarita wear? Seems that Serena is not into jewelry despite her highly aristocratic background, and David could have sold everything hmmm. What if Margarita herself designs her jewels since she's dabbling into making jewelries (as per her Instagram portfolio).
