I would like to ask a question about some jewellery worn by the Duchess of Gloucester. We know that her Bandeau Tiara can be worn with either diamonds or emerald and that she also has a set of ruby clup brooches. What I am wondering is, is it possible that all three are the same clip brooches with different centres. I think that the ruby is a bit stouter than the emerald and diamond but I wondered what you thought.
