I would never, love! It’s not dumb at all!
So the traditional royal family order – the one worn by Camilla, Sophie, Diana – is made of ivory. William is an outspoken and active opponent of the illegal ivory trade, and has spent much of his royal life promoting conservation and combatting poachers, the illegal trade, that sort of thing. It was a theory that Catherine hadn’t yet gotten the order from HM because it’s made of ivory, and that would have been a slap in the face to William. Kate’s order is made of glass, which means HM consciously made a few decisions – first, to grant her granddaughter in law this very big honor, and second, to do it in a way that honors her grandson and eventual heir’s wishes. It’s a huge success for William and Catherine. Convincing HM to change anything isn’t easy, but at least one of them convinced HM to do this. It’s a really, really big deal.
