Witches’ Tiaras/Crowns

So basically there’re some witches have tiaras/crowns when they’re in full power, Wanda, Billy and Rio got theirs, we see Agatha‘s mother’s when see tries to kill Agatha. So I was wondering, what would Agatha‘s tiara/crow look like, knowing it would be purple.

and also with curiosity, what would yours be like?
mine would a simple silver braided wire hope with blue gem in the middle
